Respiratory support and/or controlled mechanical ventilation of a patient are provided. A ventilation apparatus may include a ventilator, a transtracheal prosthesis, and a respiratory relief device. The transtracheal prostheses and ventilation catheter may be arranged such that the patient can breathe freely through the upper airway and/or the tracheal prostheses. Respiratory sensors may measure a breathing rate, lung pressure, airway pressure, or a combination thereof. Pulses of gas may be provided to the patient through the ventilation catheter during inspiration. The pulses may have a first volume while the patient breathes normal and a second volume when the sensors detect a cessation of breathing or reduction in breathing volume. The second volume may be provided at 1-5 times the normal breathing rate, with a volume 25-500% times the first volume, or both.
1. A ventilation apparatus comprising (a) a ventilator adapted to (i) provide a pulse of gas to the patient during inspiration by a patient, wherein the pulse has a first volume; and(ii) provide pulses of gas to a patient after detection of a cessation of breathing or reduction in breathing volume o
1. A ventilation apparatus comprising (a) a ventilator adapted to (i) provide a pulse of gas to the patient during inspiration by a patient, wherein the pulse has a first volume; and(ii) provide pulses of gas to a patient after detection of a cessation of breathing or reduction in breathing volume of the patient, wherein the pulses each have a second volume and wherein (1) the pulses are provided at a rate that is 1-5 times the normal breathing rate, (2) the second volume is 25-500% greater than the first volume, or (3) the pulses are provided at a rate that is 1-5 times the normal breathing rate and the second volume is 25-500% greater than the first volume;(b) a gas delivery circuit operably connected to the ventilator;(c) one or more respiratory sensor adapted to determine when the patient inspires, to calculate a normal breathing volume for the patient, to detect a cessation of breathing or reduction in breathing volume of the patient; and(d) a respiratory relief device, wherein the respiratory relief device is configured to allow the patient to exhale to atmosphere;(e) a pressure transducer to measure the pressure in the lungs, to detect overpressure in the lungs, or both; andwherein the respiratory relief device comprises an active valve. 2. The ventilation apparatus of claim 1, wherein the respiratory relief device comprises a seat and a diaphragm; wherein the valve receives a pilot pressure signal from the lungs or from the ventilator, and wherein the pilot pressure signal regulates the position of the diaphragm against the seat. 3. The ventilation apparatus of claim 1, wherein the respiratory relief device has an open state and a closed state. 4. The ventilation apparatus of claim 3, wherein the respiratory relief device is adapted to be provided in a closed state while the one or more respiratory sensor detects that the patient is breathing within the normal breathing rate, normal lung pressure, normal airway pressure, or a combination thereof. 5. The ventilation apparatus of claim 3, wherein the one or more respiratory sensor is adapted to detect a variation in the patient's breathing rate from the normal lung pressure, a variation in the patient's lung pressure from the normal lung pressure, a variation in the patient's airway pressure from the normal airway pressure, or a combination thereof. 6. The ventilation apparatus of claim 5, wherein the respiratory relief device is adapted to open or be opened in response to detection of the variation. 7. The ventilation apparatus of claim 1, further comprising: a ventilation catheter operably connected to the gas delivery circuit;wherein the pulses of gas are provided to the patient through the ventilation catheter. 8. The ventilation apparatus of claim 7, further comprising: a patient ventilation interface, wherein the ventilation catheter is placed coaxially in the patient ventilation interface; and wherein the patient ventilation interface and the ventilation catheter are arranged such that a patient using the ventilation apparatus can breathe freely through the patient's upper airway. 9. The ventilation apparatus of claim 1, wherein the respiratory relief device comprises an active valve. 10. The ventilation apparatus of claim 1, wherein the respiratory relief device comprises a seat and a diaphragm; wherein the respiratory relief device receives a pilot pressure signal from the lungs or from the ventilator, and wherein the pilot pressure signal regulates the position of the diaphragm against the seat. 11. A method of providing ventilation to a patient comprising (a) using one or more respiratory sensor to determine when the patient inspires;(b) providing a pulse of gas to the patient during inspiration by the patient, wherein the pulse has a first volume;(c) using the one or more respiratory sensor to calculate a normal breathing volume for the patient;(d) providing a respiratory relief device, wherein the respiratory relief device is configured to allow the patient to exhale to atmosphere;(e) detecting a cessation of breathing or reduction in breathing volume of the patient;(f) after detecting a cessation of breathing or reduction in breathing volume of the patient, providing pulses of gas to the patient, wherein the pulses each have a second volume and wherein (i) the pulses are provided at a rate that is 1-5 times the normal breathing rate, (ii) the second volume is 25-500% greater than the first volume, or (iii) the pulses are provided at a rate that is 1-5 times the normal breathing rate and the second volume is 25-500% greater than the first volume;(g) using a pressure transducer to measure the pressure in the lungs, to detect overpressure in the lungs, or both; and(h) opening the respiratory relief device when overpressure in the lungs is detected. 12. The method of claim 11, further comprising: using the one or more respiratory sensor to measure the patient's breathing rate;using the one or more respiratory sensor to calculate a normal breathing rate for the patient;providing the respiratory relief device in a closed state while the one or more respiratory sensor detects that the patient is breathing within the normal breathing rate;using the one or more respiratory sensor to detect a variation in the patient's breathing rate from the normal breathing rate; andopening the respiratory relief device in response to detection of the variation in the patient's breathing rate from the normal breathing rate.
