ALARM SUSPEND SYSTEM
First Claim
1. A noninvasive optical based physiological measurement system comprising:
- a plurality of light emitting diodes configured to transmit a plurality of wavelengths of light onto a tissue site of a patient;
at least one detector configured to measure an indication of the plurality of wavelengths of light after attenuation by tissue of the patient and output a signal indicative of the attenuated light;
one or more processors configured to receive the detector output signal and to determine a plurality of different physiological measurements, the one or more processors further configured to determine if an alarm threshold has been met and activate an alarm;
a speaker associated with the one or more processors, the speaker configured to generate an audible signal in response to the alarm activated by the one or more processors; and
a silence button associated with the one or more processors;
wherein, when the alarm is activated for at least one of the plurality of different physiological measurements and the silence button is activated by a user, the one or more processors deactivate the alarm for a period of time, the period of time being different for each different physiological measurement of the plurality of different physiological measurements.

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.

13. A physiological measurement system comprising:
-
a sensor configured to attach to a patient so as to transmit optical radiation into a tissue site and generate a sensor signal responsive to the optical radiation after attenuation by pulsatile blood flow within the tissue site; a monitor in communications with the sensor so as to measure a plurality of physiological parameters responsive to the sensor signal; a display mounted on the monitor that displays the measured parameters along with visual alarms associated with the measured parameters; a speaker mounted on the monitor that generates an audible alarm triggered by at least one of the parameters; a silence button mounted on the monitor that, when actuated, initiates a silence request for the monitor to suspend the audible alarm; and an alarm suspend system that deactivates the audible alarm for a parameter specific duration according to the alarm-triggering parameter. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
