A medical system comprises a manual patient ventilation unit defining an airflow path. The unit 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 comprises a ventilation bag (212) configured to enable manual ventilation of the patient by a rescuer; an airflow sensor (204) in the airflow path positioned to sense the presence of ventilation airflow and measure a gas flow rate in the airflow path, a pressure sensor in the airflow path positioned to sense gas pressure in the airflow path, and 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. A feedback unit (208) provides feedback to a rescuer based on the one or more ventilation quality parameters. |
