Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter measuring characteristics of the airflows. A user may provide a controller with patient size information via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. If the measured airflow characteristics fall outside an acceptable range, the controller may cause a sensory alarm to alert the user. The device may work within a network of devices and user interfaces. The device may include a variety of sensors including pressure, CO
