Clinical Trial Summary

Background The exacerbation of respiratory failure that occurs after endotracheal intubation often occurs in patients who have received mechanical ventilation therapy, and when it occurs, it emerges as an important issue to consider reintubation of endotracheal intubation. High-flow nasal cannula (HFNC) through nasal cannula is known to produce positive airway pressure and deliver a certain amount of oxygen, and recently reported clinical studies have demonstrated the effect of lowering the risk of reintubation after endotracheal intubation, which is recommended for use in recent clinical practice guidelines. However, in patients at high risk of intubation failure, the combination of high-flow oxygen therapy and non-invasive positive-pressure ventilation therapy rather than the application of high-flow oxygen therapy alone through nasal cannula is helpful in reducing the rate of reintubation of endotracheal intubation. However, an alternative to non-invasive positive-pressure ventilation therapy is needed as there is a possibility of complications such as aspiration pneumonia, maladaptation of the application device (mask), and discomfort, making it difficult to apply it in the field.

Recently, it has been reported that high flow oxygen therapy through an asymmetric nasal cannula forms sufficient positive pressure in terms of respiratory dynamics, which makes the patient feel comfortable and reduces work of breath. However, no clinical studies have yet compared physiological effects using this method in patients at high risk of extubation failure.

Goal The investigators would like to compare the physiological effects of high flow oxygen therapy through 'asymmetric nasal cannula' with high flow oxygen therapy through 'standard nasal cannula' in patients identified as high-risk groups for valvular failure.

Hypothesis 'Asymmetric nasal cannula' reduces work of breath compared to 'standard nasal cannula' in high-risk patients with valvular failure.

Intervention

Device:
• Asymmetric High flow nasal cannula
Both the test group and the control group apply high flow oxygen therapy for at least 24 hours from the time of initial excretion (0h), and only the nasal interface is applied differently depending on the allocation group. The initial flow rate setting is 10 L/min, and it can be adjusted up to 50 L/min within the range where the subject does not experience discomfort. Except for cases where the patient complains of being hot, the initial temperature setting is 37°C, and the inhaled oxygen concentration (FiO2) may be adjusted to a target of 93% or more of peripheral oxygen saturation (SpO2) in the range of 21 to 100%. After 24 hours, high flow oxygen therapy is discontinued and conventional oxygen therapy can be applied if necessary.
• Standard(symmetric) High flow nasal cannula
Both the test group and the control group apply high flow oxygen therapy for at least 24 hours from the time of initial excretion (0h), and only the nasal interface is applied differently depending on the allocation group. The initial flow rate setting is 10 L/min, and it can be adjusted up to 50 L/min within the range where the subject does not experience discomfort. Except for cases where the patient complains of being hot, the initial temperature setting is 37°C, and the inhaled oxygen concentration (FiO2) may be adjusted to a target of 93% or more of peripheral oxygen saturation (SpO2) in the range of 21 to 100%. After 24 hours, high flow oxygen therapy is discontinued and conventional oxygen therapy can be applied if necessary.
