Systems, methods and apparatus for respiratory support of a patient

A method for supplementing the respiration of a spontaneously breathing patient comprising the steps of:

• inserting an oxygen-bearing gas delivery device into the respiratory system of the patient,
• detecting spontaneous respiration of the patient with respiration sensors,
• identifying an inhalation phase and an exhalation phase using information from the respiration sensors,
• synchronizing delivery of a volume of oxygen-bearing gas based on the patient's need as determined by a measurement of the patient's respiration to the patient during an inhalation phase to augment inspiration or during an exhalation phase to augment exhalation, and wherein the delivered volume of the oxygen-bearing gas is increased, decreased, switched-on or switched-off based on feedback from the respiration sensors.

A device for supplementing the respiration of a spontaneously breathing patient comprising

• sensors for monitoring the spontaneous respiration of the patient
• a catheter configured to be inserted into the respiratory system of the patient,
• a control unit communicating with the sensors configured to identify an inhalation and an exhalation phase of the patient's spontaneous respiration and the need for supplemental gas volume based on the patient's need as determined by a measurement of the patient's respiration wherein the control unit is further configured to administer a supplemental amount of oxygen-bearing gas through the catheter synchronously with either an inhalation phase or an exhalation phase, and
• wherein the supplemental volume of the oxygen-bearing gas is increased, decreased, switched-on or switched-off based on feedback from the sensors.

A system for supplementing the respiration of a spontaneously breathing patient, comprising:

• a transtracheal catheter adapted for placement in an airway of a patient and comprising at least one respiration sensor, wherein the transtracheal catheter is configured to not obstruct an airway of the patient;
• and
• a wearable mobile respiratory device comprising:
• a control unit in communication with the respiration sensor, the control unit configured to determine the need for additional volume based on the patient's need as determined by a measurement of the patient's respiration and to control the delivery of a volume of supplemental gas to the patient in synchrony with a portion of the patient's spontaneous breathing pattern when the need for breath augmentation is determined.
