Shout for nearby help. Early activation of the emergency response system is critical for patients with suspected opioid overdose. What is the sixth link in the Adult In-Hospital Cardiac Chain of Survival? 1. Benzodiazepine overdose causes CNS and respiratory depression and, particularly when taken with other sedatives (eg, opioids), can cause respiratory arrest and cardiac arrest. The nurse assesses a responsive adult and determines she is choking. It may be reasonable to use audiovisual feedback devices during CPR for real-time optimization of CPR performance. Pharmacological treatment of cardiac arrest is typically deployed when CPR with or without attempted defibrillation fails to achieve ROSC. There are no randomized trials of the use of TTM in pregnancy. Electrolyte abnormalities may cause or contribute to cardiac arrest, hinder resuscitative efforts, and affect hemodynamic recovery after cardiac arrest. Patients who respond to naloxone administration may develop recurrent CNS and/or respiratory depression. IV diltiazem or verapamil can be effective for acute treatment in patients with hemodynamically stable SVT at a regular rate. In cases of prehospital maternal arrest, rapid transport directly to a facility capable of PMCD and neonatal resuscitation, with early activation of the receiving facilitys adult resuscitation, obstetric, and neonatal resuscitation teams, provides the best chance for a successful outcome. ECPR may be considered for select cardiac arrest patients for whom the suspected cause of the cardiac arrest is potentially reversible during a limited period of mechanical cardiorespiratory support. 3. When bradycardia is refractory to medical management and results in severe symptoms, the reasonable next step is placement of a temporary pacing catheter for transvenous pacing. Hyperkalemia is commonly caused by renal failure and can precipitate cardiac arrhythmias and cardiac arrest. 1. There are no studies comparing different strategies of opening the airway in cardiac arrest patients. Early high-quality CPR You are providing high-quality CPR on a 6-year-old patient who weighs 44 pounds. Does epinephrine, when administered early after cardiac arrest, improve survival with favorable Because chest compression fraction of at least 60% is associated with better resuscitation outcomes, compression pauses for ventilation should be as short as possible. Typical Rapid Response System Calling Criteria. Its effects are mediated by a different mechanism and are longer lasting than adenosine. Most opioid-associated deaths also involve the coingestion of multiple drugs or medical and mental health comorbidities.47. It may be reasonable to perform defibrillation attempts according to the standard BLS algorithm concurrent with rewarming strategies. Which is the most effective CPR technique to perform until help arrives? Evidence for the effectiveness of -adrenergic blockers in terminating SVT is limited. One important consideration is the selection of patients for ECPR and further research is needed to define patients who would most benefit from the intervention. More uniform definitions for status epilepticus, malignant EEG patterns, and other EEG patterns are In a trial that compared esmolol with diltiazem, diltiazem was more effective in terminating SVT. It is reasonable that TTM be maintained for at least 24 h after achieving target temperature. These recommendations are supported by the 2020 CoSTR for ALS.11, Recommendation 1 last received formal evidence review in 2010 and is supported by the Guidelines for the Use of an Insulin Infusion for the Management of Hyperglycemia in Critically Ill Patients from the Society for Critical Care Medicine.49 Recommendation 2 is supported by the 2020 CoSTR for ALS.11 Recommendations 3 and 4 last received formal evidence review in 2015.24. Community reintegration and return to work or other activities may be slow and depend on social support and relationships. Antidigoxin Fab antibodies should be administered to patients with severe cardiac glycoside toxicity. The presence of undifferentiated myoclonic movements after cardiac arrest should not be used to support a poor neurological prognosis. What is a reason you would choose to perform chest thrusts instead of abdominal thrusts for an adult or child with an obstructed airway? Adenosine should not be administered for hemodynamically unstable, irregularly irregular, or polymorphic wide-complex tachycardias. 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). You are preparing to deliver ventilations to an adult patient experiencing respiratory arrest. If increased auto-PEEP or sudden decrease in blood pressure is noted in asthmatics receiving assisted ventilation in a periarrest state, a brief disconnection from the bag mask or ventilator with compression of the chest wall to relieve air-trapping can be effective. Are you performing all of the required ITM on your Emergency Power Supply System? For example, patients with severe hypoxia and impending respiratory failure may suddenly develop a profound bradycardia that leads to cardiac arrest if not addressed immediately. You do not see signs of life-threatening bleeding. How is a child defined in terms of CPR/AED care? Rescuers should provide CPR, including rescue breathing, as soon as an unresponsive submersion victim is removed from the water. You recognize that a task has been overlooked. 5. The healthcare provider should minimize the time taken to check for a pulse (no more than 10 s) during a rhythm check, and if the rescuer does not definitely feel a pulse, chest compressions should be resumed. The topic of neuroprotective agents was last reviewed in detail in 2010. 4. Alternatives to IV access for acute drug administration include IO, central venous, intracardiac, and endotracheal routes. Does targeted temperature management, compared to strict normothermia, improve outcomes? As more and more centers and EMS systems are using feedback devices and collecting data on CPR measures such as compression depth and chest compression fraction, these data will enable ongoing updates to these recommendations. In the PRIMED study (n=8178), the use of the ITD (compared with a sham device) did not significantly improve survival to hospital discharge or survival with good neurological function in patients with OHCA. 3. How is a child defined in terms of CPR/AED care? Compression rate and compression depth, for example, have both been associated with better outcomes, yet these variables have been found to be inversely correlated with each other so that improving one may worsen the other.13 CPR quality interventions are often applied in bundles, making the benefit of any one specific measure difficult to ascertain. In an emergency, the individual can press a call button to signal for help. Immediate defibrillation is reasonable for provider-witnessed or monitored VF/pVT of short duration when a defibrillator is already applied or immediately available. 3. A lone healthcare provider should commence with chest compressions rather than with ventilation. carotid or femoral artery you are alone performing high-quality CPR when a second provider arrives to take over compressions. If an arterial line is in place, an abrupt increase in diastolic pressure or the presence of an arterial waveform during a rhythm check showing an organized rhythm may indicate ROSC. If a regular wide-complex tachycardia is suspected to be paroxysmal SVT, vagal maneuvers can be considered before initiating pharmacological therapies (see Regular Narrow-Complex Tachycardia). A comprehensive, structured, multidisciplinary system of care should be implemented in a consistent manner for the treatment of postcardiac arrest patients. However, biphasic waveform defibrillators (which deliver pulses of opposite polarity) expose patients to a much lower peak electric current with equivalent or greater efficacy for terminating atrial. 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. VF is the presenting rhythm in 25% to 50% of cases of cardiac arrest after cardiac surgery. Accurate neurological prognostication is important to avoid inappropriate withdrawal of life-sustaining treatment in patients who may otherwise achieve meaningful neurological recovery and also to avoid ineffective treatment when poor outcome is inevitable (Figure 10).3. A. Identifying and treating early clinical deterioration B. 3. Opioid overdoses deteriorate to cardiopulmonary arrest because of loss of airway patency and lack of breathing; therefore, addressing the airway and ventilation in a periarrest patient is of the highest priority. 1. Data on the relative benefit of continuous versus intermittent EEG are limited. These recommendations are supported by the 2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation: A Report of the American College of Cardiology/AHA Task Force on Practice Guidelines and the Heart Rhythm Society18 as well as the focused update of those guidelines published in 2019.2, These recommendations are supported by 2014 AHA, American College of Cardiology, and Heart Rhythm Society Guideline for the Management of Patients With Atrial Fibrillation18 as well as the focused update of those guidelines published in 2019.2. 1. 3. Effective ventilation of the patient with a tracheal stoma may require ventilation through the stoma, either by using mouth-to-stoma rescue breaths or by use of a bag-mask technique that creates a tight seal over the stoma with a round, pediatric face mask. 2. Whether resumption of CPR immediately after shock might reinduce VF/VT is controversial.52-54 This potential concern has not been borne out by any evidence of worsened survival from such a strategy. Two small studies have demonstrated improved hemodynamic effects of open-chest CPR when compared with external chest compressions in cardiac surgery patients. What is the optimal duration for targeted temperature management before rewarming? Limited animal data and rare case reports suggest possible utility of calcium to improve heart rate and hypotension in -adrenergic blocker toxicity.

Toxicity: carbon monoxide, digoxin, and cyanide. It is reasonable for prehospital ALS providers to use the adult ALS TOR rule to terminate resuscitation efforts in the field for adult victims of OHCA. In patients who remain comatose after cardiac arrest, we recommend that neuroprognostication be delayed until adequate time has passed to ensure avoidance of confounding by medication effect or a transiently poor examination in the early postinjury period. This cause of death is especially prominent in those with OHCA but is also frequent after IHCA.1,2 Thus, much of postarrest care focuses on mitigating injury to the brain. Answer: Perform cardiopulmonary resuscitation Explanation: According to the Adult In-Hospital Cardiac Chain of Survival after immediately starting the emergency response system, you should immediately start a cardiopulmonary resuscitation with an emphasis on chest compressions. The response phase is a reaction to the occurrence of a catastrophic disaster or emergency. ECPR refers to the initiation of cardiopulmonary bypass during the resuscitation of a patient in cardiac arrest. Neuroprognostication that uses multimodal testing is felt to be better at predicting outcomes than is relying on the results of a single test to predict poor prognosis. You are alone caring for a 4-month-old infant who has gone into cardiac arrest. Perimortem cesarean delivery (PMCD) at or greater than 20 weeks uterine size, sometimes referred to as resuscitative hysterotomy, appears to improve outcomes of maternal cardiac arrest when resuscitation does not rapidly result in ROSC (Figure 15).1014 Further, shorter time intervals from arrest to delivery appear to lead to improved maternal and neonatal outcomes.15 However, the clinical decision to perform PMCDand its timing with respect to maternal cardiac arrestis complex because of the variability in level of practitioner and team training, patient factors (eg, etiology of arrest, gestational age), and system resources. ACLS indicates advanced cardiovascular life support; BLS, basic life support; CPR, cardiopulmonary resuscitation; ET, endotracheal; IV, intravenous; and ROSC, 7. 1. shock or electric instability improve outcomes? A 2017 ILCOR systematic review found that a ratio of 30 compressions to 2 breaths was associated with better survival than alternate ratios, a recommendation that was reaffirmed by the AHA in 2018. Emergency/Immediate notification is in response to a significant emergency or dangerous situation involving an immediate threat to the health or safety of students or employees occurring on the campus. Multiple case reports have observed intracranial placement of nasopharyngeal airways in patients with basilar skull fractures. Anterolateral, anteroposterior, anterior-left infrascapular, and anterior-right infrascapular electrode placements are comparably effective for treating supraventricular and ventricular arrhythmias. Performance of high-quality CPR includes adequate compression depth and rate while minimizing pauses in compressions. Status myoclonus is commonly defined as spontaneous or sound-sensitive, repetitive, irregular brief jerks in both face and limb present most of the day within 24 hours after cardiac arrest.8 Status myoclonus differs from myoclonic status epilepticus; myoclonic status epilepticus is defined as status epilepticus with physical manifestation of persistent myoclonic movements and is considered a subtype of status epilepticus for these guidelines. Although the administration of IV magnesium has not been found to be beneficial for VF/VT in the absence of prolonged QT, consideration of its use for cardiac arrest in patients with prolonged QT is advised. An ILCOR systematic review done for 2020 did not specifically address the timing and method of obtaining EEGs in postarrest patients who remain unresponsive. At minimum, one drill per year must be completed for each type of emergency response: evacuation, shelter in place, and hide/run/fight. The electric energy required to successfully cardiovert a patient from atrial fibrillation or atrial flutter to sinus rhythm varies and is generally less in patients with new-onset arrhythmia, thin body habitus, and when biphasic waveform shocks are delivered. A. EEG patterns that were evaluated in the 2020 ILCOR systematic review include unreactive EEG, epileptiform discharges, seizures, status epilepticus, burst suppression, and highly malignant EEG. These deliver different peak currents even at the same programmed energy setting, making comparisons of shock efficacy between devices challenging. After immediately initiating the emergency response system, what is your next action according to the Adult In-Hospital Cardiac Chain of Survival? What is the most efficacious management approach for postarrest cardiogenic shock, including Before embarking on empirical drug therapy, obtaining a 12-lead ECG and/or seeking expert consultation for diagnosis is encouraged, if available. 4. Check for no breathing or only gasping and check pulse (ideally simultaneously). 5. Hemodynamically unstable patients with atrial fibrillation or atrial flutter with rapid ventricular response should receive electric cardioversion. 1. Hemodynamically stable patients can be treated with a rate-control or rhythm-control strategy. The routine use of magnesium for cardiac arrest is not recommended. Which technique should you use to open the patient's airway? 2. The available evidence suggests no appreciable differences in success or major adverse event rates between calcium channel blockers and adenosine.2. 3-3 Hurricane Season Preparation Annually, at the beginning of hurricane season (June 1), the H-EOT, the Office of Licensing , R-EOT, and Follow the telecommunicators instructions. In postcardiac surgery patients with asystole or bradycardic arrest in the ICU with pacing leads in place, pacing can be initiated immediately by trained providers. 1. 2. Can artifact-filtering algorithms for analysis of ECG rhythms during CPR in a real-time clinical setting Toxicity: -adrenergic blockers and calcium Which is the next appropriate action? When 2 or more rescuers are available, it is reasonable to switch chest compressors approximately every 2 min (or after about 5 cycles of compressions and ventilation at a ratio of 30:2) to prevent decreases in the quality of compressions. After immediately initiating the emergency response system, what is your next action according to the in-hospital adult cardiac chain of survival? Two randomized trials from the same center reported improved survival and neurological outcome when steroids were bundled in combination with vasopressin and epinephrine during cardiac arrest and also administered after successful resuscitation from cardiac arrest. One expected challenge faced through this process was the lack of data in many areas of cardiac arrest research. Which statement about bag-valve-mask (BVM) resuscitators is true? The team should provide ventilations at a rate of 1 ventilation every 6 seconds without pausing compressions. A recent consensus statement on this topic has been published by the Society of Thoracic Surgeons.9, This topic last received formal evidence review in 2010.35These recommendations were supplemented by a 2017 review published by the Society of Thoracic Surgeons.9. Some EEG-correlated patterns of status myoclonus may have poor prognosis, but there may also be more benign subtypes of status myoclonus with EEG correlates. You should give 1 ventilation every: After immediately initiating the emergency response system, what is the next link in the Adult In-Hospital Cardiac Chain of Survival? You are providing care for Mrs. Bove, who has an endotracheal tube in place. Uncontrolled tachycardia may impair ventricular filling, cardiac output, and coronary perfusion while increasing myocardial oxygen demand. Survivorship plans that address treatment, surveillance, and rehabilitation need to be provided at hospital discharge to optimize transitions of care to the outpatient setting. 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. 1. 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). 2. Unfortunately, different studies define highly malignant EEG differently or imprecisely, making use of this finding unhelpful.
