In intensive care and operating room environments, one of the most important parameters used to ensure the safety of the airway provided by endotracheal intubation is cuff pressure. Uncontrolled high or low pressure can cause serious complications. This is where the Endotracheal Tube Cuff Pressure Meter comes into play, a critical medical device that helps keep the pressure in the tube cuff at the ideal range during intubation. An endotracheal tube is an airway device that is placed in the trachea and provides mechanical ventilation. The inflatable bubble called "cuff" at the end of the tube contacts the tracheal wall, preventing leakage and providing a stable airway. It may cause tissue ischemia, ulcer and stenosis development by compressing the tracheal mucosa. Therefore, keeping the cuff pressure within the range of 20–30 cmH₂O is of great importance for patient safety. Cuff pressure measuring devices are generally portable, manometer-controlled and manually controlled mechanical equipment. The measurement process is done as follows:
