National Center 2. Operationally, the timing for prognostication is typically at least 5 days after ROSC for patients treated with TTM (which is about 72 hours after normothermia) and should be conducted under conditions that minimize the confounding effects of sedating medications. The majority of recommendations are based on Level C evidence, including those based on limited data (123 recommendations) and expert opinion (31 recommendations). Open-chest CPR can be useful if cardiac arrest develops during surgery when the chest or abdomen is already open, or in the early postoperative period after cardiothoracic surgery. experience, training, tools, and skills of the provider when choosing an approach to airway management. In comparison, surveillance and prevention are critical aspects of IHCA. 2. Benefits of this method are a standard and reproducible assessment. Twelve observational studies evaluated NSE collected within 72 hours after arrest. Although case reports describe good outcomes after the use of ECMO6 and IV lipid emulsion therapy710 for severe sodium channel blocker cardiotoxicity, no controlled human studies could be found, and limited animal data do not support lipid emulsion efficacy.11, No human controlled studies were found evaluating treatment of cardiac arrest due to TCA toxicity, although 1 study demonstrated termination of amitriptyline-induced VT in dogs.12, This topic last received formal evidence review in 2010.25. Outcomes from IHCA are overall superior to those from OHCA,5 likely because of reduced delays in initiation of effective resuscitation. Other pseudoelectrical therapies, such as cough CPR, fist or percussion pacing, and precordial thump have all been described as temporizing measures in select patients who are either periarrest or in the initial seconds of witnessed cardiac arrest (before losing consciousness in the case of cough CPR) when definitive therapy is not readily available. An approach using lower tidal volumes, lower respiratory rate, and increased expiratory time may minimize the risk of auto-PEEP and barotrauma. After return of spontaneous breathing, patients should be observed in a healthcare setting until the risk of recurrent opioid toxicity is low and the patients level of consciousness and vital signs have normalized. Torsades de pointes is a form of polymorphic VT that is associated with a prolonged heart ratecorrected QT interval when the rhythm is normal and VT is not present. There is no conclusive evidence of superiority of one biphasic shock waveform over another for defibrillation. It is preferable to avoid hypotension by maintaining a systolic blood pressure of at least 90 mm Hg and a mean arterial pressure of at least 65 mm Hg in the postresuscitation period. In February 2003, President Bush issued . The Level of Evidence (LOE) is based on the quality, quantity, relevance, and consistency of the available evidence. Enters information concerning calls for technical support and security related patrol activity into a Computer Aided Dispatch (CAD) system to be forwarded to the appropriate police dispatch station for assignment. The nurse assesses a responsive adult and determines she is choking. In postcardiac surgery patients who are refractory to standard resuscitation procedures, mechanical circulatory support may be effective in improving outcome. Administration of IV amiodarone, procainamide, or sotalol may be considered for the treatment of wide-complex tachycardia. Normal brain has a GWR of approximately 1.3, and this number decreases with edema. More research in this area is clearly needed. If so, what dose and schedule should be used? There are some physiological basis and preclinical data for hyperoxemia leading to increased inflammation and exacerbating brain injury in postarrest patients. The location of the emergency (e.g. Survivorship plans that address treatment, surveillance, and rehabilitation need to be provided at hospital discharge to optimize transitions of care to the outpatient setting. Urgent support of airway, breathing, and circulation is essential in suspected anaphylactic reactions. Which intervention should the nurse implement? 1. The pharmacokinetic properties, acute effects, and clinical efficacy of emergency drugs have primarily been described when given intravenously. needed to be able to compare prognostic values across studies. Recommendation 1 is supported by the 2019 focused update on ACLS guidelines.3 Recommendation 2 last received formal evidence review in 2015.4 Recommendation 3 is supported by the 2020 CoSTR for ALS.11, These recommendations are supported by the 2015 Guidelines Update24 and a 2020 evidence update.11. Neglect the mass and friction of all pulleys and determine the acceleration of each cylinder and the tensions T1T_1T1 and T2T_2T2 in the two cables. a. This topic last received formal evidence review in 2010.22. You and your colleagues are performing CPR on a 6-year-old child. You have assessed your patient and recognized that they are in cardiac arrest. How does this affect compressions and ventilations? The paucity of information on the efficacy of IO drug administration during CPR was acknowledged in 2010, but since then the IO route has grown in popularity. Cyanide reversibly binds to the ferric ion cytochrome oxidase in the mitochondria and stops cellular respiration and adenosine triphosphate production. This topic last received formal evidence review in 2010.10, Local anesthetic overdose (also known as local anesthetic systemic toxicity, or LAST) is a life-threatening emergency that can present with neurotoxicity or fulminant cardiovascular collapse.1,2 The most commonly reported agents associated with LAST are bupivacaine, lidocaine, and ropivacaine.2, By definition, LAST is a special circumstance in which alternative approaches should be considered in addition to standard BLS and ALS. 2. Survival and recovery from adult cardiac arrest depend on a complex system working together to secure the best outcome for the victim. Response. Protocols for management of OHCA in pregnancy should be developed to facilitate timely transport to a center with capacity to immediately perform perimortem cesarean delivery while providing ongoing resuscitation. Individual test modalities may be obtained earlier and the results integrated into the multimodality assessment synthesized at least 72 hours after normothermia. Maintaining the arterial partial pressure of carbon dioxide (Paco2) within a normal physiological range (generally 3545 mm Hg) may be reasonable in patients who remain comatose after ROSC. Although cardiac arrest due to carbon monoxide poisoning is almost always fatal, studies about neurological sequelae from less-severe carbon monoxide poisoning may be relevant. arrest with shockable rhythm? The opioid epidemic has resulted in an increase in opioid-associated out-of-hospital cardiac arrest, with the mainstay of care remaining the activation of the emergency response systems and performance of high-quality CPR. Sparse data have been published addressing this question. Neurologic prognostication incorporates multiple diagnostic tests which are synthesized into a comprehensive multimodal assessment at least 72 hours after return to normothermia and with sedation and analgesia limited as possible. A 2020 ILCOR systematic review. We recommend structured assessment for anxiety, depression, posttraumatic stress, and fatigue for cardiac arrest survivors and their caregivers. A number of case reports have shown good outcomes in patients who received double sequential defibrillation. Check for no breathing or only gasping; if none, begin CPR with compressions. There are a number of case reports and case series that examined the use of fist pacing during asystolic or life-threatening bradycardic events. 1. 2. Part 2: Evidence Evaluation and Guidelines Development, Part 3: Adult Basic and Advanced Life Support, Part 4: Pediatric Basic and Advanced Life Support, Part 9: COVID-19 Interim Guidance for Healthcare Providers, Part 10: COVID-19 Interim Guidance for EMS, 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Cocaine toxicity can cause adverse effects on the cardiovascular system, including dysrhythmia, hypertension, tachycardia and coronary artery vasospasm, and cardiac conduction delays. 3-3 Hurricane Season Preparation Annually, at the beginning of hurricane season (June 1), the H-EOT, the Office of Licensing , R-EOT, and Early high-quality CPR You are providing care for Mrs. Bove, who has an endotracheal tube in place. As with all AHA guidelines, each 2020 recommendation is assigned a Class of Recommendation (COR) based on the strength and consistency of the evidence, alternative treatment options, and the impact on patients and society (Table 1(link opens in new window)). Because of potential interference with maternal resuscitation, fetal monitoring should not be undertaken during cardiac arrest in pregnancy. Typical Rapid Response System Calling Criteria. 1. Similar challenges were faced in the 2020 Guidelines process, where a number of critical knowledge gaps were identified in adult cardiac arrest management. She is 28 weeks pregnant and her fundus is above the umbilicus. Intracardiac drug administration was discouraged in the 2000 AHA Guidelines for CPR and Emergency Cardiovascular Care given its highly specialized skill set, potential morbidity, and other available options for access.1,2 Endotracheal drug administration results in low blood concentrations and unpredictable pharmacological effect and has also largely fallen into disuse given other access options. Thus, the ultimate decision of the use, type, and timing of an advanced airway will require consideration of a host of patient and provider characteristics that are not easily defined in a global recommendation. 2. The most common cause of ventilation difficulty is an improperly opened airway. A 2020 ILCOR systematic review found that most studies did not find a significant association between real-time feedback and improved patient outcomes. You and your co-worker Jake are operating a BVM during multiple-provider CPR for an adult. Artifact-filtering and other innovative techniques to disclose the underlying rhythm beneath ongoing CPR can surmount these challenges and minimize interruptions in chest compressions while offering a diagnostic advantage to better direct therapies. Time to drug in IHCA is generally much shorter, and the effect of epinephrine on outcomes in the IHCA population may therefore be different. Does avoidance of hyperoxia in the postarrest period lead to improved outcomes? Several RCTs have compared a titrated approach to oxygen administration with an approach of administering 100% oxygen in the first 1 to 2 hours after ROSC. We recommend targeted temperature management for pregnant women who remain comatose after resuscitation from cardiac arrest. It is reasonable to place defibrillation paddles or pads on the exposed chest in an anterolateral or anteroposterior position, and to use a paddle or pad electrode diameter more than 8 cm in adults. Carbon monoxide poisoning reduces the ability of hemoglobin to deliver oxygen and also causes direct cellular damage to the brain and myocardium, leading to death or long-term risk of neurological and myocardial injury. Rescuers should avoid excessive ventilation (too many breaths or too large a volume) during CPR. It is reasonable to immediately resume chest compressions after shock delivery for adults in cardiac arrest in any setting. Few patients who develop cardiac arrest from carbon monoxide poisoning survive to hospital discharge, regardless of the treatment administered after ROSC, though rare good outcomes have been described. Once reliable measurement of peripheral blood oxygen saturation is available, avoiding hyperoxemia by titrating the fraction of inspired oxygen to target an oxygen saturation of 92% to 98% may be reasonable in patients who remain comatose after ROSC. Are NSE and S100B helpful when checked later than 72 h after ROSC? 3. Coronary artery disease (CAD) is prevalent in the setting of cardiac arrest.14 Patients with cardiac arrest due to shockable rhythms have demonstrated particularly high rates of severe CAD: up to 96% of patients with STEMI on their postresuscitation ECG,2,5 up to 42% for patients without ST-segment elevation,2,57 and 85% of refractory out-of-hospital VF/VT arrest patients have severe CAD.8 The role of CAD in cardiac arrest with nonshockable rhythms is unknown. The 2015 American College of Cardiology, AHA, and Heart Rhythm Society Guidelines evaluated and recommended adenosine as a first-line treatment for regular SVT because of its effectiveness, extremely short half-life, and favorable side-effect profile. 1. CT indicates computed tomography; ROSC, return of spontaneous circulation; and STEMI, ST-segment elevation myocardial infarction. In addition, it may be helpful for providers to master an advanced airway strategy as well as a second (backup) strategy for use if they are unable to establish the first-choice airway adjunct.

For adults in cardiac arrest receiving ventilation, tidal volumes of approximately 500 to 600 mL, or enough to produce visible chest rise, are reasonable. Studies confirm the importance of real-time disaster monitoring systems, emergency response systems, and information systems these days to mitigate devastating impacts on human life, economy, and . External chest compressions should be performed if emergency resternotomy is not immediately available. Its use as a neuroprognostic tool is promising, but the literature is limited by several factors: lack of standardized terminology and definitions, relatively small sample sizes, single center study design, lack of blinding, subjectivity in the interpretation, and lack of accounting for effects of medications. In adult victims of cardiac arrest, it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min. Chest compressions are the most critical component of CPR, and a chest compressiononly approach is appropriate if lay rescuers are untrained or unwilling to provide respirations. In addition, status myoclonus may have an EEG correlate that is not clearly ictal but may have prognostic meaning, and additional research is needed to delineate these patterns. If you turn off Call with Hold and Release or Call with 5 Button Presses, you can still use the Emergency SOS slider to make a call. reliably checking a pulse, is initiation of CPR beneficial? For patients with severe hypothermia (less than 30C [86F]) with a perfusing rhythm, core rewarming is often used. The system operates 24-hours a day, 7-days a week and includes, but is not limited to, after hours on call staff, telephone and in person screening, outreach, and networking with hospital emergency rooms and police. While amiodarone is typically considered a rhythm-control agent, it can effectively reduce ventricular rate with potential use in patients with congestive heart failure where -adrenergic blockers may not be tolerated and nondihydropyridine calcium channel antagonists are contraindicated. 4. The controlled administration of IV potassium for ventricular arrhythmias due to severe hypokalemia may be useful, but case reports have generally included infusion of potassium and not bolus dosing. Data on the relative benefit of continuous versus intermittent EEG are limited. The suggestion to administer epinephrine was strengthened to a recommendation based on a systematic review and meta-analysis. In addition to standard ACLS, several therapies have long been recommended to treat life-threatening hyperkalemia. Answers Emergency 911 and non-emergency telephone calls for police, security, and technical support events and services. For patients known or suspected to be in cardiac arrest, in the absence of a proven benefit from the use of naloxone, standard resuscitative measures should take priority over naloxone administration, with a focus on high-quality CPR (compressions plus ventilation). Does the treatment of nonconvulsive seizures, common in postarrest patients, improve patient Vagal maneuvers are recommended for acute treatment in patients with SVT at a regular rate. 4. The BLS care of adolescents follows adult guidelines. It can be beneficial for rescuers to avoid leaning on the chest between compressions to allow complete chest wall recoil for adults in cardiac arrest. We recommend that the findings of a best motor response in the upper extremities being either absent or extensor movements not be used alone for predicting a poor neurological outcome in patients who remain comatose after cardiac arrest. This is a rare opportunity to gain experience working at one of the most sophisticated Security Alarm monitoring and security command centers in North America and be part of a high-performing team . 1. In accordance with the BSEE Safety and Environment Management System II, an Emergency Action Plan (EAP) should be in place. For each recommendation, the writing group discussed and approved specific recommendation wording and the COR and LOE assignments. General Preparedness and Response 2. 4. Active compression-decompression CPR might be considered for use when providers are adequately trained and monitored. When performed with other prognostic tests, it may be reasonable to consider persistent status epilepticus 72 h or more after cardiac arrest to support the prognosis of poor neurological outcome. How is a child defined in terms of CPR/AED care? Should severely hypothermic patients in VF who fail an initial defibrillation attempt receive additional Many of the tests considered are subject to error because of the effects of medications, organ dysfunction, and temperature. The prompt initiation of CPR is perhaps the most important intervention to improve survival and neurological outcomes. During manual CPR, rescuers should perform chest compressions to a depth of at least 2 inches, or 5 cm, for an average adult while avoiding excessive chest compression depths (greater than 2.4 inches, or 6 cm). Determining the utility of such physiological monitoring or diagnostic procedures is important. In addition, deterioration of fetal status may be an early warning sign of maternal decompensation. 1. Many of these techniques and devices require specialized equipment and training. Tap Emergency SOS. 1. Recommendations for the treatment of cardiac arrest due to hyperkalemia, including the use of calcium and sodium bicarbonate, are presented in Electrolyte Abnormalities. These recommendations are supported by the 2019 focused update on ACLS guidelines.1. These include mechanical CPR, impedance threshold devices (ITD), active compression-decompression (ACD) CPR, and interposed abdominal compression CPR. receiving CPR with ventilation? How does integrated team performance, as opposed to performance on individual resuscitation skills, 3. shock or electric instability improve outcomes? Epinephrine is the cornerstone of treatment for anaphylaxis.35, This topic last received formal evidence review in 2010.14. 1. In situations such as nonsurvivable maternal trauma or prolonged pulselessness, in which maternal resuscitative efforts are considered futile, there is no reason to delay performing perimortem cesarean delivery in appropriate patients. A wide-complex tachycardia can be regular or irregularly irregular and have uniform (monomorphic) or differing (polymorphic) QRS complexes from beat to beat. If no emergency medical services (EMS) or other trained personnel is on the scene, activate the 911 emergency system immediately. Recommendations for management of torsades de pointes are also presented in Torsades de Pointes. These effects can also precipitate acute coronary syndrome and stroke. Initial management should focus on support of the patients airway and breathing. 3. When performed with other prognostic tests, it may be reasonable to consider extensive areas of restricted diffusion on brain MRI at 2 to 7 days after cardiac arrest to support the prognosis of poor neurological outcome in patients who remain comatose. One study of patients with laryngectomies showed that a pediatric face mask created a better peristomal seal than a standard ventilation mask. Once an emergency occurs, the ERT leader should take charge of managing the emergency itself, and the leader of the CMT should begin coordinating . When the QRS complex of a VT is of uniform morphology, electric cardioversion with the shock synchronized to the QRS minimizes the risk of provoking VF by a mistimed shock during the vulnerable period of the cardiac cycle (T wave). referral to rehabilitation services or patient outcomes? Since this topic was last updated in detail in 2015, at least 2 randomized trials have been completed on the effect of steroids on shock and other outcomes after ROSC, only 1 of which has been published to date. When appropriate, flow diagrams or additional tables are included. Although there is no evidence examining the effectiveness of their use during cardiac arrest, oropharyngeal and nasopharyngeal airways can be used to maintain a patent airway and facilitate appropriate ventilation by preventing the tongue from occluding the airway. Three studies evaluated quantitative pupillary light reflex. 1. In patients with persistent hemodynamically unstable bradycardia refractory to medical therapy, temporary transvenous pacing is reasonable to increase heart rate and improve symptoms. This recommendation is based on the fact that nonconvulsive seizures are common in postarrest patients and that the presence of seizures may be important prognostically, although whether treatment of nonconvulsive seizures affects outcome in this setting remains uncertain. Acknowledging these data, the use of mechanical CPR devices by trained personnel may be beneficial in settings where reliable, high-quality manual compressions are not possible or may cause risk to personnel (ie, limited personnel, moving ambulance, angiography suite, prolonged resuscitation, or with concerns for infectious disease exposure). 1. If the patient presents with SVT, the primary goal of treatment is to quickly identify and treat patients who are hemodynamically unstable (ischemic chest pain, altered mental status, shock, hypotension, acute heart failure) or symptomatic due to the arrhythmia. 3. affect resuscitation outcomes? Simultaneous compressions and ventilation should be avoided,2 but delivery of chest compressions without pausing for ventilation seems a reasonable option.3 The use of SGAs adds to this complexity because efficiency of ventilation during cardiac arrest may be worse than when using an endotracheal tube, though this has not been borne out in recently published RCTs.4,5, This topic last received formal evidence review in 2010.15, These recommendations are supported by the 2017 focused update on adult BLS and CPR quality guidelines.20. Agonal breathing is described by lay rescuers with a variety of terms including, Protracted delays in CPR can occur when checking for a pulse at the outset of resuscitation efforts as well as between successive cycles of CPR. 5. Nonvasopressor medications during cardiac arrest. Twelve studies examined the use of naloxone in respiratory arrest, of which 5 compared intramuscular, intravenous, and/or intranasal routes of naloxone administration (2 RCT. When switching roles, you should minimize interruptions in chest compressions to less than how many seconds? A recent meta-analysis of 13 RCTs (990 evaluable patients) found that adverse events and serious adverse events were more common in patients who were randomized to receive flumazenil than placebo (number needed to harm: 5.5 for all adverse events and 50 for serious adverse events). 2, and 3. Either bag-mask ventilation or an advanced airway strategy may be considered during CPR for adult cardiac arrest in any setting depending on the situation and skill set of the provider. If an advanced airway is used, a supraglottic airway can be used for adults with OHCA in settings with low tracheal intubation success rates or minimal training opportunities for endotracheal tube placement. Recent evidence, however, suggests that the risk of major bleeding is not significantly higher in cardiac arrest patients receiving thrombolysis. Biphasic and monophasic shock waveforms are likely equivalent in their clinical outcome efficacy. Phone or ask someone to phone 9-1-1 (the phone or caller with the phone remains at the victim's side, with the phone on speaker mode). For severe symptomatic bradycardia causing shock, if no IV or IO access is available, immediate transcutaneous pacing while access is being pursued may be undertaken. The use of an airway adjunct (eg, oropharyngeal and/or nasopharyngeal airway) may be reasonable in unconscious (unresponsive) patients with no cough or gag reflex to facilitate delivery of ventilation with a bag-mask device. These topics were identified as not only areas where no information was identified but also where the results of ongoing research could impact the recommendation directly. We do not recommend routine use of magnesium for the treatment of polymorphic VT with a normal QT interval. CPR is the single-most important intervention for a patient in cardiac arrest, and chest compressions should be provided promptly. Which statement about bag-valve-mask (BVM) resuscitators is true? 1. The precordial thump may be considered at the onset of a rescuer-witnessed, monitored, unstable ventricular tachyarrhythmia when a defibrillator is not immediately ready for use and is performed without delaying CPR or shock delivery. 4. Each recommendation was developed and formally approved by the writing group. To assure successful maternal resuscitation, all potential stakeholders need to be engaged in the planning and training for cardiac arrest in pregnancy, including the possible need for PMCD. However, there are several case reports of good maternal and fetal outcome with the use of TTM after cardiac arrest. 2. These recommendations are supported by the 2015 ACC/AHA/HRS Guideline for the Management of Adult Patients With SVT: A Report of the American College of Cardiology/AHA Task Force on Clinical Practice Guidelines and the Heart Rhythm Society.6, These recommendations are supported by the 2015 American College of Cardiology, AHA, and Heart Rhythm Society Guidelines for the Management of Adult Patients With SVT.6. However, electric cardioversion may not be effective for automatic tachycardias (such as ectopic atrial tachycardias), entails risks associated with sedation, and does not prevent recurrences of the wide-complex tachycardia. How does this affect compressions and ventilations? A more detailed approach to rhythm management is found elsewhere.13, This topic last received formal evidence review in 2010.17, Polymorphic VT refers to a wide-complex tachycardia of ventricular origin with differing configurations of the QRS complex from beat to beat.
