System and method for treating patients requiring mechanical ventilation

A method comprising:

• selecting at least two sites on a body of a patient requiring mechanical ventilation for delivery of a light signal to at least one primary inspiratory muscle of the patient by a photoceutical medical device,
• wherein the photoceutical medical device comprises:
• at least one super pulsed laser to provide superpulsed light of a first wavelength,
• at least two non-coherent light sources to provide light of a second wavelength, and
• at least two other non-coherent light sources to provide light of a third wavelength,
• such that the light signal comprises superpulsed light of the first wavelength, light of the second wavelength, and light of the third wavelength;
• and
• delivering the light signal to the at least one primary inspiratory muscle of the patient by the photoceutical medical device at one of the at least two sites for a first time period from a first start time to a first end time;
• and
• after the first end time, delivering the light signal to the at least one primary inspiratory muscle of the patient by the photoceutical medical device at another of the at least two sites for a second time period from a second start time to a second end time;
• and
• wherein the light signal is applied to preserve a respiratory function within the body of the patient requiring mechanical ventilation while on mechanical ventilation.
