Abstract

The present disclosure includes a pulse oximeter attachment having an accessible memory. In one embodiment, the pulse oximeter attachment stores calibration data, such as, for example, calibration data associated with a type of a sensor, a calibration curve, or the like. The calibration data is used to calculate physiological parameters of pulsing blood.

Claims (30)

1. A method for communicating a physiological waveform indicative of a physiological condition to a patient monitoring device, the method comprising:

obtaining a sensor signal indicative of a physiological parameter;

calculating a first physiological measurement using a first processor;

communicating the physiological measurement to a second processor;

outputting a physiological sensor signal from the second processor based on the calculated first physiological measurement; and

communicating the outputted physiological sensor signal to a patient monitoring device not associated with the first and second processors, the outputted physiological sensor signal configured to cause the patient monitoring device to calculate a second physiological measurement substantially equivalent to the first physiological measurement.

2. The method of claim 1 , further comprising displaying the calculated first physiological measurement on a first display associated with the first processor.

3. The method of claim 1 , wherein the physiological measurements comprise at least one of blood oxygen levels, blood pressure, ECG, and pulse rate.

4. The method of claim 1 , wherein the second processor comprises a waveform generator.

5. The method of claim 1 , wherein the second processor is housed within a docking station.

6. A system for communicating a physiological waveform indicative of a physiological condition to a patient monitoring device, the system comprising:

a sensor input configured to obtain a sensor signal indicative of a physiological parameter;

one or more processors configured to calculate a first physiological measurement and further configured to output a physiological signal based on the first physiological measurement; and

an output configured to communicate the physiological signal to a patient monitoring device not associated with the one or more processors, the physiological signal configured to cause the patent monitoring device to calculate a second physiological measurement substantially equivalent to the first physiological measurement.

7. The method of claim 6 , further comprising a first display in communication with the one or more processors, wherein the display is configured to display the calculated first physiological measurement.

8. The method of claim 6 , wherein the physiological measurements comprise at least one of blood oxygen levels, blood pressure, ECG, and pulse rate.

9. A method for communicating a physiological waveform indicative of a physiological condition to a patient monitoring device, the method comprising:

obtaining a first sensor signal indicative of a physiological parameter;

calculating a first physiological measurement based on the first sensor signal;

outputting a second sensor signal based on the first physiological measurement; and

communicating the second sensor signal to a patient monitoring device, the second sensor signal configured to cause the patient monitoring device to calculate a second physiological measurement substantially equivalent to the first physiological measurement;

wherein the patient monitoring device communicates with a second display.

10. The method of claim 9 , further comprising displaying a power on indication on a first display.

11. The method of claim 9 , further comprising displaying signal quality information on a first display.

12. The method of claim 9 , further comprising displaying the first physiological measurement on a first display.

13. A system for communicating a physiological waveform indicative of a physiological condition to a patient monitoring device, the system comprising:

a sensor input configured to obtain a first sensor signal indicative of a physiological parameter;

at least one processor configured to determine a first physiological measurement based on the first sensor signal and output a second sensor signal based on the first sensor signal; and

an output configured to communicate the second sensor signal to a patient monitoring device, the second sensor signal configured to be used by the patient monitoring device to calculate a second physiological measurement substantially equivalent to the first physiological measurement, wherein the patient monitoring device communicates with a second display.

14. The system of claim 13 , further comprising a first display.
