The present invention relates to a system () for monitoring one or more physiological parameters of an individual. The system () comprises an optical fibre assembly () configured to measure one or more physiological parameters of an individual, and a pressure sensor () configured to measure a contact pressure of the optical fibre assembly () on the individual. The pressure sensor () comprises an optical fibre () comprising a transducer fibre Bragg grating () embedded in a matrix (). The matrix () is configured to cause longitudinal strain in the transducer fibre Bragg grating () in response to the matrix () being subject to a transverse load. The one or more physiological parameters that the system () is for monitoring may include blood oxygen saturation (Sp O2), capillary refill time (CRT), heart rate, blood flow and CO2 emissions from skin.

Monitoring physiological parameters

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.
