Automated inspiratory muscle training for patients receiving mechanical ventilation
A system and method for automated inspiratory muscle strength exercise includes software for setting a mechanical ventilator for a pressure regulated breath with an initial pressure target that is at the highest pressure setting a patient can tolerate and increasing the pressure target as tolerated.
1. One or more computer-readable media having computer-useable instructions embodied thereon for performing a method of inspiratory muscle strength training, the method comprising:
providing a sensing assembly and gas delivery device having an inhalation assembly that provides inspiratory air flow to a patient;
imposing delivery of inspiratory air flow using an inspiratory training stimulus; and
controlling the inhalation assembly to deliver inspiratory air flow using the inspiratory training stimulus during an entire inhalation act for every breath by the patient.
2. The media of claim 1 , wherein the gas delivery device is a mechanical ventilator.
3. The media of claim 1 , wherein the inspiratory training stimulus is a pressure between 1 to 80 cm of H 2 O.
4. The media of claim 3 , wherein the inspiratory training pressure is between 2-20 cm of H 2 O.
5. One or more computer-readable media having computer-useable instructions embodied thereon for performing a method of inspiratory muscle strength training, the method comprising:
receiving respiratory parameters of a patient from a sensing assembly;
calculating an inspiratory training stimulus variable from the respiratory parameters; and
providing said inspiratory training stimulus variable to a gas delivery device, wherein said gas delivery device delivers inspiratory air flow to the patient and comprises settings for adjusting the inspiratory airflow; and
adjusting the gas delivery settings to administer air flow to the patient to impose negative pressure on the patient during inhalation at the inspiratory training stimulus variable.
6. The media of claim 5 , wherein the gas delivery device is a mechanical ventilator.
7. The media of claim 5 , wherein the inspiratory training stimulus is a pressure between 1 to 80 cm of H 2 O.
8. The media of claim 7 , wherein the inspiratory training pressure is between 2-20 cm of H 2 O.
9. The media of claim 5 , wherein the inspiratory training stimulus is a target power of breathing.
10. The media of claim 5 , wherein the method further comprises:
receiving a second set of respiratory parameters of the patient comprising a response of the patient to the inspiratory training stimulus;
calculating a second inspiratory training stimulus variable from the second set of respiratory parameters;
providing said second inspiratory training stimulus variable to the gas delivery device;
adjusting the gas delivery settings to administer air flow to the patient to impose negative pressure on the patient during inhalation at the second inspiratory training stimulus variable; and
repeating the steps herein as necessary.
