Pulmonary barotrauma during cardiopulmonary resuscitation

Two cases are presented of pulmonary barotrauma developing during cardiopulmonary resuscitation. This was attributed to high airway pressures developed during ventilation. One patient was ventilated with a self-inflating bag and the second with the Robertshaw demand valve. Both devices were used appropriately. Three other cases of pulmonary barotrauma during resuscitation have been recorded with the use of the latter device during CPR by ambulance personnel in Israel. The Robertshaw demand valve may generate excessively high airway pressures during normal use or when malfunctioning. For these reasons, the use of the Robertshaw demand valve has been discontinued in the Israeli Emergency Medical Services ambulances.
