Abstract

A bar graph display feature for clinical viewing of supplemental oxygen (SpO₂) or blood oxygen percentage, Pulse Rate, and Fraction of Inspired Oxygen (FiO₂) levels as derived from an adaptive supplemental oxygen controller is described. A bar graph is a moving histogram of SpO₂, Pulse Rate, and FiO₂ by using a computer that calculates a FiO₂ by using SpO₂ feedback. The bar graph displays stored data on a flat screen or LCD over specified periods. Other display features include alarm conditions: 1) Upper FiO₂ Limit, 2) Motion Detection, 3) Power Loss, 4) Battery Backup, and 5) Pressure Loss. The Upper FiO₂ Limit is a calculation of FiO₂ by using SpO₂ feedback from a pulse oximeter. The invention also relates to an adaptive oxygen control system whereas adjustment of system time constant and system delay provides application of the control system for use with an oxygen mask, oxyhood or nasal cannula.

Claims

1. A computer calculated display perimeters by means of a moving histogram over a predetermined time period.

2. The computer calculated display perimeters according to claim 1, wherein the computer calculated display perimeters are FiO₂, SpO₂ and patient pulse rate.

3. The computer calculated display perimeters according to claim 1, wherein the predetermined time period is selected from group consisting of five minutes, one hour, eight hours or twenty-four hours.

4. The computer calculated display perimeters according to claim 1, wherein the computer calculated display perimeters further comprise alarm and alert conditions detected from a computerized adaptive controller receiving SpO₂ and FiO₂ data.

5. The computer calculated display perimeters according to claim 4, wherein the alarm and alert conditions detected from a computerized adaptive controller receiving SpO₂ and FiO₂ data comprise Upper FiO₂ Limit, Motion Detection, Power Loss, Battery Backup, and Pressure Loss.

6. A USB data port access for linking a computerized storage device for the long-term storage of computer calculated display perimeters.

9. The computerized storage device according to claim 6, wherein the computerize storage device comprises an external hard drive, a main frame centralized computer or an information management system.

19. The computerized storage device according to claim 6, wherein the long-term memory storage device data can be reviewed for therapeutic and diagnostic analysis of the patient.

20. The data review according claim 19, wherein the data is reviewed either by direct display on the supplemental oxygen delivery system flat screen or LCD, or by a hospital data archiving system.

7. The USB data port access for linking a computerized storage device wherein the computerized storage device comprises a removable memory device.

8. The computerized storage device according to claim 7, wherein the removable memory device comprises a flash drive, a memory card or a memory stick.

10-18. -18. (canceled)

21. A means to adjust system time constant and delay of an adaptive oxygen control system using SpO₂ feedback for use with a nasal cannula, an oxygen mask or oxyhood.
