Problems and Countermeasures in the application of monitor

Monitor is a kind of electronic medical equipment which can monitor one or more parameters of human body and make a timely judgment of its health. It is a kind of electronic medical equipment which can continuously monitor the frequency, rhythm, respiration, blood pressure and oxygen saturation of cardiac pulse in critical condition. Monitor is widely used in clinical departments, so that medical staff can more easily and quickly understand the dynamic changes of patients. In order to better serve patients, nurses should master the monitor fault, alarm and maintenance.

Common problems and troubleshooting in 1 ECG monitoring

ECG signals are obtained by body surface electrodes, so it is necessary to ensure the normal connection of ECG monitor cables in order to obtain the correct measurement value. Therefore, good contact between skin and electrodes should be achieved. (I) lead fall off: (1) electrode fall off; second, lead wire and electrode fall off. Processing: 1. Change the electrode, electrode connection can cause any form of electrocardiogram interference, the application of the electrode place to do a good job of skin cleaning, if necessary, with 95% alcohol wipe the skin. Besides, avoid the location of electrocardiogram, electrodefibrillation and pacemaker. (2) Stress loop stabilization, in order to minimize the electrocardiogram artifacts, lead wire on the electrode tension or lead rotation, the lead wire will be wound into a loop, the lead wire is wound into a ring of stress, can ease the lead wire on the electrode tension and prevent the lead wire rotation, with adhesive tape to the patient, can reduce a lot of stress loop Human failure. (2) baseline wandering is irregular, usually intermittent and continuous. Discontinuity is often caused by poor connection of electrodes, wires and wires. Continuous wandering is often caused by strenuous breathing, so it is necessary to closely observe the changes in the condition, find out the causes and make corresponding treatment. (3) electrocardiogram (ECG) interference is caused by patient agitation. Make the patient take comfortable position, the environment is quiet and comfortable.

2 common problems of noninvasive sphygmomanometer

(1) Non-invasive blood pressure pump timeout, due to the patient's movement, cuff placement is not correct, cuff over the normal time or detected air leakage and other factors. Carefully check whether the connection of the cuff pipe line is leaking, if there is no air leakage, reposition the cuff at the correct position. (2) Factors affecting blood pressure values: 1. The patient's body position, so that the measured limbs and the patient's heart at the same level. Select suitable cuff. 3. Patients' mood swings and agitation.

3 common problems in respiratory monitoring

The monitor usually uses impedance measurement to measure respiration, that is, to measure respiration according to the change of impedance of two electrodes in the chest. Respiratory parameters were abnormal, and the electrode position was checked. Two electrodes were placed diagonally to extract respiratory information in order to obtain the best respiratory wave. If the patient's condition affects the signal is weak, two electrodes are placed in the right axillary medial line and left thoracic side respectively to obtain the best respiratory wave.Meilun

At this point, we should closely observe the changes of the situation, and take measures in time if there is any abnormality.Meilun

4 problems in monitoring blood oxygen saturation

(1) Oxygen saturation changes rapidly, signal intensity wanders uncertainly, may be due to excessive displacement of patients, try to use patients quiet and less active. (2) The patient's perfusion was too low to measure the oxygen saturation and observe the changes of the disease closely. In clinical work, the monitor suddenly does not work or the display is not bright, most of them are poor contact with the power cord, or all the batteries are exhausted, so the monitor is cleared in time after using up; maintenance and debugging, so that it is in a good standby state. Strict implementation of operating procedures, constantly sum up experience, to provide quality services for patients.
