Interruption of Compressions

چکیده
To begin to answer the question of whether ventilations are needed during cardiopulmonary resuscitation (CPR), Part I of this newsletter published in September showed that ventilations during cardiac arrests are not performed according to the American Heart Association (AHA) Guidelines. The high rates of ventilation increase intrathoracic pressure, decrease cardiac output and coronary perfusion pressure, and are related to poor survival. Several methods were suggested to coach providers in the delivery of the correct rate of ventilations. Gasping is common early in cardiac arrest, contributes to increased coronary and cerebral perfusion pressure, and is associated with an improved survival. But the presence of gasping confuses many rescuers and leads to CPR being withheld.

LUCAS-2 in Out-of-Hospital Cardiac Arrest: Cost Analysis
A critical step of the resuscitation process is early cardiopulmonary resuscitation (CPR) – i.e., the combination of chest compressions and ventilations. CPR can be started by bystanders and is typically taken over by emergency services. Current resuscitation guidelines highlight the importance of high-quality CPR for ensuring optimal outcomes from cardiac arrest. In this context, several mecha...

Many of the changes in BLS recommended in 2005 Guidelines are designed to simplify CPR recommendations, increase the number and quality of chest compressions delivered, and increase the number of uninterrupted chest compressions. The recommendations for compressions have been summarized as, "Push harder, push faster, allow the chest to fully recoil, and stop only to use a bag mask to ventilate ...

BACKGROUND Recent guidelines for infant cardiopulmonary resuscitation emphasize that all rescuers should minimize interruption of chest compressions, even for endotracheal intubation. We compared the utility of the Pentax-AWS Airwayscope (AWS) with the Glidescope (GS) during chest compressions on an infant manikin. METHODS Twenty-four anesthesiologists with more than two years of experience p...

T he importance of closed-chest compression in maintaining at least a minimum of myocardial blood flow during cardiac arrest has been increasingly recognized. The adverse effect of interruptions of chest compressions on coronary perfusion pressure is immediate and important; Berg et al showed a 40% decrease in cumulative coronary perfusion after a 13-second pause in chest compression. The 2010 ...
متن کاملDuration of ventilations during cardiopulmonary resuscitation by lay rescuers and first responders: relationship between delivering chest compressions and outcomes.
BACKGROUND The 2010 guidelines for cardiopulmonary resuscitation allow 5 seconds to give 2 breaths to deliver sufficient chest compressions and to keep perfusion pressure high. This study aims to determine whether the recommended short interruption for ventilations by trained lay rescuers and first responders can be achieved and to evaluate its consequence for chest compressions and survival. ...
متن کاملReoxidation Rate of Sponge Iron Pellets, Briquettes and Iron Powder Compressed to Various Compressions in Air
The reoxidation rate of sponge iron pellets and briquettes and oxidation of pure iron powder with compressibility between 27% and 55% in air and within the temperature range 300-900°C has been investigated. Factors affecting the oxidation rate are presented. These include the effect of temperature, compressibility, and sintering of Fe-powder before and during the oxidation.
