Abstract
An application identification sensor comprises a plurality of emitters configured to transmit light into a tissue site and a detector configured to receive the light after tissue absorption. The detector generates a signal responsive to the intensity of the light and communicates the signal to a monitor. An information element is readable by the monitor so as to identify a sensor application. The monitor presets at least one user-selectable operational parameter in response to the information element.
Claims9
A patient monitoring device configurable for differing operational conditions, said device comprising:
- a physiological signal input configured to receive a physiological signal from a noninvasive optical sensor, said physiological signal indicative of one or more physiological parameters of a patient being monitored;
- a signal processing device configured to process said physiological signal and to determine values of said one or more physiological parameters, said processing of said physiological signal including accessing a plurality of configurable processing parameters, at least some of said configurable processing parameters affecting a sensitivity of said processing to changes in said physiological signal, the patient monitoring device being configurable to operate in a first configuration and a second configuration, wherein said sensitivity is greater in the second configuration than in the first configuration;
- and
- a single caregiver-actuated emergency care input that, when actuated a single time, causes the patient monitoring device to operate in the second configuration and electronically adjusts a plurality of said at least some configurable processing parameters to increase said sensitivity for emergency care situations.
A method of configuring a patient monitor based at least in part on an environment of use of said patient monitor, the method comprising:
- receiving electronic signals indicative of one or more physiological parameters of a monitored patient, said electronic signals indicative of light attenuated by body tissue of a monitored patient;
- receiving a single caregiver input indicative of a current patient monitoring environment, wherein a single actuation of said caregiver input causes a patient monitor to transition between a first configuration and a second configuration, wherein the first second configuration is associated with increased processing sensitivity as compared to the first configuration, and wherein said single actuation electronically adjusts a plurality of configurable processing parameters;
- and
- processing with a signal processor said electronic signals according to said caregiver input to determine output measurements for said one or more physiological parameters of said monitored patient,
- wherein a sensitivity of said processing is responsive to said plurality of configurable processing parameters.
