Research summary
This study is to investigate the changes in the volume of the nasal cavity and back of the throat after using a decongestant spray in patients with Obstructive Sleep Apnoea and a control population. These measurements will be made using a non-invasive acoustic reflection technique. The apparatus consists of a small plastic tube with a sound generator at one end and a disposable shaped plastic nose piece/mouthpiece at the other. Participants make a seal around one nostril/the mouthpiece and a microphone within the tubing detects reflected sound waves from the sound generator. The timing and amplitude of the sound wave that is reflected can be used to determine the dimensions of the airway.
