Background
In clinical diagnosis and treatment, mechanical ventilation is assisted by a breathing machine to maintain the airway unobstructed, improve ventilation and oxygenation, prevent hypoxia and carbon dioxide accumulation of the body, create conditions for the body to possibly overcome respiratory failure caused by basic diseases and treat the basic diseases.
In the mechanical ventilation process, the transpulmonary pressure is an important reference index of positive pressure ventilation setting in respiratory support, and can be used for measuring lung compliance and lung resistance. Transpulmonary pressure is equal to the difference between the intra-pulmonary pressure and the intra-thoracic pressure. The intrapulmonary pressure can be measured directly via an endotracheal tube. Regarding the measurement of intrathoracic pressure, it is currently accepted to estimate intrathoracic pressure as esophageal pressure, and the difference between the two in absolute value is related to esophageal wall tension, esophageal surrounding structures, and physical properties of the measurement system, but the relative changes of the two are very consistent.
Esophageal pressure is usually obtained by measuring the pressure in the lower esophagus. Clinically, in order to measure the esophageal pressure, an esophageal piezometer tube with a cuff is generally placed in a gastric cavity, the cuff is inflated with about 0.5ml of air and then connected with a pressure sensor, and then is slowly pulled out.
This operation is comparatively loaded down with trivial details, and need possess certain experience, and the gained data change degree of different operators is great. Generally, the fixing of the position of the pressure measuring instrument has high requirements for operators, and if the pressure measuring point on the pressure measuring instrument cannot be well positioned, a relatively large error is generated in the value of the measured esophageal pressure. In addition, the pressure measuring tube is used to measure esophageal pressure, and some locations in the abdomen (such as stomach, cardia, etc.) are often monitored simultaneously to control esophageal reflux or abnormal changes in the intra-abdominal pressure, which affects ventilation operation and measurement results. In addition, the pressure measuring tube also requires a relatively simple processing function such as suction or infusion for a certain amount of factors that may cause pressure fluctuations or reflux in the abdomen.
Therefore, there is an urgent need in the art to develop an apparatus for performing thoracoabdominal manometry which is easy and convenient to operate, accurate in positioning, and accurate in data measurement.
