The Patient monitor is often malfunctioning

1 Electrocardiogram shows that the electrode is missing or does not show the data waveform. Before using the multifunctional ECG Patient monitor, it is necessary to carefully check whether the electrodes are firm. (The skin needs to be cleaned before removing the electrode, and body hair should be removed, and the electrodes should be placed in a flat, muscle-free place) Whether the position is accurate, whether the lead has been connected wrongly, and whether the read lead used is correct. In clinical applications, 3 leads or 5 leads are generally used, but the Patient monitor instructions must indicate that the 5 leads should be connected at the same time. In the course of clinical application, we often encounter the phenomenon that the patient is turned over and the wire is distorted and pressed under the body, or the one-time electrode is expired during use and the electrode is dropped off or the data waveform cannot be detected. Therefore, in the clinical application process, Among them, it is necessary to adjust according to the actual situation, especially for patients who stay in bed for a long time. Because the skin is difficult to clean, it is necessary to wipe the adhesive site with warm water several times before it can be dried. The ideal time for one-time electrode replacement of a multi-functional ECG Patient monitor is usually 48 hours.

2 The non-invasive blood pressure test data has a large deviation or no indication. In the clinical application process, the measurement time often takes a long time, but the test result value is greatly deviated or there is no numerical display. Through careful observation and consultation of the relevant staff, the author discovered that the cause of the failure may be the hoses of the hoses and cuffs connecting the pipelines, which are caused by cracks and leaks due to aging. Aging occurs due to the use of the connectors for too long. , The connection is loose. Therefore, during the clinical use process, if the connector is loosened during aging, the loosened part of the connector must be cut off a little, and then connected, the interface of the new cut will be tighter; if it has been aging to be unusable, it can only be Replace with new ones. Sometimes it is due to the failure of the blood pressure module, which makes it impossible to analyze and convert the inflation pressure value. As a result, the measurement result cannot be displayed. However, this problem needs to be contacted by professional maintenance personnel for maintenance.

In clinical application, in order to ensure the accuracy of blood pressure measurement, we also need to pay attention to the fact that when measuring blood pressure, the patient's limb should be placed at the same level as its heart. Do not measure blood pressure on the infusion or catheter-attached limbs, and connect Patient monitoring. The inflatable tube of the instrument and blood pressure cuff must not be wrapped or knotted. The cuff should be wrapped around the patient's elbow at 1 to 2 cm. The degree of tightness should be such that 1 to 2 fingers can be inserted. Too loose may lead to high pressure measurement; too tight may lead to low pressure measurement. When continuously measuring blood pressure, attention should be paid to the circulatory disturbance caused by the cuff compression limb, and the measured limbs should be replaced within 6 to 8 hours.

3 Insufficient pulse oxygen detection In clinical use, there may be intermittent or non-exhaustive detection of pulse oxygen. The reason for this is considered to be due to the following reasons:

1 As far as possible, make a big thumb on the nail bed, followed by the forefinger and the middle finger, to avoid detection of small pinky fingers on the nail bed;

2 can not be in the Patient monitoring of blood pressure cuff side of limb detection;

3 can not be detected in the distal end of the bad finger;

4 Avoid putty nails and nails painted with nail polish;

5 blood oxygen probe to avoid use under strong light, if unavoidable, opaque fabrics can be used to cover the blood oxygen probe to avoid interference with measurement of blood oxygen caused by strong light, resulting in inaccurate measurements.

The clinical application of the multi-function ECG Patient monitor has increased the success rate of clinical rescue, but also reduced the workload of the medical staff, so it is welcomed by patients and medical staff. However, in the course of clinical application, there are often some operational problems or improper use, which will seriously affect the observation and treatment of clinical conditions. Therefore, it is very important for clinical staff to use multi-function ECG Patient monitor correctly.
