Eligibility
Inclusion criteria
Inclusion criteria: - Aged >= 18 years - Receiving invasive mechanical ventilation >48 hours for any cause - Scheduled for extubation as per local clinical guideline - Provided informed consent
Exclusion criteria
Exclusion criteria: - Any clinical situation preventing appropriate execution of study procedures, such as; o Severe agitated delirium o Do not reintubate order - The presence of a tracheostomy - Respiratory acidosis, defined as a pH 6.5 kPa / PCO2 > 50 mmHg) during or after SBT - Any feature that prohibits HFNO-initiation o Recent facial upper-airway surgery o Anatomic abnormalities that preclude appropriate fitting of HFNO cannula o Current exacerbation of obstructive pulmonary disease - Obstructive/central Sleep Apnoea Syndrome or Obesity Hypoventilation Syndrome in medical history - Contra-indication for nasogastric tube or inability to perform adequate PES measurements, e.g.: o Recent esophageal surgery o Prior esophagectomy o Known presence of esophageal varices o Severe bleeding disorders - Known diaphragm paralysis defined as elevated hemi-diaphragm on X-ray or evidence of paralysis during ultrasound (i.e. paradoxal diaphragm movement during sniffing) - Known pregnancy or current breast-feeding
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main outcome is the difference in change in lung respiratory muscle effort (mean ΔPES) at 24 hours post-extubation between the study groups. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary parameters are differences in changes in respiratory effort at 2 and 4 hours post-extubation, difference in change in lung aeration (mean ΔEELI), differences in tidal volume, Lung Ultrasound (LUS) score, dyspnea score, and respiratory and sputum parameters between patients undergoing different post-extubation oxygenation regimens. | — |
