Combination of High-flow Nasal Oxygen (Optiflow) and Vibrating Membrane Nebuliser (Aerogen) in the Pre-hospital Setting - Before/After Study

NCT07791992

WithdrawnN/A

Sponsor: Centre Hospitalier Sud Francilien

Conditions: Hypercapnia, Asthma Exacerbation, COPD Exacerbation

Interventions: Vibrating membrane nebulizer and high-intensity nasal oxygen, nebulizer mask and oxygen therapy of 6 to 9 liters per minute

Countries: France

The aim of this observational before/after study is to determine how to optimally administer oxygen to patients experiencing an asthma or COPD exacerbation in emergency medical services. The aim will be to determine which method will achieve the target oxygen saturation objectives: \> 95% in asthma exacerbations and between 88% and 92% (or \> 92% in ambient air or with FiO2 21%) in COPD exacerbations. The study will compare a group "before" receiving standard care with a nebulizer mask to a group "after" using a combination of a vibrating membrane nebulizer and high-flow nasal oxygen.
