我現在在讀EMT課程中間關於壓縮氧氣部分，裏麵的程序跟我們這裏實驗室不一樣。

EMT MANUAL:

1. remove protective seal

2. quickly open, then shut the valve ***This doesn't sound right...

3. attach regulator-flowmeter to tank

4. attach oxygen device to flowmeter

5. open flowmeter to desired setting

6. apply oxygen device to patient

7... turn off valve and remove all pressure from the regulator

LAB MANUAL:

...

Remove the cylinder cap  

Verify the cylinder valve is tightly closed

Attach the regulator and securely tighten 

Make sure the regulator working pressure is as low as possible by turning the pressure control knob counter-clockwise

Slowly open the cylinder valve and observe the high pressure gauge on the regulator as it climbs to full cylinder pressure

If no gross leaks (hissing sound) are readily observable, slowly open the valve to fully open (valves only seal properly when fully open or closed) 

Adjust to the desired working pressure by turning the pressure control knob clockwise, while observing the delivery pressure gauge for the desired setting 

結束程序是從氣瓶先關起，把氣放了再分解。
