Abstract
Embodiments of the present invention include systems and methods that relate to pulse oximetry. Specifically, one embodiment includes an oximeter sensor comprising a light emitting element configured to emit light, a light detector configured to detect the light, and a memory chip having a built-in trimmed resistor, the trimmed resistor having a resistance value that is detectable by a monitor.
Claims32
A device wearable by a patient, comprising:
- a sensor configured to collect sensor data from the patient;
- a processor configured to evaluate the sensor data and to generate physiological data based in least in part on the sensor data, wherein the physiological data comprises at least data representative of a physiological waveform;
- at least one memory configured to store the physiological data and one or more patient specific alarm limits, wherein the processor is configured to determine whether the physiological data exceeds the one or more patient specific alarm limits;
- and
- an interface configured to transmit at least some of the physiological data to a remote device, wherein the device is configured to operate independently from the remote device.
2 more elements
A device wearable by a patient, comprising:
- a pulse oximeter sensor configured to generate a signal indicative of an oxygen saturation measurement of the patient;
- a processor configured to evaluate the signal and to generate physiological data based on the signal;
- at least one memory configured to store the physiological data, the device configured wherein at least a portion of the physiological data is stored in the memory in response to the processor determining that the physiological data exceeds one or more alarm limits;
- and
- an interface configured to transmit at least some of the physiological data to a remote device, wherein the device is configured to operate independently from the remote device.
