How to use the pet breathing anesthesia machine? Please, 3Q.

Warning: When using this method, doctors should have certain clinical anesthesia experience, be familiar with anesthesia machine, and have certain parameters such as blood pressure, blood oxygen and ECG monitoring. Before operating the instrument, please ensure that the indoor temperature is between 17-25 degrees Celsius. 1, the first step is to connect the oxygen pipeline, first open the oxygen cylinder table (high range table), and then open the oxygen decompression table table (low range table), and the second step is to adjust the pressure between 0.4 MPa and 0.45 MPa. 2. Connect the breathing pipeline of the anesthesia machine, and connect both ends of the Y-shaped tee and the right-angle crank to the front of the breathing sac. 3. Check the amount of anesthetic (enflurane or isoflurane) in the evaporator to ensure that the dose is sufficient to maintain the operation process. 4. Check the air tightness of the whole machine (see air tightness inspection method). 5. Set the "mechanical control/manual control" switch of the absorption loop to: manual control state, manual control state and mechanical control state. 6. Check the "APL valve", which must be in a half-open state. APL valve closed state APL valve semi-open state airway pressure gauge Note: The so-called "APL valve" semi-open state: turn the "APL valve" counterclockwise until it is turned to the bottom. 7. Adjust the knob of the flowmeter. The principle of adjusting the specific value of the flowmeter is to ensure that the manual bag is in place, and the bag does not deflate when the animal inhales, and the bag does not inflate when the animal exhales, which is the appropriate value. Flow meter knob inspiratory state expiratory state 8. Turn on the evaporator, turn on the evaporator to the maximum value of 3%VOL 9, and turn on the flowmeter to 2.0L/min for 30 seconds. 10, conduct animal-induced anesthesia, conduct anesthesia tracheal intubation (intravenous anesthesia is required to last for 3-5 minutes), connect the anesthesia machine to the animal-induced tracheal intubation, turn on the evaporator switch, adjust the concentration to 3%VOL, and observe the depth of anesthesia. Special attention: enter the anesthesia maintenance period, adjust the flowmeter to an appropriate value, turn on the evaporator to an appropriate concentration (different animals have individual differences), observe the anesthesia depth, and then fine-tune the concentration. After the anesthesia is stable, enter the anesthesia maintenance period and perform the next operation. Special attention: enter the anesthesia maintenance period, adjust the flowmeter to a suitable value, and turn on the evaporator to a suitable concentration. The evaporator concentration value is shown in the above figure: ① When the flow rate of the flowmeter is 0.8-3L/ min, the evaporator concentration is the above value (i.e. 0.5, 1, 2,3, etc. ); ② When the flow rate of the flowmeter is 0.2-0.8L/MIN, the concentration of the evaporator is the following values (i.e. 0.2, 0.5, 1.0, 2.0, etc.). ). 1 1, 12 The operation starts, and 5 minutes before the operation is completed, the concentration of the anesthesia evaporator is turned off, and other parameters are kept unchanged, and the operation continues. 13, when the animal's spontaneous breathing ability is relatively strong, it can pull out the trachea 14, and then turn off the air source. When turning off the gas source, first turn off the oxygen cylinder gauge (the gauge with high range), then turn off the oxygen decompression gauge gauge (the gauge with low range), and press the fast oxygen supply to release the excess gas in the machine. Note: This anesthesia method can be completed without power supply. Made by Beijing Ruide Company Pet Medical Division.
