How to properly set up the monitor before anesthesia surgery--Part 2

The previous article mainly explained the first two points of how to set up the monitor, and the next article explained the following points:

3. Connect the electrode pads/body medical temperature probe/body temperature sensor to monitor the patient's body temperature in real time.


Connect the electrode pads to each lead and stick the electrode pads to the corresponding positions. It should be noted that the position of the electrode pads should be adjusted according to the surgical incision site, disinfection range, and surgical position.

a. When skin damage, surgical incision, etc. affect the position of the electrode patch, select the adjacent skin;

b. Try to stay away from the disinfection range to prevent the electrode pads from being wet and causing poor contact;

c. In special positions such as side lying position and prone position, try to avoid the pressure of the electrode pads under the body, causing skin pressure injury and physical discomfort.

4. Adjust the pulse sound.

Why adjust the pulse sound?

This is because the tone of the pulse oximeter becomes sharper as the value increases and lowers as the value decreases. The tone of the oxygen saturation can also roughly determine whether the patient is hypoxic.

5. Change the alarm source for heart rate (“ECG” to “Pulse PLETH”).

Avoid interfering with the electrocardiogram when the surgeon uses the electrocautery, and the false arrhythmia will keep alarming and interfere with the attention of the anesthesiologist. Electrosurgery usually does not interfere with pulse oximetry.

6. Set the waveform interface and adjust the display of ETCO₂.

The above is all the steps.
