Just four o'clock, teach you to take care of the monitor

NO.1 electrode problem

1. Common chest bipolar lead monitoring, choose the ideal location, and choose to monitor, surgery or diagnosis to give the filter, ECG should make the waveform clear, easy to analyze arrhythmia.

2. Positive pole is located below the negative, to avoid auscultation and defibrillation position, to avoid friction and frequent activities of the site, surgery to avoid the electric knife output line.

3. Proper placement of ECG electrode position, the electrode should have a rich and rich conductive paste and smooth lead wire connector.

4. skin is not clean or too much hair, dander can lead to poor electrode contact, pay attention to clean the skin, if necessary, 75% alcohol wipe the skin.

5. Replace the electrode every 24 hours or change the position.

6. You can not use expired or reusable disposable electrodes.

7. Surgical equipment such as electric knife, electric condenser, suction device, surgical space electromagnetic field and other often interfere with ECG oscilloscope.

8. The interference waveform is not filtered.

9. Patients with muscle tremor or body movement can also interfere with the identification of the waveform.

10. Install patient with pacemaker, use the monitor heart pacing analysis Click to turn on, and turn on the limit wave.

NO.2 Respiratory monitoring problems

1. Monitor manufacturers measurement principle: chest impedance method (breathing process of thoracic movement, resulting in changes in human resistance, impedance values of the map to describe the dynamic waveform of breathing can show the respiratory rate parameters, vulnerable to interference)

2. It is advisable to route the two breathing electrodes RA and LL through the area of maximum activity during breathing to obtain the best respiratory wave.

3. Avoid the liver and ventricle on the breathing electrode white RA and red LL connection. This avoids the artifacts caused by cardiac coverage or arterial blood flow.

4. Respiratory care is not suitable for patients with a large range of activities, as this may lead to false alarms.

NO.3 No problem of noninvasive pressure monitoring

1. Measurement principle:

Oscillation method (with cuff inflation to a certain pressure to completely block arterial blood flow, with the pressure decreases, the arterial blood flow will appear completely blocked - gradually open - fully open, the arterial wall of the pulse will be generated in the cuff Shock waves produce the first and most clear signal - which can reflect SBP, when the amplitude of the shock reaches the peak - can reflect the MAP, when the pressure in the cuff suddenly decreases - can reflect DBP)

2. Select the appropriate sleeve and mode settings, cuffs are divided into adult mode and pediatric mode.

3. mark ∮ aligned brachial artery, the degree of tightness can only reach into a finger prevail.

Just four o'clock, teach you to take care of the monitor!

4. Cuff should be at the right atrium level and outreach 45 degrees.

5. The patient is moving, shaking or spasm, the measurement will be error.

6. Unless the disease needs, do not have to measure blood pressure frequently, according to the timely adjustment of blood pressure measurement interval.

7. Measurement of blood pressure changes rapidly, the measurement will be error, or even not measured blood pressure.

8. Can not wear too thick clothes, especially cotton sweater.

9. When the heart rate is lower than 40bpm and higher than 240bpm, the result will be measured.

10. The patient is in severe shock or the body temperature is too low, the pressure will be error, because the flow to the periphery of the blood flow will lead to reduced arterial pulsation.

11. Severe blood pressure (systolic blood pressure over 270mmHg) or severe hypotension (systolic blood pressure below 50mmHg) measurement results will be error.

12. severe heart rate disorders.

13. Blood pressure can not be adjusted when measuring blood pressure.

14. Check out or wait for the patient into the department, to avoid the blood pressure meter empty charge measurement, timely press the blood pressure key to stop measuring.

NO.4 Monitoring of oxygen saturation

1. Measurement principle:

Pulse method (with a certain wavelength of red light 660nm and infrared light 940nm) through the measured tissue, the pulse wave through the measured tissue, by measuring the pulse wave crest and trough absorbance changes calculated SPO2).

2. Place the sensor in the proper position of the patient's finger.

Just four o'clock, teach you to take care of the monitor!

3. Can not keep the same part for a long time.

4. Do not use the oximeter probe on the same arm as the blood pressure cuff.

5. Improper sensor installation or improper contact with the limbs.

6. When the light is irradiated onto the oxygen probe, the light receiver can deviate from the normal range, resulting in inaccurate measurements.

7. distal cycle difference, such as shock, finger temperature is too low, will lead to the arterial blood flow measured to reduce the measurement is not allowed or not measured.

8. ipsilateral measurement of blood pressure, or lateral position compression side, affecting microcirculation, resulting in the results are wrong.

9. nail nail polish, will affect the light through, resulting in measurement difficult.

10. Measure the oxygen saturation of the distal toe if necessary.
