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 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; and a hardware processor in communication with the memory device, the hardware processor configured to; monitor a first physiological parameter reflecting first physiological information obtained from a first physiological sensor coupled to a medical patient, determine whether the first physiological parameter satisfies the alarm threshold for an amount of time corresponding to the alarm delay time, trigger an alarm in response to determining that the first physiological parameter satisfies the alarm threshold for the amount of time corresponding to the alarm delay time, monitor a second physiological parameter reflecting second physiological information associated with the medical patient, the second physiological parameter being different from the first physiological parameter, and automatically adjust the alarm delay time based at least on the second physiological parameter. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
