An airway device 14, that is used to maintain a clear airway in a patient, e. g. for artificial ventilation during surgery, comprises an inflatable cuff 26, which is inflated when in position in a patient’s airway 24. The inflated cuff 26 provides a seal to maintain the device 14 in position in a patient’s airway 24, and to prevent leakage of infected oropharangeal secretions into the patient’s lungs. A method and apparatus 10 for monitoring and controlling the pressure in the inflatable cuff 26 is described, which, in one embodiment, controls the pressure about a setpoint pressure, whilst preventing loss of sealing pressure during a patient’s respiratory cycle. In other embodiments, the method and apparatus monitors for: leaks in the pressure system of the device 14 that includes the cuff 26 blockage in the pressure system, and/or malpositioning of the airway device 14 during use.一種氣道裝置14,用於維持病患氣道暢通例如用於手術中人工通氣,包含一充氣式臂袋26在病患氣道24位置充氣。充氣臂袋26提供一密封以維持裝置14在病患氣道24之位置,以及預防感染口咽分泌物滲漏進入病患肺部。一種方法與裝置10可用於監測與控制充氣式臂袋26壓力,於一實施例中控制設定點壓力之壓力值,同時於病患呼吸循環期間預防壓力密封狀態被破壞。其他實施例中,該方法與裝置可監視:包括臂袋26之裝置14之壓力系統其滲漏;壓力系統阻塞,以使用期間及/或者氣道裝置14之錯位。10‧‧‧裝置12‧‧‧氣道裝置12’‧‧‧延長線12”‧‧‧單向閥14‧‧‧氣道裝置16‧‧‧病患18‧‧‧氣道管20‧‧‧近端22‧‧‧遠端24‧‧‧氣管26‧‧‧臂袋
