Alarm suspend system
First Claim
1. A monitor having a sensor configured to attach to a person 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, the monitor configured to measure and display a plurality of physiological parameters responsive to the sensor signal and to generate alarms when those parameter measurements are outside of the predetermined limits, the monitor having an alarm suspend system for silencing the alarms, the alarm suspend system comprising:
- an alarm trigger responsive to any of a plurality of parameters and to predetermined limits corresponding to the parameters;
the parameters partitioned into a plurality of fast treatment parameters and a plurality of slow treatment parameters according to the relative length of time it takes for a person to respond to medical treatment for a parameter measurement outside of the predetermined limits;
an audible alarm responsive to the alarm trigger;
an alarm silence button actuated so as to suspend the audible alarm;
a timer for timing the duration of the suspended alarm;
the timer initiated by actuation of the alarm silence button;
the time retriggering the audible alarm after the timed duration has lapsed;
a long duration suspend time associated with the slow treatment parameters; and
a short duration suspend time associated with the fast treatment parameters.

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.

7. An alarm suspend method performed by a patient monitoring device, the method comprising:
-
measuring a plurality of physiological parameters using a patient monitoring device including a processor; partitioning, the parameters into at least a first group and a second group; triggering an audible alarm if at least one parameter is outside of predetermined limits; suspending the audible alarm in response to a silence request; associating a first duration with the first group and a second duration with the second group; setting the first duration so as to generally correspond to a first range of treatment times for the first group of parameters; setting the second duration so as to generally correspond to a second range of treatment times for the second group of parameters; the first range of treatment times and the second range of treatment times being non-overlapping; and reactivating the audible alarm after at least one of the first duration and the second duration. - View Dependent Claims (8, 9, 10, 11, 12)

13. A physiological measurement system comprising:
-
a sensor configured to attach to a person 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 communication 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; an alarm suspend system that deactivates the audible alarm for one of a short duration and a long duration according to the alarm-triggering parameter; a first group of parameters associated with the short duration; and a second group of parameters associated with the long duration; the first group and the second group partitioned according to a fast treatment time and a short treatment time associated with the parameters. - View Dependent Claims (14, 15, 16, 17, 18)
