PC-based physiologic monitor and system for resolving apnea episodes during sedation
First Claim
1. A personal computer based physiologic monitor system comprising:
- a personal computer having a display and an input/output port for attachment to an external device;
a physiologic sensor coupled to the personal computer through the input/output port, wherein a modified output of the physiologic sensor is graphically displayed on the display; and
a controller for the physiologic sensor, wherein the controller is adapted to modify the output of the physiologic sensor, and wherein at least a portion of the controller is disposed in the personal computer and provides a feedback control signal for modifying the output of the physiologic sensor.

Abstract
An anesthesia delivery and monitoring system for use during outpatient surgery performed under sedation level anesthesia that includes a ventilatory system, a system for supplying sedation anesthesia, a respiratory sensor adapted to detect a respiration parameter of such a patient, and a system for supplying a timed back-up breath to such a patient through the ventilatory system. The timed back-up breaths are supplied in response to the respiration parameter falling outside a preset threshold and at a positive pressure exceeding a base operating pressure of the respiratory system. The system for supplying sedation anesthesia is an intravenous supply system for anesthesia, a ventilatory system coupled to the patient, a needle and syringe, or any combination thereof. The respiratory system includes a PC-based physiologic monitor with user modified feedback control signal.

12. A ventilatory system for use during outpatient surgery performed under sedation level anesthesia comprising:
-
a pressure/flow generating system adapted to be coupled to a patient;
means for supplying sedation anesthesia to such a patient;
a sensor coupled to such a patient and adapted to detect a respiration parameter of such a patient; and
a controller that receives an output from the sensor and controls the pressure/flow generating system so as to provide a timed back-up breath to such a patient based on the output from the sensor, wherein the timed back-up breath is supplied in response to the respiration parameter falling outside a preset threshold, and wherein the timed back-up breath is supplied at a positive pressure exceeding a base operating pressure of the pressure/flow generating system. - View Dependent Claims (13)

14. A method of monitoring a subject'"'"'s physiologic parameters on a personal computer comprising the steps of:
-
attaching a physiologic sensor to the personal computer through an input/output port thereof;
graphically displaying a modified output of the physiologic sensor on the display of the personal computer; and
modifying the output of the physiologic sensor by providing a feedback control signal from the personal computer that controls the modification of the output of the physiologic sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A ventilatory method for a patient comprising the steps of:
-
supplying a flow of gas to an airway of a patient;
coupling a respiratory sensor to such a patient to detect a respiration parameter of such a patient; and
supplying a timed back-up breath to such a patient through the system used for supplying the flow of gas, wherein the timed back-up breath is supplied in response to the detected respiration parameters falling outside a preset threshold, and wherein the timed back-up breath is supplied at a positive pressure exceeding a base operating pressure of the system used for supplying the flow of gas gases. - View Dependent Claims (23, 24)
