Insights

High-quality cardiopulmonary resuscitation (CPR) metrics were similar whether performed at the scene or during transport. These findings indicate that prehospital providers can deliver effective CPR in either location.

Area of Science:

  • Emergency Medicine
  • Cardiovascular Research
  • Public Health

Background:

  • Previous studies link cardiopulmonary resuscitation (CPR) quality to survival.
  • However, no large-scale study has compared CPR quality between resuscitation at the scene versus during transport.

Purpose of the Study:

  • To compare the proportion of out-of-hospital cardiac arrest (OHCA) resuscitations meeting all high-quality CPR benchmarks (chest compression fraction >0.7, rate >100/min, depth >5.0cm) between scene and transport phases.
  • To compare individual CPR quality metrics between the scene and transport phases.

Main Methods:

  • Analysis of CPR quality data from adult OHCA patients from January 2013 to April 2016.
  • Data sourced from the Rescu Epistry-cardiac arrest database.
  • Comparison of high-quality CPR achievement and individual metrics (compression rate, depth, chest compression fraction) between resuscitation occurring on scene versus during transport.

Main Results:

  • The proportion of patients receiving high-quality CPR was similar on scene (45.8%) versus during transport (42.5%).
  • Median compression rate was higher on scene (105.8 cpm) compared to transport (102.0 cpm).
  • Median compression depth (5.56cm vs. 5.33cm) and chest compression fraction (0.95 vs. 0.87) were higher during the transport phase.

Conclusions:

  • High-quality CPR metrics were comparable between scene and transport locations.
  • Results suggest prehospital providers can achieve high-quality manual compressions regardless of resuscitation location.

Cardiopulmonary Resuscitation I: Adult

Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
