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 by a first medical device;

obtaining a second diagnostic measurement by a second medical device;

generating a correction parameter by comparing the first and second diagnostic measurements; and

adjusting one of the first diagnostic measurement and the second diagnostic measurement using the correction parameter to correlate the second diagnostic measurement to the first diagnostic measurement.

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 initiating an oscillometric blood pressure measurement with the first medical device.

5. The method of claim 4, further comprising approximately simultaneously calculating the first and second blood pressure values.

6. The method of claim 5, further comprising calculating the first and second blood pressure values from a single set of oscillometric blood pressure data.

7. The method of claim 2, further comprising calculating the first blood pressure value from a set of oscillometric blood pressure data.

8. The method of claim 7, further comprising wirelessly transmitting the first blood pressure value and the set of oscillometric blood pressure data to the second medical device.

9. The method of claim 8, further comprising calculating the second blood pressure value from the set of oscillometric blood pressure data.

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

11. The method of claim 10, further comprising generating a blood pressure trend plot including at least the first blood pressure value the second blood pressure value.

12. A method for correlating blood pressure values obtained by a first blood pressure device and a second blood pressure device, the method comprising:

calculating a first blood pressure value with the first blood pressure device;

calculating a second blood pressure value with the second blood pressure device;

comparing the first and second blood pressure values and generating a correction value representing a difference between the first and second blood pressure values; and

modifying the second blood pressure value using the correction value to correlate the first and second blood pressure values.

13. The method of claim 12, further comprising mechanically coupling the first blood pressure device and the second blood pressure device.

14. The method of claim 13, further comprising:

initiating an oscillometric blood pressure measurement with the first blood pressure device; and

approximately simultaneously calculating the first and second blood pressure values.

15. The method of claim 14, further comprising calculating the first and second blood pressure values from a single set of oscillometric blood pressure data.

16. The method of claim 12, further comprising calculating the first blood pressure value from a set of oscillometric blood pressure data.

17. The method of claim 16, further comprising wirelessly transmitting the first blood pressure value and the set of oscillometric blood pressure data to the second blood pressure device.

18. The method of claim 17, further comprising calculating the second blood pressure value from the set of oscillometric blood pressure data.

19. The method of claim 18, further comprising:

transferring at least the first blood pressure value and the second blood pressure value to a web portal from the second blood pressure device; and

generating a blood pressure trend plot including at least the first blood pressure value the second blood pressure value.

20. A computer-implemented method for correlating blood pressure values obtained by two blood pressure devices, the method comprising:

calculating a first blood pressure value from a set of oscillometric blood pressure data obtained by an office blood pressure device, the office blood pressure device being configured for use in a doctor'"'"'s office;

calculating a second blood pressure value with a home blood pressure device from the set of oscillometric blood pressure data obtained by the office blood pressure device, the home blood pressure device being configured for use in a patient'"'"'s personal home;

comparing the first and second blood pressure values;

generating a correction value representing a difference between the first and second blood pressure values;

modifying the second blood pressure value using the correction value to correlate the first and second blood pressure values;

transferring at least the first blood pressure value and the second blood pressure value to a web portal from the home blood pressure device; and

generating a blood pressure trend plot including at least the first blood pressure value the second blood pressure value.
