1. A medical device configured to receive a physiological signal from a physiological sensor coupled with a patient and to perform a spot-check measurement based on the physiological signal, the medical device comprising:
a driver circuit that drives one or more emitters of a physiological sensor at multiple wavelengths of light to cause the one or more emitters to transmit the multiple wavelengths of light through body tissue of a patient;
a hardware processor in communication with the physiological sensor, the hardware processor configured to:
process the physiological signal to calculate a first plurality of physiological parameter values;
output the physiological parameter values to a display;
detect a snapshot condition comprising at least one of:
a determination that the physiological sensor has been disconnected from the patient; or
a user input to select a snapshot of the physiological signal; and
upon detecting the snapshot condition,
select a currently-displayed physiological parameter value of the first plurality of physiological parameter values as the first spot-check measurement;
freeze the selected currently-displayed physiological parameter value on the display;
stop processing the physiological signal to calculate the first plurality of physiological parameter values from the physiological signal; and
output the first spot-check measurement to a speaker or the display.
 
10. A method for using a medical device to perform a spot-check measurement, the method comprising:
by a medical device comprising electronic hardware:
receiving a physiological signal from a sensor coupled with a patient;
processing the physiological signal to calculate a plurality of first values of a first physiological parameter and a plurality of second values of a second physiological parameter;
detecting a snapshot condition comprising at least one of:
a determination that the sensor has been disconnected from the patient; or
a user input to select a snapshot of the physiological signal;
selecting one of the first values as a first spot-check measurement and one of the second values as a second spot-check measurement upon detecting the snapshot condition;
stopping processing the physiological signal to calculate, from the physiological signal, the first plurality of physiological parameter values; and
calculating a contributor score for each of the first spot-check measurement and the second spot-check measurement;
determining an early warning score based at least in part on the contributor scores; and
outputting, audibly or to a display, at least the early warning score.
