Abstract

A computer-implemented patient information provisioning method is disclosed. The method includes automatically extracting with a computer system, from records maintained for a patient under care in a healthcare facility, information from a electronic medical record; obtaining with the computer system information about a medical ventilator treating the patient; using the information from the electronic medical record and the information about the medical ventilator to determine whether a potentially dangerous condition exists with respect to the ventilator; and electronically alerting a caregiver if it is determined that a potentially dangerous condition exists.

Claims

1. A computer-implemented patient information provisioning method, comprising:

automatically extracting with a computer system, from records maintained for a patient under care in a healthcare facility, information from a electronic medical record;

obtaining with the computer system information about a medical ventilator treating the patient;

using the information from the electronic medical record and the information about the medical ventilator to determine whether a potentially dangerous condition exists with respect to the ventilator; and

electronically alerting a caregiver if it is determined that a potentially dangerous condition exists.

2. The method of claim 1, wherein the information from the electronic medical record comprises data from an arterial blood gas analysis.

3. The method of claim 1, further comprising obtaining with the computer system textual information from a medical report for the patient and using the textual information to determine whether a potentially dangerous condition exists with respect to the ventilator.

4. The method of claim 1, wherein the information about the medical ventilator comprises information about a measured peak pressure or set tidal volume for the ventilator.

5. The method of claim 4, wherein a potential dangerous condition is determined to exist if the information from the electronic medical record indicates an arterial blood gas level of PaO₂/FIO₂<

approximately 300, and the measured peak pressure is above about 35 mm H₂0 or the measured set tidal volume is above about 8 mL/kg PBW.

6. The method of claim 1, wherein electronically alerting a caregiver comprises providing an electronic messaging service with a description of an alerting condition of the patient, and information identifying the patient.

7. The method of claim 1, further comprising blocking alerting of the caregiver if the caregiver has previously been notified about the patient a predetermined number of times in a predetermined time period.

8. A computing system, comprising:

a medical ventilator for providing mechanical ventilation to a patient;

one or more processors;

memory; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including;

instructions for automatically extracting, from records maintained for the patient, information from an electronic medical record;

instructions for obtaining with the computer system information about the medical ventilator;

instructions for using the information from the electronic medical record and the information about the medical ventilator to determine whether a potentially dangerous condition exists with respect to the ventilator; and

instructions for electronically alerting a caregiver if it is determined that a potentially dangerous condition exists.

9. The system of claim 8, wherein the information from the electronic medical record comprises data from an arterial blood gas analysis.

10. The system of claim 8, further comprising instructions for obtaining textual information from a medical report for the patient and using the textual information to determine whether a potentially dangerous condition exists with respect to the ventilator.

11. The system of claim 8, wherein the information about the medical ventilator comprises information about a measured peak pressure or set tidal volume for the ventilator.

12. The system of claim 11, wherein a potential dangerous condition is determined to exist if the information from the electronic medical record indicates an arterial blood gas level of PaO₂/FIO₂<

approximately 300, and the measured peak pressure is above about 35 mm H₂0 or the measured set tidal volume is above about 8 mL/kg PBW.

13. The system of claim 8, wherein electronically alerting a caregiver comprises providing an electronic messaging service with a description of an alerting condition of the patient, and information identifying the patient.

14. The system of claim 8, further comprising instructions for blocking alerting of the caregiver if the caregiver has previously been notified about the patient a predetermined number of times in a predetermined time period.

15. A computer-implemented patient information provisioning system, comprising:

one or more mechanical ventilators for treating patients in a healthcare facility;

an interface operating on a computer processor system programmed to obtain data about operating parameters of the one or more ventilators and data from a central electronic medical records system operated by the healthcare facility; and

an electronic patient evaluator to use the data about the operating parameters of the one or more ventilators and the data from the central electronic medical records system to identify the presence of a potentially dangerous condition exists with respect to one or more ventilators; and

an alert module to provide, for transmission to one or more caregivers, a notification of the identified dangerous condition.

16. A computer-implemented patient information provisioning system, comprising:

one or more mechanical ventilators for treating patients in a healthcare facility;

an interface operating on a computer processor system programmed to obtain data about operating parameters of the one or more ventilators and data from a central electronic medical records system operated by the healthcare facility; and

means for identifying presence of a potentially dangerous condition from the data about operating parameters and the data from a central electronic medical records system; and

an alert module to provide, for transmission to one or more caregivers, a notification of the identified dangerous condition.
