Abstract: 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 for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user. The device may suggest a corrective action based on the type of off-target ventilation detected. The device may also continuously analyze ventilation to determine changes in lung compliance over time and to identify pathological changes over time. The device may work within a network of devices and user interfaces via wired or wireless communication, and is not restricted to or dependent on the type of ventilatory device with which a patient is being supported.

Abstract: 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, CO2, O2, and temperature sensors. If the measurements of these sensors fall outside an acceptable range, the controller may cause a sensory alarm to alert the user.
