What factors can cause the monitor to be faulty?

However, in clinical work, we sometimes encounter such a problem: the monitor alarm, when we came to the patient side, found that sometimes only false positives, the patient did not appear any unusual. This meaningless alarm, as if the "wolf" story, happened more, and finally let us have a sense of burnout, over time the trust has also been a threat.

What is the current status of the alarm?

Wu Jun and a survey, ICU monitor the average number of alarm 37 times, as early as 7: 00 ~ 19: 00 average alarm up to 19 times, meaningful and meaningless alarm, respectively, accounted for the total number of 3.5 % And 31.1% respectively.

And the incidence of false alarm rate of 65.4%, which, arrhythmia alarm error rate as high as 99.9%, breathing alarm error rate of 86.7%.

Meilun such a one after another figures, warning us: the monitor in our clinical meaningless alarm has indeed become a "common", "wolf" story has occurred, will undoubtedly give us the maintenance of operations Add certain difficulties.

What factors can cause the monitor to be faulty?

Fault alarm factors are as follows:

① alarm parameters of the upper and lower border adjustment is not appropriate, such as the upper limit is set too low, the lower limit is set too high will affect the monitor alarm frequency;

② external disturbances or muscle tremor caused by false positives irregular rhythm;

③ on those who installed the pacemaker patients, we did not set the form of pacing care;

④ electrode parts placed in those parts of the skin redness itching and so on.

Fault or meaningless alarm, how to reduce?

1, replace the electrode pieces every day

Some scholars have pointed out that every day to replace the electrode, you can reduce the alarm by 46%. In our clinical practice, to the patient paste the electrode when the time, we do not have to deal with the patient's skin, we usually point in the patient is also told when the electrode pieces fall to replace. Therefore, the daily replacement of electrode pieces into our handling operations, is also very necessary.

2, the alarm limit reasonable settings

Clinically, the alarm limit of the monitor, neither can be set too wide, can not be set too narrow, and we face the problem is now the international alarm on the limits of the set, there is no consistent specification.

Gross and other heart rate alarm limit from 120 times / min adjusted to 130 times / min, the alarm reduced by 50%.

We also need not the same patient, the same treatment, improve the effectiveness of the monitor alarm!

3, improve the criteria, pay attention to staff training

It is also necessary to properly correct the monitoring rules of the monitor and to expose it and to carry out occasional inspections when necessary, according to the problems existing in the hospital monitoring and alarming.

Together, the hospital should also pay attention to the staff of the monitor alarm "knowledge of the line" in the training, real-time understanding of the use of foreign monitor status, the monitor alarm and the guidelines into the pre-training training, Nurses clinical thinking ability to cultivate, for example: how to set the alarm value, false alarm identification and processing, etc.
