Claim:
1. A system configured to be supported by a subject, the system comprising: a processor; a physiological monitor comprising at least one light source arranged to interrogate a region of the subject and at least one photodetector arranged to receive radiation from the at least one light source that has been transmitted through or reflected from the interrogated region, the physiological monitor being configured to operate in a plurality of different monitoring modes in each of which the at least one light source and at least one photodetector are controlled to cause the physiological monitor to monitor a different set of one or more physiological parameters of the subject, wherein at least a first one of the plurality of monitoring modes monitors at least blood oxygenation of the subject and at least a second one of the plurality of monitoring modes monitors at least a physiological parameter selected from the group consisting of: blood glucose, plethysmography, and heart rate; and an activity monitor comprising an accelerometer; wherein the processor is configured to process data from the accelerometer to compute at least one metric for an activity being performed by the subject, and determine a monitoring mode, from among the plurality of monitoring modes, of the physiological monitor based upon the computed metric for the activity; wherein the physiological monitor is configured to receive a control signal from the processor that identifies the determined monitoring mode in which the physiological monitor is to operate, and is further configured to operate in the determined monitoring mode in response to the received control signal; and wherein each of the plurality of monitoring modes comprises a mode in which at least one physiological parameter of the subject is monitored based upon at least one measurement made by the physiological monitor while the physiological monitor is in the determined monitoring mode.
