Abstract
Various methods and systems are provided for performing nasal high flow therapy. In one example, a method for respiratory support includes: delivering an air and oxygen mixture for nasal high flow therapy to a patient at a flow setting, the flow setting determined based on a peak inspiratory flow obtained during a previous, spontaneous breathing mode during mechanical ventilation of the patient. The flow setting may be a flow rate of a heated and humidified mixture of air and oxygen delivered via a high flow nasal cannula.
Claims20
A method for respiratory support, comprising:
- delivering an air and oxygen mixture for nasal high flow therapy to a patient at a flow setting, the flow setting determined via a controller coupled to a ventilator, based on a peak inspiratory flow obtained during a previous, spontaneous breathing mode during invasive mechanical ventilation of the patient with the ventilator, wherein the invasive mechanical ventilation is a different mechanical ventilation than the nasal high flow therapy;
- and
- wherein the air and oxygen mixture of the nasal high flow therapy and the air and oxygen mixture of the ventilator are from a same source.
A method for respiratory support, comprising:
- while operating a respiratory support device, attached to a patient, in a spontaneous breathing mode during invasive mechanical ventilation of the patient, displaying a breathing waveform of the patient, and, in response to successful completion of a spontaneous breathing trial, obtaining a peak inspiratory flow from the breathing waveform;
- and
- following the spontaneous breathing mode and after stopping the invasive mechanical ventilation of the patient, delivering an air and oxygen mixture via a nasal high flow therapy system to the patient at a flow rate, wherein the flow rate at start-up of nasal high flow therapy is determined based on the peak inspiratory flow,
- wherein the invasive mechanical ventilation is a different mechanical ventilation than the nasal high flow therapy.
A system, comprising:
- a nasal high flow therapy system;
- an invasive mechanical ventilator adapted to provide respiratory support to a patient, wherein the invasive mechanical ventilator is a different respiratory support than the nasal high flow therapy;
- and
- a control system with one or more controllers with computer readable instructions stored on non-transitory memory that, when executed during operation of the invasive mechanical ventilator, cause the one or more controllers to:
- execute a spontaneous breathing mode in response to a request for the spontaneous breathing mode;
- during execution of the spontaneous breathing mode during the invasive mechanical ventilation, acquire flow data from a plurality of breath cycles;
- and
- determine a nasal high flow therapy flow setting based on a peak inspiratory flow of the acquired flow data.
