Patient monitoring system

1. A method of determining one or more blood pressure measurements, the method comprising:

receiving, by a patient monitor in communication with an inflatable cuff configured to encompass a limb of a patient, a set of inflatable cuff configuration parameters;

determining, by a hardware processor of the patient monitor, a first blood pressure of the patient based at least in part on an inflated pressure inside the inflatable cuff;

assigning, by the hardware processor of the patient monitor, a confidence level to the first blood pressure based on the inflatable cuff configuration parameters;

determining, by the hardware processor of the patient monitor, whether the confidence level satisfies a threshold confidence level; and

based at least in part on a determination that the confidence level does not satisfy the threshold confidence level:

determining, by the hardware processor patient monitor, a second blood pressure of the patient based at least in part on a deflated pressure inside the inflatable cuff, and

causing a display to display at least one of the first blood pressure or the second blood pressure.

2. The method of claim 1 , wherein the inflated pressure comprises pressure inside the inflatable cuff during inflation.

3. The method of claim 1 , wherein the deflated pressure comprises pressure inside the inflatable cuff during deflation.

4. The method of claim 1 , wherein said determining the first blood pressure comprises:

inflating the inflatable cuff;

receiving a first data signal indicative of the inflated pressure inside the inflatable cuff;

filtering the first data signal;

identifying a maximum magnitude of the filtered first data signal; and

associating a pressure of the inflatable cuff at the identified maximum magnitude with a first systolic pressure.

5. The method of claim 1 , wherein said determining the second blood pressure comprises:

deflating the inflatable cuff;

receiving a second data signal indicative of the inflated pressure inside the inflatable cuff;

filtering the second data signal;

identifying a maximum magnitude of the filtered second data signal during the deflation of the inflatable cuff, a maximum slope of the filtered second data signal prior to the maximum magnitude, and a maximum slope of the filtered second data signal following the maximum magnitude; and

associating a pressure of the inflatable cuff at the identified maximum slope of the filtered second signal prior to the maximum magnitude with a second systolic pressure.

6. The method of claim 1 , wherein the inflatable cuff is configured to inflate using a replaceable gas reservoir or a portable inflation system.

7. The method of claim 6 , further comprising:

determining whether pressure within the replaceable gas reservoir satisfies a threshold pressure level; and

upon determining the replaceable gas reservoir does not satisfy the threshold pressure level, causing the display to display a notification.

8. The method of claim 6 , further comprising causing the display to display a waveform of at least one of a first data signal associated with the first blood pressure or a second data signal associated with the second blood pressure.

9. The method of claim 6 , further comprising determining the confidence level of the first blood pressure based on an amount and magnitude of noise observed in a first data signal associated with the first blood pressure.

10. The method of claim 6 , further comprising communicating with electronics of the replaceable gas reservoir.

11. The method of claim 10 , wherein the electronics indicate whether the replaceable gas reservoir is authorized.

12. The method of claim 10 , wherein the electronics associated with the gas reservoir indicate reservoir characteristics.

13. The method of claim 10 , wherein the electronics indicate usage of the replaceable gas reservoir.

14. The method of claim 13 , wherein updated data responsive to usage of the replaceable gas reservoir is written to the electronics of the replaceable gas reservoir.

15. A method of determining one or more blood pressure measurements, the method comprising:

receiving, by a processor, one or more inflatable cuff configuration parameters;

determining a first blood pressure during inflation of an inflatable cuff configured to encompass a limb of a monitored patient;

assigning a confidence level, by the processor, to the first blood pressure based at least in part on the one or more configuration parameters;

based at least in part on a determination that the confidence level does not satisfy a threshold confidence level: determining a second blood pressure during deflation of the inflatable cuff, and

causing a display to display at least one of the first blood pressure or the second blood pressure.

16. The method of claim 15 , further comprising inflating the inflatable cuff using a replaceable gas reservoir or a portable inflation system.

17. The method of claim 16 , further comprising communicating with electronics of the replaceable gas reservoir.
