The Effectiveness of High-flow Nasal Cannula After Extubation in Patients

The Effectiveness of High-flow Nasal Cannula After Extubation in Patients

Observe the current status of prolonged mechanical ventilation (PMV) patients using high-flow nasal cannula oxygen therapy (experimental group) or traditional oxygen therapy (control group) after extubation, and compare the differences in ventilator weaning rates between the two groups.

Record the ROX index (SpO2/FiO2/RR) at 2, 6, 12, and 24 hours after extubation in PMV patients and explore whether statistical methods can predict the weaning outcome within seven days.

Use statistical methods to analyze whether comorbidities in the PMV population affect ventilator weaning rates.

Inclusion Criteria:

• Patients over 20 years old and expected to undergo extubation.

Exclusion Criteria:

• Patients with tracheostomy who will use non-invasive or invasive ventilators immediately after extubation.
