Check the date of the oxygen pipe, check for leaks, connect the oxygen pipe and the humidification bottle, and connect firmly, turn on the oxygen switch, and adjust the oxygen flow. Connect the oxygen tube and mask to ensure that the connection is tight and will not fall off.

After adjusting the flow rate, cover the mouth and nose with an oxygen mask and adjust the tightness. Timely record oxygen inhalation time and oxygen flow. Observe the oxygen inhalation status, and shut down in time if there is an abnormal state.


When the oxygen consumption time is reached, close it in time, remove the mask, turn off the flow meter, record the time when oxygen is disabled, and wash your hands.

First, they require the use of air hoses to provide air to provide power. This means that the point power cord for pneumatic tools will be thicker, heavier and less flexible than power tools. However, the coiled air hose can improve this situation. The coiled air hose can make the pneumatic tool more convenient, which is very suitable for low-power desktop tools.
Second, the air inlet of the pneumatic tool needs to be lubricated frequently. The air sent into the tool must be filtered and lubricated to prevent premature wear of the pneumatic tool, and maintenance and repair are more troublesome.
Third, pneumatic tools may generate more noise when they are used. This is because the air is discharged from the exhaust port on the tool, and this process generates some noise.
Most importantly, the cost of pneumatic tools is generally higher than pneumatic tools. First of all, the price of pneumatic tools themselves is higher; second, the use of...    less
