Mouth-to-mouth ventilation does not improve CPR

The composition of gas given by mouth-to-mouth ventilation during CPR.

STUDY OBJECTIVE To compare the concentration of a rescuer's exhaled O2 and CO2 during mouth-to-mouth ventilation with or without chest compression. DESIGN Prospective repeated measures study. Simulated one- and two-rescuer cardiopulmonary resuscitation (CPR) was performed as recommended by the American Heart Association. SETTING University laboratory. PARTICIPANTS Fifty-five healthcare pr...

Retention of mouth-to-mouth, mouth-to-mask and mouth-to-face shield ventilation.

BACKGROUND Retention of mouth-to-mouth, mouth-to-mask and mouth-to-face shield ventilation techniques is poorly understood. METHODS A prospective randomised clinical trial was undertaken in January 2004 in 70 candidates randomly assigned to training in mouth-to-mouth, mouth-to-mask or mouth-to-face shield ventilation. Each candidate was trained for 10 min, after which tidal volume, respirator...

Mouth-to-mouth ventilation during cardiopulmonary resuscitation: word of mouth in the street versus science.

I n this issue of Anesthesia & Analgesia, Oschatz et al. (1) report that when lay bystanders in Vienna, Austria performed mouth-to-mouth ventilation in cardiac arrest victims before professional paramedics administered advanced cardiac life support, serious ventilation-related adverse effects such as pulmonary aspiration occurred no more often than in patients who collapsed in the presence of p...

Does rinsing the mouth before expectoration improve sputum specimen quality?

Carbohydrate mouth rinse: does it improve endurance exercise performance?

It is well known that carbohydrate (CHO) supplementation can improve performance in endurance exercises through several mechanisms such as maintenance of glycemia and sparing endogenous glycogen as well as the possibility of a central nervous-system action. Some studies have emerged in recent years in order to test the hypothesis of ergogenic action via central nervous system. Recent studies ha...
