System for determining confidence in respiratory rate measurements
First Claim
1. A method of triggering an alarm based on information related to a physiological parameter, the method comprising:
- by a processor;
providing functionality for a clinician to specify an alarm delay time;
monitoring a first physiological parameter reflecting physiological information obtained from a physiological sensor coupled to a patient, the first physiological parameter comprising respiratory rate;
determining whether the first physiological parameter has satisfied an a first alarm threshold for an amount of time corresponding to the alarm delay time;
triggering an alarm in response to said determining that a value of the first physiological parameter has satisfied the first alarm thresholdmonitoring a second physiological parameter, the second physiological parameter comprising oxygen saturation;
determining whether the second physiological parameter has fallen below a second alarm threshold;
automatically reducing the alarm delay time in response to the second physiological parameter having fallen below the second alarm threshold; and
modifying a display of a confidence indicator based on the amount of time that the first physiological parameter has satisfied the first alarm threshold.

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.

4. A method of triggering an alarm based on information related to a physiological parameter, the method comprising:
by a processor; monitoring a first physiological parameter reflecting physiological information obtained from a physiological sensor coupled to a patient, the first physiological parameter comprising respiratory rate; automatically adjusting an alarm delay threshold for the first physiological parameter based on a value of a second physiological parameter, the second physiological parameter comprising oxygen saturation, wherein said adjusting comprises reducing the alarm delay threshold in response to the value of the second physiological parameter meeting a first threshold; determining whether the first physiological parameter has satisfied a second threshold for an amount of time corresponding to the alarm delay threshold; and triggering an alarm in response to said determining that a value of the first physiological parameter has satisfied the second threshold for the amount of time corresponding to the alarm delay threshold. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
