System, device, and arrangement for a manual ventilation assistant

A device, comprising:

• an air filter, of a coupling of the device, configured to be positioned within an airway of a manual ventilator;
• a differential pressure sensor configured to provide a differential pressure measurement associated with a differential pressure across the air filter via a first sensor line and a second sensor line;
• and
• an absolute pressure sensor configured to measure an absolute pressure of a patient airway near or toward a patient-side opening via a third sensor line;
• and
• a monitor configured to:
• receive information indicating a differential pressure measurement and an absolute pressure measurement from the differential pressure sensor and the absolute pressure sensor, respectively;
• determine, based on the information indicating the differential pressure measurement and the absolute pressure measurement, an air flow rate through the airway;
• determine, based on the air flow rate and a flow threshold, whether a compression parameter of the manual ventilator requires adjustment,
• wherein the monitor, when determining whether the compression parameter requires adjustment, is configured to:
• determine a desired breathing cycle based on one or more characteristics of the device,
• determine a timing of a patient breathing cycle facilitated by the manual ventilator, and
• determine the flow threshold based on the timing and the desired breathing cycle;
• and
• provide, via a display associated with the manual ventilator, an indication associated with whether the compression parameter requires adjustment.

A manual ventilation system comprising:

• a manual ventilator including a ventilator airway and a patient-side opening,
• wherein the patient-side opening is configured to fluidly couple the ventilator airway with a patient airway;
• a manual ventilator assistant, separate from the manual ventilator and configured to assist a user in using the manual ventilator, including a coupling, a differential pressure sensor, an absolute pressure sensor, a first sensor line, a second sensor line, and a third sensor line,
• wherein the coupling includes an air filter and is configured to be fluidly coupled to the manual ventilator,
• wherein the differential pressure sensor is configured to measure a differential pressure across the air filter via the first sensor line and the second sensor line, and
• wherein the absolute pressure sensor is configured to measure an absolute pressure of the patient airway near or toward the patient-side opening via the third sensor line;
• a ventilation monitor configured to:
• receive information indicating a differential pressure measurement and an absolute pressure measurement from the differential pressure sensor and the absolute pressure sensor, respectively;
• determine, based on the information indicating the differential pressure measurement and the absolute pressure measurement, an air flow rate through the ventilator airway,
• determine a desired breathing cycle based on one or more characteristics of the manual ventilation system;
• and
• provide, via a display associated with the manual ventilator, an indication associated with the air flow rate and based on the desired breathing cycle.
