Abstract
Methods of treating subjects may include assisting breathing of the subject via an external respiratory support device. The methods of treating subjects may further include delivering an electrical signal to a first nerve of the subject, wherein delivering of the first signal blocks a pain signal from a pulmonary stretch pain receptor. The methods may further include placing one or more electrodes proximate a first nerve, wherein the first electrodes are supported on an intravenous catheter.
Claims6
A method for treating a subject, the method comprising:
- assisting breathing of the subject via positive pressure ventilation from an external respiratory support device;
- delivering a first pulsed electrical signal to a first nerve of the subject, during an inspiration phase of a breath assisted by the external respirator support device, wherein delivery of the first pulsed electrical signal reduces aberrant neuro signaling caused by the external respiratory support device;
- delivering a second pulsed electrical signal to a second nerve of the subject, wherein delivery of the second pulsed electrical signal creates negative pressure in a thoracic cavity of the subject;
- after the inspiration phase, discontinuing the first pulsed electrical signal;
- after the inspiration phase, measuring, via one or more sensors, a blood-protein level;
- based on the measuring step, adjusting the second pulsed electrical signal to generate an adjusted second electrical signal, wherein adjusting the second pulsed electrical signal comprises:
- adjusting a frequency;
- adjusting an amplitude;
- adjusting a pulse width;
- adjusting a duration of the electrical signal;
- or
- a combination thereof;
- delivering the adjusted second electrical signal to the second nerve;
- and
- while delivering the adjusted second electrical signal, delivering the first pulsed electrical signal to the first nerve.
