The tracheal cannula cuff is an important part of the tracheal cannula, and the cuff is inflated after the cannula so as to isolate the artificial airway from the oropharynx. The low pressure of the cuff can cause ventilation and air leakage, insufficient tidal volume, mistaken aspiration of airway secretion or digestive juice, failure of lung isolation, incapability of performing chest operation and the like. The pressure of the cuff is too high to press the tracheal wall of a patient, and the critical conditions such as mucosa necrosis, tracheal stenosis or tracheal laceration caused by blocking the blood supply of local mucosa are avoided.
Currently, a pressure measuring device is manually used for measuring pressure and adjusting the pressure of the cuff every several hours clinically. In actual work, the emergency cannula sleeve is inflated rapidly, laughing gas is used in operation, the trachea cannula is shifted, and the like, so that the pressure of the sleeve is possibly increased, or the head and neck position is changed, the pressure of the sleeve is abnormally reduced due to factors such as leakage of the sleeve, and the like. The traditional cuff monitoring mode cannot ensure that the safe pressure of the cuff is reached rapidly and once in the process of rapidly inducing intubation. Known cuff pressures are below 20cmH 2 O may cause air leakage, exceeding 40cmH 2 O can cause ischemia injury of tracheal mucosa after exceeding 15 minutes. Related researches all find that after the operation of the intubation in emergency treatment, ICU and operating room>50-80% of patients have immediate cuff pressure greater than 40cmH 2 O.
