Nuisance Alarm Reduction Method For Therapeutic Parameters
First Claim
1. A method for reducing nuisance alarms while monitoring one or more non-physiological parameters in a ventilatory system, the method comprising:
- receiving alarm conditions, wherein the alarm conditions include a parameter threshold and an integral threshold;
monitoring at least one parameter of the one or more non-physiological parameters;
detecting a breach of the parameter threshold;
calculating an integral of the breach; and
determining whether the integral of the breach is greater than the integral threshold.

Abstract
This disclosure describes systems and methods for reducing nuisance alarms associated with monitoring non-physiological parameters in a ventilatory system. Non-physiological parameters may include, but are not limited to, parameters that are internally monitored by the ventilator based on pre-configured ranges dictated by the manufacturer, by an applicable protocol, or by the clinician. Embodiments described herein seek to mitigate nuisance alarms by basing alarm conditions, at least in part, on an integral threshold such that an alarm is not generated when a monitored parameter briefly falls outside an acceptable range by a slight degree, but such that an alarm is generated when a monitored parameter falls outside an acceptable range by a more significant magnitude and/or duration.

8. A ventilatory system for reducing nuisance alarms while monitoring one or more non-physiological parameters, comprising:
-
at least one processor; and at least one memory, communicatively coupled to the at least one processor and containing instructions that, when executed by the at least one processor, perform a method comprising; receiving alarm conditions, wherein the alarm conditions include a parameter threshold and an integral threshold; monitoring at least one parameter of the one or more non-physiological parameters; detecting a first breach of the parameter threshold; calculating a first integral of the first breach; determining whether the first integral of the first breach is greater than the integral threshold; when the first integral of the first breach is not greater than the integral threshold, incrementally reducing the first integral of the first breach over a predetermined period of time; detecting a second breach of the parameter threshold; calculating a second integral of the second breach; and determining whether a sum of the incrementally reduced first integral plus the second integral is greater than the integral threshold. - View Dependent Claims (9, 10, 11, 12)

13. A graphical user interface for configuring alarm conditions that reduce nuisance alarms on a ventilator, the ventilator configured with a computer having a user interface including the graphical user interface for accepting commands, the graphical user interface comprising:
-
at least one window associated with the graphical user interface; one or more elements within the at least one window, comprising at least one of one or more input elements for enabling the clinician to input alarm settings for reducing nuisance alarms associated with monitoring one or more non-physiological parameters; and one or more selection elements for enabling the clinician to select one or more; graphic displays of data collected while monitoring the one or more non-physiological parameters, and preconfigured alarm settings for reducing nuisance alarms associated with monitoring the one or more non-physiological parameters. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
