Abstract
This disclosure describes, among other features, systems and methods for using multiple physiological parameter inputs to determine multiparameter confidence in respiratory rate measurements. For example, a patient monitoring system can programmatically determine multiparameter confidence in respiratory rate measurements obtained from an acoustic sensor based at least partly on inputs obtained from other non-acoustic sensors or monitors. The patient monitoring system can output a multiparameter confidence indication reflective of the programmatically-determined multiparameter confidence. The multiparameter confidence indication can assist a clinician in determining whether or how to treat a patient based on the patient'"'"'s respiratory rate.

21. A system for monitoring a respiratory rate measurement from a patient, the system comprising:
-
one or more hardware processors configured to; receive an acoustic signal generated by an acoustic sensor responsive to vibrations of a patient, determine, from the acoustic signal, a first measurement of a respiratory rate, determine a first range of measurements of the respiratory rate from one or more characteristics of the patient, the first range of measurements forming a first safety zone, and determine a second range of measurements of the respiratory rate from the one or more characteristics, the second range of measurements forming a second safety zone, the second range of measurements being different from the first range of measurements and representing a greater safety risk to the patient than the first range of measurements; and a display configured to present the first safety zone and the second safety zone together with an indicator, the indicator being positioned according to the first measurement, a position of the indictor relative to the first safety zone and the second safety zone denoting whether the first measurement is within the first range of measurements or the second range of measurements and denoting a degree of safety concern for the patient estimated from the first measurement. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
