NCT06379607

Brief Summary

This is a randomized, open-label, 3-armed feasibility trial will examine conventional oxygen therapy (COT) vs high flow nasal cannula at 4L/min flow vs HFNC at 2L/kg/min flow (max 60L/min) in moderate to severe pediatric asthma exacerbations.

Study Arms (3)

Conventional Oxygen Therapy (COT)

NO INTERVENTION

Conventional Oxygen Therapy (COT) is the standard way to deliver oxygen to hypoxemic pediatric patients during an acute asthma exacerbation. Continuous albuterol will be administered via an aerogen set-up (aerogen mask, aerogen ultra, and a vibrating mesh nebulizer). Oxygen tubing will be connected to the wall and run at 2L/min as per the aerogen manufacturer's instructions.

"Low Flow" High Flow Nasal Cannula at 4L/min

EXPERIMENTAL

A Fisher Paykl humidifier will be used for high flow humidification along with a flow meter and oxygen blender. A vibrating mesh nebulizer will be connected between the flow meter and the humidifier as per routine practice. Oxygen flow will be set to 4L/min and patient will be fitted with appropriately sized nasal prongs.

Device: "Low Flow" High Flow Nasal Cannula

"High Flow" High Flow Nasal Cannula at 2L/kg/min (max 60L/min)

EXPERIMENTAL

A Fisher Paykl humidifier will be used for high flow humidification along with a flow meter and oxygen blender. A vibrating mesh nebulizer will be connected between the flow meter and the humidifier as per routine practice. Oxygen flow will be set to 2L/kg/min (max 60L/min) and patient will be fitted with appropriately sized nasal prongs.

Device: "High Flow" High Flow Nasal Cannula

Interventions

High Flow Nasal Cannula will be applied in both experimental groups but different flow rates will be used in each arm; this arm will use higher flow rates.
