System and method for monitoring respiratory rate measurements

A physiological computing system configured to measure a respiratory rate of a user, the system comprising:

• an acoustic sensor configured to generate an acoustic signal from monitoring a patient;
• an optical sensor configured to generate a photoplethysmographic signal from monitoring the patient;
• one or more hardware processors configured to:
• receive the acoustic signal from the acoustic sensor and the photoplethysmographic signal from the optical sensor;
• determine a first respiratory rate measurement for the patient from the acoustic signal and a second respiratory rate measurement for the patient from the photoplethysmographic signal;
• determine a combined respiratory rate measurement for the patient from the first respiratory rate measurement and the second respiratory rate measurement;
• and
• output the combined respiratory rate measurement;
• and
• a display configured to present the combined respiratory rate measurement.

A physiological monitoring method for measuring a respiratory rate of a user, the method comprising:

• generating, by an acoustic sensor, an acoustic signal from monitoring the user;
• generating, by an optical sensor, a photoplethysmographic signal from monitoring the user;
• determining, by one or more hardware processors, a first respiratory rate measurement for the user from the acoustic signal and a second respiratory rate measurement for the user from the photoplethysmographic signal;
• determining, by the one or more hardware processors, a combined respiratory rate measurement for the user from the first respiratory rate measurement and the second respiratory rate measurement;
• and
• presenting, by a display, the combined respiratory rate measurement;
