Do manual chest compressions provide substantial ventilation during prehospital cardiopulmonary resuscitation?

Chest compressions have been suggested to provide passive ventilation during cardiopulmonary resuscitation. Measurements of this ventilatory mechanism only performed upon arrival out-of-hospital cardiac arrest patients in the emergency department. Lung and thoracic characteristics rapidly change following arrest, possibly limiting effectiveness after prolonged resuscitation efforts. Goal study was quantify inspiratory tidal volumes generated by manual chest compression prehospital A flowsensor used adult cases attended a medical team. Adult, endotracheally intubated, non-traumatic were eligible for inclusion. Immediately intubation, sensor connected endotracheal tube. The first thirty intubation (without simultaneous ventilation) calculated. 10 (5 female) included, median age 64 years (IQR 56, 77 years). frequency 111 per minute 107, 116 minute). depth 5.6 cm 5.4 cm, 6.1 cm). volume 20 mL 13, 28 mL).
