NIVOAD Study: Non Invasive Ventilation in Obstructive Airways Diseases Study

This study compares two types of breathing support masks (non-invasive ventilation, or NIV) used in the emergency department for people having a moderate to severe asthma or COPD attack. Both masks help push air into the lungs without needing a breathing tube. The study aims to find out which approach works best. You may be eligible if: - You are 18 years of age or older - You are being treated in an emergency department for a moderate to severe flare-up of asthma or COPD (chronic obstructive pulmonary disease) - Your breathing is laboured (rapid breathing, low oxygen levels, or difficulty speaking in full sentences) - Your doctor has decided that non-invasive ventilation is needed You may NOT be eligible if: - You are too drowsy or confused to cooperate or protect your own airway - Your breathing failure is caused by something other than asthma or COPD - You have an untreated collapsed lung (pneumothorax) - You need a breathing tube placed in your throat - Your medical team has decided to withhold or withdraw treatment Talk to your doctor about whether this trial might be right for you.
