Abstract

Systems and methods for correlating diagnostic readings obtained by at least two medical devices can include a pressure offset correction parameter that is calculated for the purpose of correlating oscillometric blood pressure readings between a “home” blood pressure monitor and an “office” blood pressure monitor. The offset correction parameter is used to adjust blood pressure readings of the “home” or “office” blood pressure monitor such that these readings can be validly compared with blood pressure readings obtained using the other blood pressure monitor. In this manner, a more complete and reliable blood pressure trend may be developed and used for managing blood pressure related medical conditions.

Claims

1. A method for correlating diagnostic measurements obtained by at least two different medical devices, the method comprising:

obtaining a first diagnostic measurement at a location on a patient by initiating a first oscillometric blood pressure measurement reading with a first medical device using a first inflatable cuff inflated to a pressure exceeding a systolic arterial pressure;

obtaining configuration data of the first medical device, the configuration data including set-up information and pneumatic information;

configuring a second medical device based on the configuration data of the first medical device;

obtaining a second diagnostic measurement at the same location on the patient by initiating a second oscillometric blood pressure measurement reading with the second medical device using the first inflatable cuff or a second inflatable cuff inflated to the pressure exceeding the systolic arterial pressure;

generating, by a processing unit, a correction parameter by comparing the first and second diagnostic measurements, wherein the correction parameter includes a pressure offset correction parameter that quantifies a difference in oscillometric blood pressure measured by the first medical device and the second medical device;

storing the correction parameter in the second medical device;

obtaining, by the second medical device, a blood pressure measurement; and

adjusting the blood pressure measurement using the correction parameter by offsetting the blood pressure measurement by the pressure offset correction parameter.

2. The method of claim 1, wherein the first diagnostic measurement is a first blood pressure value and the second diagnostic measurement is a second blood pressure value.

3. The method of claim 2, further comprising mechanically coupling the first medical device and the second medical device.

4. The method of claim 3, further comprising approximately simultaneously calculating, by the processing unit, the first and second blood pressure values.

5. The method of claim 4, further comprising calculating, by the processing unit, the first and second blood pressure values from the first and second oscillometric blood pressure measurement readings.

6. The method of claim 2, further comprising calculating, by the processing unit, the first blood pressure value from the first oscillometric blood pressure measurement reading.

7. The method of claim 6, further comprising wirelessly transmitting the first blood pressure value and the first oscillometric blood pressure measurement reading to the second medical device.

8. The method of claim 7, further comprising calculating, by the processing unit, the second blood pressure value from the second oscillometric blood pressure measurement reading.

9. The method of claim 2, further comprising transferring, by the processing unit, at least the first blood pressure value and the second blood pressure value to a web portal from the second medical device.

10. The method of claim 9, further comprising generating, by the processing unit, a blood pressure trend plot including at least the first blood pressure value and the second blood pressure value.
