System for determining confidence in respiratory rate measurements
First Claim
1. A system for monitoring parameters of a medical patient using signals received from physiological sensors associated with the medical patient, the system comprising:
- a memory device configured to store an alarm delay time and an alarm threshold;
a hardware processor in communication with the memory device, the hardware processor configured to;
monitor a physiological parameter reflecting physiological information obtained from a physiological sensor coupled to a medical patient, anddetermine whether the physiological parameter satisfies the alarm threshold for an amount of time corresponding to the alarm delay time;
a visible alarm or an audible alarm configured to be triggered in response to determining that the physiological parameter satisfies the alarm threshold for the amount of time corresponding to the alarm delay time; and
a display configured to output an indicator responsive to an amount of time that the physiological parameter satisfies the alarm threshold,wherein the indicator is a visible indicator that is responsive to a comparison of (i) the amount of time that the physiological parameter satisfies the alarm threshold and (ii) the alarm delay time, andwherein the visible indicator comprises (i) a count that depends on the comparison, (ii) a first alert having a display frequency that depends on the comparison, or (iii) a second alert having a display size that depends on the comparison.

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.
