5. Study Description

Brief Summary
This study is a prospective randomised trial where a computer will randomly allocate patients to one of two possible methods of delivering oxygen during the procedure of bronchoscopy. This trial compares high flow nasal cannula (HFNC) with nasal prongs in delivering oxygen to patients undergoing endo-bronchial ultrasound guided trans- bronchial nodal aspiration (EBUS-TBNA) a specialised form of bronchoscopy procedure. HFNC uses humidified higher gas flow rates than conventional low flow systems such as nasal prongs which are limited by the respiratory rate and effort.
