Study Notes
CPR Techniques: A Comprehensive Overview
Cardiopulmonary resuscitation (CPR) is a critical lifesaving technique used to restore blood circulation and breathing in individuals experiencing cardiac arrest. Over the years, various CPR techniques and devices have been developed to improve resuscitation outcomes. In this article, we will discuss some of the most common CPR techniques and their implications.
High-Frequency Chest Compressions
High-frequency chest compressions involve compressions at a rate greater than 120 per minute. Some studies have shown that high-frequency chest compressions can improve hemodynamics compared to conventional chest compressions, but there is no change in clinical outcome reported. The 2010 AHA Guidelines for CPR and ECC recommend compressions at a rate of at least 100/min. High-frequency chest compressions may be considered by adequately trained rescue personnel as an alternative, but they are not recommended for routine use in cardiac arrest.
Open-Chest CPR
Open-chest CPR is a technique where the heart is accessed through a thoracotomy and compression is applied directly to the heart. One randomized controlled trial did not show any survival advantage to IAC-CPR in adult out-of-hospital cardiac arrest, but there were no complications reported in adults. However, there is insufficient evidence to recommend for or against the use of IAC-CPR in the out-of-hospital setting or in children.
"Cough" CPR
"Cough" CPR involves forceful voluntary coughs every 1 to 3 seconds in conscious patients shortly after the onset of a nonperfusing cardiac rhythm in a controlled environment. This technique can generate systemic blood pressures higher than those usually generated by conventional chest compressions, allowing patients to maintain consciousness for a brief arrhythmic interval. However, it is only useful for conscious, supine, and monitored patients in controlled environments such as the cardiac catheterization laboratory. "Cough" CPR should not delay definitive treatment and is not useful for unresponsive victims.
Prone CPR
When a patient cannot be placed in the supine position, it may be reasonable for rescuers to provide CPR with the patient in the prone position, particularly in hospitalized patients with an advanced airway in place. This technique may be considered in settings where the patient can be instructed and coached to cough forcefully every 1 to 3 seconds during the event, but it should not delay definitive treatment.
Precordial Thump
The 2010 Guidelines introduced a new technique called Precordial Thump, which is based on the conclusions reached by the 2010 ILCOR evidence evaluation process.
In conclusion, while high-frequency chest compressions and open-chest CPR may be considered by adequately trained personnel, they are not recommended for routine use. "Cough" CPR is useful only in specific settings and for conscious, supine, and monitored patients. Prone CPR may be considered when the patient cannot be placed in the supine position, and Precordial Thump is a new technique introduced in the 2010 Guidelines. It is essential for rescuers to be trained in these techniques and to provide CPR promptly in case of cardiac arrest.
