Description

dynamic monitoring of cuff pressure

technical field

The utility model relates to the technical field of medical supplies, in particular to a dynamic monitoring air bag pressure.

Background technique

Tracheal intubation and tracheotomy are one of the important means to save the lives of patients in emergency situations, and play an important role in the rescue, resuscitation and treatment of critically ill patients. The fixation of the catheter is an important means to block the patient's airway through the appropriate pressure of the balloon, ensure positive pressure ventilation of the ventilator, reduce aspiration of secretions, and prevent accidental detubation. If the air bag pressure is too high, it will reduce the blood perfusion of the tracheal mucosa, and may even cause tracheal bleeding, tearing or fistula formation. If the air bag pressure is too low, it may cause aspiration, increase the risk of ventilator-associated pneumonia (VAP), and lead to an increase in patient mortality.

Clinical guidelines recommend the use of a balloon pressure gauge to measure the patient’s balloon pressure and maintain the balloon pressure within the range of 25-30cm H ₂ O. In the current use process, medical staff directly use syringes or manual pressure gauges to inflate, which cannot be accurately monitored and monitored. Controlling pressure that is either too high or too low can cause patient safety issues.
