Medical ventilator with integrated oximeter data
First Claim
Patent Images
1. A method for managing ventilation of a patient being ventilated by a medical ventilator, the method comprising:
- monitoring a patient during ventilation with an oximeter;
monitoring an oxygen saturation level of blood in the patient during ventilation;
monitoring a PEEP level of the patient;
graphing a function of the oxygen saturation level of the blood of and the PEEP level versus time;
displaying a graph of the function versus time;
issuing a first alarm if the function is outside of a preset threshold, a drop in the oxygen saturation level of the blood is detected, and the PEEP level does not change; and
issuing a second alarm if the function is outside of the preset threshold and the drop in the oxygen saturation level of the blood occurred after the PEEP level dropped.

Abstract
This disclosure describes systems and methods for managing the ventilation of a patient being ventilated by a medical ventilator. The disclosure describes a novel approach of displaying ventilator information integrated with oximeter information. The disclosure further describes a novel approach of alarming based on the integration of ventilator information with oximeter information.

14. A non-transitory computer-readable medium having computer-executable instructions for performing a method for managing ventilation of a patient being ventilated by a medical ventilator, the method comprising:
-
repeatedly monitoring a patient during ventilation with an oximeter; repeatedly monitoring an oxygen saturation level of blood in the patient during ventilation; repeatedly monitoring a PEEP level of the patient; repeatedly graphing a mathematical relationship of the oxygen saturation level of the blood and the PEEP level versus time; repeatedly displaying a graph of the mathematical relationship versus time; repeatedly issuing a first alarm if the mathematical relationship is outside of a preset threshold, a drop in the oxygen saturation level of the blood is detected, and the PEEP level does not change; and repeatedly issuing a second alarm if the mathematical relationship is outside of the preset threshold and the drop in the oxygen saturation level of the blood occurred after a drop in the PEEP level. - View Dependent Claims (15)

16. A medical ventilator system, comprising:
-
means for monitoring a patient during ventilation with an oximeter; means for monitoring an oxygen saturation level of blood in the patient during ventilation; means for monitoring a PEEP level of the patient; means for graphing a mathematical relationship of the oxygen saturation level of the blood and the PEEP level versus time; means for displaying a graph of the mathematical relationship versus time; means for determining that the mathematical relationship is outside a preset threshold; means for determining that the PEEP level of the patient dropped prior to a drop in the oxygen saturation level of the blood in the patient, determining that the oxygen saturation level of the blood in the patient dropped prior to a drop in the PEEP level, and determining the drop in the oxygen saturation level of the blood when the PEEP level does not change; means for issuing a first alarm if the mathematical relationship is outside of the preset threshold, the drop in the oxygen saturation level of the blood is detected, and the PEEP level does not change; and means for issuing a second alarm if the mathematical relationship is outside of the preset threshold and the drop in the oxygen saturation level of the blood occurred after the PEEP level dropped. - View Dependent Claims (17)
