Automatic Ventilation in Prehospital Resuscitation on OHCA

"The FDA-approved device used is Meditech MICROVENT RESUSCITATOR, which is connected to the endotracheal tube, supraglottic airway or tracheostomy tube. It is powered by the airflow from the oxygen tank and provides ventilation in fixed interval. It has a pressure valve which will release the pressure once the airway pressure exceeds its threshold. In the current study, the threshold is set at 60 mmH2O. The tidal volume is set at 500-600 ml."

The adult size bag-valve mask is connected to the endotracheal tube, supraglottic airway or tracheostomy tube. The interval, pressure and volume of the ventilation is controlled by the emergency medical technicians.
