Mouth-to-mouth resuscitation is effective even when “performed with the FFP2 mask”. Here is the study.
The researchers also used an app to measure the volume of air breathed in the mannequins.
A particular but important study. Mouth-to-mouth respiration is also effective when performed with the FFP2 mask. This is demonstrated by a study by Masaryk University (Czech Republic) presented at the annual meeting of the European Society of Anesthesiology and Intensive Care, which closes today in Milan. The researchers conducted an experiment with the help of 104 medical students to verify if it was possible, in times of Covid-19, to perform the maneuver effectively even with the use of a mask to reduce the risk of contagion. The students were then asked to perform mouth-to-mouth ventilation for two minutes on three manikins (two adult mannequins, adult BLS manikin and Resusci Anne, and one child manikin, Resusci Baby).
More than 90% of the breaths delivered into each manikin’s mouth were judged to be effective, meaning they caused the manikin’s chest to rise. Notably, breaths were 96.9% effective with the adult BLS manikin, 90.7% with the Resusci Anne, and 95.7% with the Resusci Baby. The researchers also used an app to measure the volume of air breathed in the Resusci Anne and Resusci Baby mannequins. Volume was optimal in 33% of Resusci Anne breaths and in 44% of Resusci Baby breaths. Breaths were below optimal volume in 28.9% of cases with the Resusci Anne and in 15.9% of cases with the Resusci Baby, while it was above optimal in 28.8% and 35, respectively. 8% of cases.
