Abstract

The present disclosure relates to a system and method for sampling parametric data provided with a patient monitoring device. A disclosed method includes sampling parametric data associated with a patient and adjusting a sampling interval during the sampling of the parametric data based on a change in a frequency of a periodic physiological event associated with the patient. A disclosed system includes a server computer operative to sample parametric data associated with a patient and to adjust a sampling interval during the sampling of the parametric data based on a change in a frequency of a periodic physiological event associated with the patient.

Claims

1. A method of sampling parametric data by a data collection system, the parametric data being provided with a ventilator system and being associated with a patient monitored by the ventilator system, the method including:

receiving information associated with a first respiration rate of a monitored patient, the information associated with the first respiration rate being provided with the ventilator system;

setting a data sampling rate to substantially match the first respiration rate;

sampling parametric data associated with the monitored patient at the data sampling rate, the parametric data being provided with the ventilator system;

receiving information associated with a second respiration rate of the monitored patient, the second respiration rate being different from the first respiration rate;

adjusting, during the sampling of the parametric data, the data sampling rate to substantially match the second respiration rate; and

sampling parametric data associated with the monitored patient at the adjusted data sampling rate.

2. The method of claim 1, further including sending a request for the parametric data associated with the patient to the ventilator system.

3. The method of claim 2, further including receiving the requested parametric data and a respiration rate from the ventilator system upon sending the request.

4. The method of claim 1, further including storing the received parametric data in a server database of the data collection system.

5. The method of claim 1, further including receiving a notification from the ventilator system following each of a plurality of successive respiration cycles of the monitored patient, the notification indicating that parametric data associated with the previous respiration cycle of the patient is available at the ventilator system.

6. The method of claim 5, further including:

sending a request to the ventilator system for the available parametric data associated with the previous respiration cycle of the patient following the receipt of each notification; and

receiving the requested parametric data at the data collection system following the sending of each request.

7. The method of claim 1, further including limiting the adjusted data sampling rate to a predetermined maximum rate upon the second respiration rate exceeding the predetermined maximum rate.

8. The method of claim 1, wherein the first and second respiration rates are received following a request from the data collection system to the ventilator system for parametric data.

9. The method of claim 1, further including determining the first respiration rate based on the received information associated with the first respiration rate, and determining the second respiration rate based on the received information associated with the second respiration rate.

10. A method of sampling data provided with a patient monitoring device, the method including:

sampling parametric data associated with a patient and provided with a patient monitoring device;

determining a frequency of a periodic physiological event associated with the patient; and

adjusting a sampling rate during the sampling of the parametric data based on a change in the frequency of the periodic physiological event associated with the patient.

11. The method of claim 10, further including receiving information associated with the frequency of the periodic physiological event from the patient monitoring device.

12. The method of claim 11, further including setting the sampling rate to match the frequency of the periodic physiological event associated with the patient.

13. The method of claim 12, further including limiting the sampling rate to a predetermined maximum rate upon the frequency of the periodic physiological event exceeding the predetermined maximum rate.

14. The method of claim 10, further including receiving a notification of each of a plurality of successive occurrences of the periodic physiological event associated with the patient.

15. The method of claim 14, wherein the sampling rate is adjusted to sample the parametric data associated with the patient following the receipt of each notification.

16. The method of claim 10, wherein the periodic physiological event associated with the patient includes at least one of respiration and pulse.

17. The method of claim 10, further including sampling parametric data associated with the monitored patient at the adjusted sampling rate, and storing the sampled parametric data in a server database.

18. A data collection system including:

a database; and

at least one server computer operative to sample parametric data associated with a patient and to store the sampled parametric data in the database, the parametric data being provided with a patient monitoring device, the at least one server computer adjusting a sampling frequency during a sampling of the parametric data based on a change in a determined frequency of a periodic physiological event associated with the patient.

19. The data collection system of claim 18, wherein the at least one server computer is operative to sample parametric data provided with each of a plurality of patient monitoring devices at a different sampling frequency.

20. The data collection system of claim 18, wherein the at least one server computer receives information associated with the frequency of the periodic physiological event from the patient monitoring device.

21. The data collection system of claim 20, wherein the at least one server computer is further operative to set the sampling frequency to match the frequency of the periodic physiological event associated with the patient.

22. The data collection system of claim 18, wherein the at least one server computer is further operative to receive a notification of each of a plurality of successive occurrences of the periodic physiological event associated with the patient from the patient monitoring device.

23. The data collection system of claim 22, wherein the at least one server computer is further operative to sample the parametric data associated with the patient following the receipt of each notification.

24. The data collection system of claim 18, wherein the periodic physiological event associated with the patient includes at least one of respiration and pulse.
