Alarm suspend system
First Claim
1. A physiological measurement system comprising:
- a physiological sensor including;
a plurality of light emitting diodes configured to transmit wavelengths of light onto a tissue site of a patient; and
at least one detector configured to measure an indication of the wavelengths of light after attenuation by tissue of the patient and output a signal responsive of the attenuated light;
one or more processors in communication with the physiological sensor, the one or more processors configured to;
determine a measurement of a physiological parameter based on the signal;
in response to determining an alarm activation threshold has been satisfied by the physiological parameter measurement, activate an alarm;
in response to a silence request by a user, suspend the alarm for a parameter-specific period of time; and
before expiration of the parameter-specific period of time, and in response to determining the physiological parameter measurement no longer satisfies the alarm activation threshold, deactivate the suspended alarm.

Abstract
An alarm suspend system utilizes an alarm trigger responsive to physiological parameters and corresponding limits on those parameters. The parameters are associated with both fast and slow treatment times corresponding to length of time it takes for a person to respond to medical treatment for out-of-limit parameter measurements. Audible and visual alarms respond to the alarm trigger. An alarm silence button is pressed to silence the audible alarm for a predetermined suspend time. The audible alarm is activated after the suspend time has lapsed. Longer suspend times are associated with slow treatment parameters and shorter suspend times are associated with fast treatment parameters.

18. A physiological measurement system comprising:
-
a physiological sensor means for outputting a signal responsive to a noninvasive measurement of attenuated light transmitted through a tissue site of a patient; and a processing means in communication with the physiological sensor means and configured to; determine a measurement of a physiological parameter based on the signal; in response to determining an alarm activation threshold has been satisfied by the physiological parameter measurement, activate an alarm; in response to a silence request by a user, suspend the alarm for a parameter-specific period of time; and before expiration of the parameter-specific period of time, and in response to determining the physiological parameter measurement no longer satisfies the alarm activation threshold, deactivate the suspended alarm. - View Dependent Claims (19, 20)
