Abstract
A medical system includes a manual patient ventilation unit defining an airflow path arranged so that when the unit is applied to a patient the airflow path is in fluid communication with the patient's airway. The patient ventilation unit includes a ventilation bag configured to enable manual ventilation of the patient by a rescuer, an airflow sensor in the airflow path positioned to sense the presence of ventilation airflow and measure a gas flow rate in the airflow path, and a pressure sensor in the airflow path positioned to sense gas pressure in the airflow path. The system also includes a processor arranged to receive data generated by the airflow sensor and the pressure sensor and determine one or more ventilation quality parameters based at least in part on a gas flow volume calculated based on the sensed gas flow rate and gas pressures.
