Abstract
The disclosure relates to an airway maintenance device, such as an endotracheal tube, tracheostomy tube, or supraglottic airway device, and in particular to an airway maintenance device having a sensor for measuring capillary blood flow and/or pressure. The device includes an airway maintenance device with an airway lumen having a proximal end and a distal end, a distal end portion incorporating an optical sensor configured to measure capillary blood flow in tissue surrounding the distal end when in position within a patient's airway. The optical sensor may include a portion of an optical fibre extending to the distal end portion along the lumen.
