Mouth to mouth ventilation does not improve CPR
When performed by a bystander, cardiopulmonary resuscitation (CPR) with chest compression alone provides similar survival to standard CPR with chest compression plus mouth to mouth ventilation in sudden cardiac arrest, according to a new study.
Researchers at the University of Washington, in Seattle, compared the outcome of 520 cases of cardiac arrest outside hospital. In each case, a bystander was randomised to receive telephone instructions by a fire department dispatcher, who provided either standard CPR instructions with mouth to mouth ventilation or instructions for chest compression alone. Instructions for compression took only 1.4 minutes less than instructions for compression plus mouth to mouth breathing, the report indicates.
Overall, 64 patients, 29 (10.4%) in the mouth to mouth breathing group and 35 (14.6%) in the chest compression only group, survived to hospital discharge, the authors report. This difference was not significant, and adjustment of the results for the patient's age, race,
