The dre anesthesia machine detects air leakage before use

　　The dre anesthesia machine, also known as the anesthesia machine, can accurately control anesthesia concentration and provide stable oxygen inhalation to help doctors ensure safe ventilation for patients during surgery. Doctors can ensure the safety of patients during anesthesia. The preparation for anesthesia machine is the first prerequisite for ensuring that the instrument can safely and stably assist doctors in performing anesthesia.

　　The most important part of preparing for anesthesia machine is the dre anesthesia machine's gas leak detection. This includes air leakage in the anesthesia line, in the anesthesia breathing circuit, and in the dre anesthesia machine.

　　Because gas leakage in the dre anesthesia machine is generally difficult to detect and can't be solved by non-professionals, doctors can basically observe the appearance and hints when using the machine, rather than having to disassemble the outer casing for testing. Connect the dre anesthesia machine's air supply tube to the oxygen supply terminal. Gently shake the air supply hose near the central oxygen plug to make sure there are no high pressure gas leakage sounds. Observe whether the needle of the oxygen source pressure gauge on the dre anesthesia machine is pointed at 0.4MP, or whether the needle is in the middle of the "green" range of the pressure gauge and held still. Near the back of the dre anesthesia machine, listen for a "b---- bared" air leak inside the machine. If there is no abnormal sound, air leakage in the anesthesia circuit is detected.

　　The anesthesia circuit test needs to determine that the anesthesia circuit is "locked" and ensure that the ACGO switch is turned off. First of all, insert the Y-tee of the anesthesia pipeline into the plug of the anesthesia circuit, connect the manual skin bag, install the sodium lime tank, and switch the wrench switch of the anesthesia circuit to the "manual" position, at this time the instrument screen is also displayed as manual mode. Close the APL valve, turn off the flow meter, and make sure the airway pressure gauge pointer in the dre anesthesia machine loop points to "0." Use the "rapid oxygen supply" switch to pump air, you can see the manual bladder gradually expand, observe the airway pressure gauge pointer rises to about 30cmH2O, relax the rapid oxygen supply switch. At this time, the entire anesthesia circuit is filled with gas, observe the airway pressure gauge for more than 10 seconds, the pointer has been at rest (the pressure does not drop), indicating that there is no leakage in the anesthesia circuit and pipeline. If the pointer slowly falls, it means that there is a small amount of leakage in the loop, should first check whether each connection interface is tightly plugged and closed, if necessary, you can use a hose to short-circuit the inspiratory and expiratory interfaces of the loop to eliminate the leakage of the anesthesia pipeline. Common loop leakage locations include sodium lime tank part, one-way valve seal ring, manual pouch, and water cup not tightened, and airway pressure gauge can be inserted.

　　The manual air leakage test was passed, and the APL valve was used for gas release in the anesthesia circuit, confirming that the use of the APL valve was normal. Then turn the wrench to the "machine control" position, and the instrument screen will also switch to the machine control icon. Connect the anesthesia line to the manual capsule, and use the quick oxygen button to raise the seal to the highest level, while the manual capsule also expands. When using the fast oxygen supply switch to supply air to the circuit, observe the pointer on the pressure gauge of the air source, and the degree of fall should not be lower than the green safety range of the dial. Perform machine-controlled simulated ventilation according to the set parameters of the instrument, and observe whether there is any abnormality in the movement of the bellows folded sac of the instrument. The top of the bellows hood can indicate that there is no air leakage in the machine control state every time the folded sac rebound. Then observe whether the ventilation value monitored by dre anesthesia machine is consistent with the set value. Air leakage in the machine controlled ventilation is sometimes caused by the failure of the anesthetic evaporator to be firmly placed in the bypass valve, or the aging of the support seal ring, and the cover of the evaporator dosing port is not tightened.

　　Air leakage detection before anesthesia machine operation is the most important thing to ensure the safety of anesthesia during surgery. Once air leakage occurs during surgery, it is almost impossible to stop the detection, which may lead to serious consequences. The after-sales department will receive an annual report of intraoperative faults related to dre anesthesia machine leakage, and these faults are related to the operator's failure to perform a complete dre anesthesia machine leak detection before surgery.
