Understand the standard setting of alarm upper and lower limits of ECG monitor

ECG monitor has the characteristics of high accuracy, usefulness and convenience. ECG monitor can monitor the vital signs of patients in time and provide basis for clinical diagnosis and treatment. An alarm will appear when a value monitored by the monitor exceeds or fails to reach the upper and lower limits set beforehand. In the meantime, improper use of alarm will improve the error information, not only affect the workload of medical staff, affect the monitoring role. Therefore, the standard setting of ECG monitor alarm upper and lower limits, can effectively reduce the occurrence of false alarm, improve the quality of work, to ensure the safety of patients.

1. The setting principle of monitor alarm.

1. ensure patient safety.

2. alarm volume setting is necessary to ensure that nurses can hear them in the scale of operation.

3. Do not allow the closed alarm function, unless the patient is in terminal condition, the family abandoned rescue and treatment; is being rescued can also temporarily closed the alarm.

4. the setting of alarm scale is not normal, but should be safety scale.Meilun

5. the alarm scale should be adjusted at any time according to the situation. At least every class should check the setting once or not. In time of shift, adjust in time.

6. during transit, the alarm setting on the transfer monitor must be the same as bedside monitor.

7. nurses are required to handle yellow and blue alarms in 20S and red alert in 5S.Meilun

Two. Alarm parameters

1. Heart rate: 10% - 20% of its heart rate. The lower limit should not be lower than 40 times / min, the upper limit should not be higher than 150 times / min. Wave speed 25mm/s.

2. Blood pressure: Set the scale according to the doctor's instructions, if there is no specific requirement, set SBP 90-140 mmHg, DBP 60-90 mmHg, MAP 70-110 mmHg according to the normal scale. Patients with hypertension, craniocerebral surgery, cardiovascular and cerebrovascular diseases, according to doctor's instructions. Wave speed 25mm/s.

3. finger pulse oxygen saturation: the upper and lower alarm limits are set at 90%-100%, or set according to the condition. Example: COPD patients are set to 85%-100%, wave velocity 25mm/s..Meilun

4. Respiration: 10% - 20% of the breath itself. Normal breathing, the lower limit should not be less than 8 times / minute, the upper limit should not be higher than 30 times / minute. Wave speed 6.25 mm/s.

Three, the comfort degree of the progressive guardianship patients.

1. accurately assess the patient's condition, and provide dynamic activity guidance based on illness and treatment needs. The wires should be placed in a regular and moderate manner, so as not to affect the bed movement.

2. Patients admitted to the condition can extend the interval of blood pressure measurement at night and replace the position of pulse oxygen clip every 2 hours.

3. Look at the skin at the electrode every shift. Replace the electrode position every 48 hours. If skin allergy occurs, replace the electrode position.

4. strengthen communication between nurses and patients so that patients can understand the importance of guardianship for diagnosis and treatment of diseases.

Four, relieve medical staff fatigue warning strategy

1. Reduce false alarm or magnetic disturbance alarm: Improve the signal quality, replace the electrode every day, correct the alarm settings, and strictly grasp the ECG monitor application indicators.

2. Strengthen continuing education: Nurses are the primary instrument operators and alarm handlers, nurses should be aware of the importance of alarm and proficiency in the correct operation of the instrument, are dependent on useful continuing education.

3. optimizing alarm notification system

Five, effect

1., the professional level of nurses has been improved, and the quality of care for critical patients has been ensured.

2., nurses have improved their management ability and promoted the continuous improvement of nursing quality.

3., nurses have improved their work enthusiasm and improved their efficiency and execution.
