Pneumoperitoneum machine principle:?
CO2 pneumoperitoneum machine is the main equipment for artificial pneumoperitoneum. The use of CO2 pneumoperitoneum machine can be injected into the abdominal cavity with medical CO2 gas, the gas will be separated from the abdominal wall and abdominal organs, forming a surgical operation space, when a predetermined pressure can automatically stop the gas intake, and maintain a certain amount of gas so that the abdominal cavity has been at a predetermined pressure. When the intra-abdominal gas pressure decreases during surgical operation (e.g., when there is a gas leakage or when the surgery requires suction, or when the CO2 gas sucked out of the abdominal cavity during the extracorporeal rolling or when the abdominal pressure decreases due to leakage), the CO2 pneumoperitoneum machine can be inflated automatically in order to maintain the necessary space required for surgical operation.

Operating Procedures and Frequently Asked Questions?
Pressure presets: generally 12-15mmHg (adults), 7-9mmHg (children)?
The maximum must not exceed 15mmHg!
Flow preset value: when doing pneumoperitoneum with a pneumoperitoneum needle: 3-5l/min?
After connecting the perforator: 10-20l/min.?
(You need to turn off the air inlet switch to reset the value before pressing the air inlet switch)?
I: pneumoperitoneum machine common problems:?
1Air intake of the pneumatic machine is slow!
Principle analysis: pneumoperitoneum machine air intake is divided into two stages: pneumoperitoneum with pneumoperitoneum needle to do pneumoperitoneum; after doing pneumoperitoneum connected to the puncture device to maintain pneumoperitoneum.?
The first stage: with the pneumoperitoneum needle to do pneumoperitoneum, from the pneumoperitoneum needle's air inlet hole is only 1mm in diameter can be known: no matter how high you set the flow rate! The actual flow rate of the pneumoperitoneum with the pneumoperitoneum needle will only jump between 0.5-2l/min, and this value can be obtained by connecting the pneumoperitoneum needle to the glove test. Therefore, the actual flow rate of 0.5-2l/min is a normal and safe value when doing pneumoperitoneum with a pneumoperitoneum needle! It usually takes 5-8 minutes to do pneumoperitoneum!
Since the actual flow rate when doing pneumoperitoneum is only 0.5-2l/min, it is recommended to set the flow rate at this stage of the pneumoperitoneum with the pneumoperitoneum needle to 3-5?l/min to avoid problems when the peritoneum is not pierced!
