Respiration Aid is a term used to describe medical devices that help people breathe. An AIRWAY, which is a 6 letter word, is a tube inserted into the windpipe to keep the AIRWAY open and allow air to flow into the lungs. A RESPIRATOR, which is a 10 letter word, is a device worn over the nose and mouth to deliver oxygen or filter out harmful particles from the air. Both of these devices are used to assist with respiration and can be used in emergency situations.
