Mouth-to-Mouth May Not Save More Lives During CPR, Studies Show

Hollywood heroics aside, mouth-to-mouth resuscitation does nothing to improve the outcome of CPR, two studies showed. It doesn’t provide any benefit over the chest-pumping procedure, U.S. and Swedish scientists said.

In the research, there was no significant difference in survival for patients who received just chest-compression CPR from bystanders after heart stoppages compared with those who got both that treatment and mouth-to-mouth breathing, according to two papers published today in the New England Journal of Medicine.
