Apparatus to deliver oxygen to a patient
First Claim
1. A medical-effector-system procedure room unit comprising a procedure-room-unit host controller which contains an oxygen delivery program which performs the steps of:
- controlling the delivery of oxygen at a variable first rate to at least one respiratory-gas-delivery oral prong of a cannula assembly operatively connected to a patient, when the patient is determined to be inhaling and exhaling through the mouth;
controlling the delivery of oxygen at a variable second rate to at least one respiratory-gas-delivery nasal prong of the cannula assembly when the patient is determined to be breathing through the nose and when the patient is determined to be inhaling; and
controlling the delivery of oxygen at a variable third rate to the at-least-one respiratory-gas-delivery nasal prong when the patient is determined to be breathing through the nose and when the patient is determined to be exhaling, wherein the patient has a variable percentage of blood oxygen saturation and wherein the first, second and third rates depend on the percentage of blood oxygen saturation.

Abstract
Disclosed is an oxygen delivery device for regulating the flow of oxygen from an oxygen source to a respiratory cannula located on the face of a patient. A host controller coupled to the oxygen delivery device accepts an input from a medical monitor relating to the blood oxygen saturation percentage of the patient. The host controller then regulates the rate of oxygen supplied to the patient based in part upon the blood oxygen saturation percentage of the patient. A high rate of oxygen is supplied to the patient when the controller detects a blood oxygen saturation level below a predetermined percentage and a low rate of oxygen is supplied when the controller detects a blood oxygen saturation level above a predetermined percentage in an order to minimize wasted oxygen.

9. A medical-effector-system procedure room unit comprising a procedure-room-unit host controller which contains an oxygen delivery program which performs the steps of:
- controlling the delivery of oxygen at a variable nasal-inhale oxygen-delivery flow rate to at least one respiratory-gas-delivery nasal prong of a cannula assembly operatively connected to a patient, when the patient is determined to be breathing through the nose and when the patient is determined to be inhaling; and
controlling the delivery of oxygen at a nasal-exhale oxygen-delivery flow rate to the at-least-one respiratory-gas-delivery nasal prong when the patient is determined to be breathing through the nose and when the patient is determined to be exhaling, wherein the patient has a variable percentage of blood oxygen saturation and wherein the nasal-inhale oxygen-delivery flow rate is a variable rate which depends on the percentage of blood oxygen saturation. - View Dependent Claims (10)
