Summary

High-throughput oxygen therapy is known as an alternative to non-invasive ventilation, with a benefit in terms of survival in non-hypercapnic respiratory failure patients.

The use of high-throughput oxygen therapy is well studied in stable chronic obstructive pulmonary disease (COPD) patients and has as known effects the decrease of transcutaneous CO2 and respiratory rate, and the increase in the inspiratory/expiratory time report, in the tidal volume and in the forced expiratory volume per second.

In the event of an exacerbation, high-flow oxygen therapy has shown to be beneficial in terms of increased mean airway pressure, tidal volume with a decrease in hypercapnia, and respiratory rate.

The net effect on the CO2 pressure is linked to the CO2 clearance of the dead anatomical space by the high throughput. The effect can be compared with the one of non invasive ventilation in a stable COPD patient.

Oxygen therapy, even in patients with non-hypoxic COPD at rest, has benefits in terms of performance and improvement of quality of life. High-throughput oxygen therapy has also shown a benefit in COPD patients in revalidation units, in terms of exercise performance and oxygenation.

However, the reconditioning of critical patients in acute situations, by means of nasal goggles, has never been studied.

Conditions

  • Hypoxemic Respiratory Failure

Interventions

DEVICE

Cyclometer Ergometer

The measurements are carried out on a max effort of 12 minutes on a cyclometer ergometer with a constant load (Motomed viva2 light). A first effort is made with a Venturi type mask whose Inspired Fraction in Oxygen (FiO2) is set for a pulsated oxygen saturation (SpO2) greater than or equal to 85%, and then a second at 2h interval with high-throughput googles (Optiflow) with the corresponding FiO2.
