Clinical Trial Summary

High flow nasal cannula administration in critically ill patients is frequently used to improve acute respiratory failure or to prevent respiratory failure after extubation.

It acts generating a mild positive pressure in the airways and by reducing respiratory effort of patients.

However to the best of our knowledge, no study to date has directly measured the amount of positive pressure generated in the trachea of patients.

The primary aim, therefore, of this study measures this positive pressure after extubation in critically ill patients.

Intervention

Device:
• HIGH FLOW NASAL OXYGEN
BEFORE EXTUBATION, AN AIRWAY EXCHANGE CATHETER (AEC) WILL BE PUT INTO THE PATIENTS' TRACHEA AND IT WILL REMAIN IN SITE AFTER EXTUBATION. THROUGH AN AEC CONNECTED TO A PRESSURE MONITOR, IT WILL BE RECORDED TRACHEAL PRESSURE DURING SPONTANEOUSLY BREATHING PATIENT AT DIFFERENT FLOW RATES OF HFNC THAT WILL BE APPLIED JUST AFTER EXTUBATION. MEANWHILE, VITAL PARAMETERS RECORDED WITH A MULTIPARAMETRIC MONITOR WILL BE RECORDED. FINALLY, MONITORING OF ELECTRICAL ACTIVITY OF DIAPHRAGM WILL BE RECORDED THROUGH A DEDICATED NASOGASTRIC TUBE TO EVALUATE IT AT DIFFERENT FLOW RATES.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	HFNC-PEEP	THE LEVEL OF POSITIVE AIRWAY PRESSURE GENERATED BY DIFFERENT FLOW RATES OX OXYGEN WILL BE RECORDED.; FLOW RATE STARTS AT 10 L/MIN AND IT WILL BE INCREASED A 10 L/MIN STEP EVERY 30 MINUTES UNTIL 60 L/MIN.	3 HOURS
Secondary	HFNC-EADI	ELECTRICAL ACTIVITY OF THE DIAPHRAGM WILL BE RECORDED THROUGH A DEDICATED NASOGASTRIC TUBE DURING ALL THE PROCESS.; FLOW RATE STARTS AT 10 L/MIN AND IT WILL BE INCREASED A 10 L/MIN STEP EVERY 30 MINUTES UNTIL 60 L/MIN.	3 HOURS
