Use ECG monitor, need to pay attention to the problem

Clinically different brands and functions of the ECG monitor may use a slightly different way today Xiaobian to Ruibo ECG monitor as the object, to talk about the correct use of ECG monitor method.

The use of ECG monitor object

Any critically ill patients are required to continuously monitor the frequency of heartbeat, rhythm, breathing, blood pressure, pulse and percutaneous oxygen saturation and other patients.

The location of the electrodes placed

There are five electrodes placed as follows:

Right upper (RA): sternal right margin clavicle midline intercostal space.

Right lower (RL): right clavicle midline xiphoid level.

Middle (C): sternal left margin of the fourth intercostal space.

Left upper (LA): sternal left margin clavicle midline intercostal space,

Lower left (LL): left clavicle midline xiphoid level.

Monitor manufacturers

Operating procedures

Prepare items: mainly ECG monitor, ECG plug-in connection wire, electrode tablets, saline cotton ball, supporting the blood pressure cuff.

The operating procedures are as follows:

1. Connect the ECG monitor power supply.

2. Patients should be supine or semi-recumbent.

3. Open the main switch.

4. Wipe the skin of the patient's chest with a saline ball.

5. Stick electrode, connect the ECG line, the screen ECG show

6. Tighten the cuffs to the two cubits at the elbow. Press Measure - Set Alarm Limit - Measure Time.

Different functions of care should pay attention to matters

Precautions when handling ECG

1. Remove the ECG lead wire, the lead wire plug on the front panel of the host "ECG" jack groove, insert the

2. ECG lead with the other end of the five electrode head connected with the measured body, the correct connection steps are:

a. With 75% ethanol to measure the surface cleaning, the purpose of removing the human skin on the stratum corneum and perspiration, to prevent poor contact with the electrode.

b. The electrode tip of the ECG lead wire is fastened to the electrode of the five electrode tabs.

c. After evaporation of ethanol, the five electrode pieces will be affixed to the specific location after cleaning to make it reliable and not fall off.

d. Stick the skirt on the lead line in the bed. And told the patient and health care workers do not pull the electrode line and lead line.

3, be sure to connect the ground, which will play a normal display of the waveform is very important role.

Precautions for blood pressure monitoring

Blood pressure cuff connection with the patient, for adults, children and newborns are different, you must use different specifications of the cuff, where only adults as an example.

1. Cuff after the start should be wrapped around the elbow in the patient 1 ~ 2cm Department, the degree of tightness should be able to insert 1 to 2 refers to the appropriate. Too loose may lead to high pressure; too tight may lead to low pressure, while the patient will not comfortable, affecting the patient's arm blood pressure recovery. The catheter of the cuff should be placed at the brachial artery and the catheter should be on the extension of the middle finger.

2. arm and the human heart should be flush, blood pressure cuff inflatable should instruct patients not to talk or tamper with.

3. When the pressure, the position of the cuff on the arm and the heart should be flush, the patient should not speak or move.

4. Pressure arm should not be used to measure body temperature, will affect the accuracy of body temperature values.

5. Do not drip or have a malignant wound, otherwise it will cause blood reflux or wound bleeding.

6. In general, the first manometry is for reference only

Precautions when monitoring blood oxygen

1. Oxygen probe plug and host panel "blood oxygen" jack must be plugged in place. Otherwise it may not be able to collect blood oxygen information, can not show blood oxygen value and pulse value.

2. require the patient nails can not be too long, can not have any dyes, dirt or onychomycosis. If the blood oxygen monitor for a long time, the patient's fingers will feel discomfort, should replace the other finger to monitor.

3. Patients and health care workers should not bump and pull the probe and wire to prevent damage and affect the use.

4. Blood oxygen probe placement should be separated from the blood pressure arm, because the blood pressure measurement, blocking blood flow, and this time can not detect blood oxygen, and the screen shows "blood oxygen probe off" words

External power supply precautions

1. Power distribution box should be excellent and reliable texture, plug should be reliable. So as to avoid the bad plug, so that the host can not work properly, and even cause damage to the host power supply.

2. To power supply uninterrupted, stable for the principle.

The main observation of ECG

1. Regularly observe and record heart rate and rhythm.

2. Observe whether there are P waves, P wave shape, height and width of how.

3. Measure P-R interval, Q-T interval.

4. Observe whether the QRS waveform is normal or not.

5. observe whether the T wave is normal.

6. Note whether the abnormal waveform appears.
