Abstract

Systems and method for monitoring patient physiological data are presented herein. A gas analyzing measurement head can be provided to sample and analyze respiratory gases of a patient. In one embodiment, the gas analyzing measurement head can read information on an information element of an airway adapter or resuscitation bag. Such information can be used to generate instructions for manual ventilation using the gas analyzing measurement head, airway adapter, and resuscitation bag. Manual ventilation instructions can be displayed on the gas analyzing measurement head or can be transmitted for display on another device, such as a clinician'"'"'s mobile computing device.
