Smart medical device management

A smart bag-valve mask device, comprising:

• a mask configured to be in contact with a face of a patient;
• a bag fluidly connected to the mask, the mask and the bag enclosing a space that is fluidly connected to an airway of the patient;
• a first sensor configured to detect a flow of air in the space;
• a second sensor configured to detect a pressure in the space;
• a display configured to visually output an air flow waveform representing the flow of air over time, and an air pressure waveform representing the pressure over time;
• and
• a processor configured to:
• determine a first ventilation volume by analyzing the flow of air during a first ventilation occurring when the bag is contracted and released a first time;
• determine a second ventilation volume by analyzing the flow of air during the second ventilation occurring when the bag is contracted and released a second time;
• identify a first ratio between the first ventilation volume and the pressure during the first ventilation;
• identify a second ratio between the second ventilation volume and the pressure during the second ventilation;
• determine a discrepancy between the first ratio and the second ratio;
• in response to determining the discrepancy between the first ratio and the second ratio, determine that a leak is present between the mask and the face of the patient;
• and
• cause the display to output an alert indicating that the leak is present.

A medical device, comprising:

• an airway adaptor configured to be connected to an airway of a patient;
• a first sensor configured to detect a first parameter of a space fluidly connected to the airway adaptor;
• a second sensor configured to detect a second parameter of the space;
• a display;
• and
• a processor configured to:
• determine a first relationship between the first parameter and the second parameter during a first ventilation;
• determine a second relationship between the first parameter and the second parameter during a second ventilation;
• determine a discrepancy between the first relationship and the second relationship;
• based on determining the discrepancy, identify a leak between the airway adaptor and the airway of the patient;
• generate an alert indicating the leak;
• and
• cause the display to output the alert.

A method, comprising:

• detecting a first parameter of a space in a bag-valve mask that is fluidly connected to an airway of a patient and that is disposed on a face of the patient;
• detecting a second parameter of the space;
• identifying a first relationship between the first parameter and the second parameter during a first ventilation;
• identifying a second relationship between the first parameter and the second parameter during a second ventilation;
• determining a discrepancy between the first relationship and the second relationship;
• based on determining the discrepancy between the first relationship and the second relationship, identifying a leak between the bag-valve mask and the face of the patient;
• and
• based on identifying the leak, outputting an alert indicating the leak.
