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.
Claims21
A method for managing the 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 the oxygen saturation level of the blood in the patient as a function of the PEEP level versus time;
- and
- displaying a graph of the function versus time.
A method for managing the 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 based on readings from the oximeter;
- monitoring a PEEP of the patient;
- graphing the oxygen saturation level of the blood in the patient versus time;
- graphing the PEEP level of the patient versus time;
- and
- displaying both the oxygen saturation level of the blood in the patient versus time and the PEEP level of the patient versus time on one graph.
A method for managing the 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 based on readings from the oximeter;
- monitoring the PEEP of the patient;
- monitoring the fractional inspired oxygen level of the patient;
- graphing the oxygen saturation level of the blood in the patient versus time;
- graphing the PEEP level of the patient versus time;
- graphing the fractional inspired oxygen level of the patient versus time;
- and
- displaying the oxygen saturation level of the blood in the patient versus time, the fractional inspired oxygen level of the patient versus time, and the PEEP level of the patient versus time on one graph.
A computer-readable medium having computer-executable instructions for performing a method for managing the 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 the oxygen saturation level of the blood in the patient in a mathematical relationship to the PEEP level versus time;
- and
- repeatedly displaying a graph of the mathematical relationship versus time.
A medical ventilator system, comprising:
- means for repeatedly monitoring a patient during ventilation with an oximeter;
- means for repeatedly monitoring an oxygen saturation level of blood in the patient during ventilation;
- means for repeatedly monitoring a PEEP level of the patient;
- means for repeatedly graphing the oxygen saturation level of the blood in the patient in a as a mathematical relationship to the PEEP level versus time;
- and
- means for repeatedly displaying a graph of the mathematical relationship versus time.
