How to improve the effect of defibrillator monitor

The following points should be achieved when defibrillation operation is performed.

1. Choose synchronous or asynchronous defibrillation according to the patient's indication, and choose energy according to the instruction of instrument operation manual according to different models.Meilun

2 during defibrillation operation, the electrode plate should be fully contacted with the skin and put a certain pressure to ensure good contact.

3 In vitro defibrillation, it is better to use conductive paste in order to make the electrode plate have good contact with the patient's skin (ultrasonic coupling agent and conductive paste have similar properties, but different properties, so we can not use ultrasonic coupling agent instead of conductive paste, so as to avoid bad contact). If salt water is used, gauze should be wrapped on the electrode plate and salt should be prevented. Too much water leads to short circuit; alcohol is strictly prohibited during defibrillation operation, so as not to cause burns to patients.Meilun

4. Remove the conductive paste from the electrodes completely after each use and keep the electrodes clean. Charge the batteries in the machine in time.

How can we quickly determine if the main function of the instrument is normal?

First, check the monitoring function. The lead can be selected at the paddle-shaped electrode, and the sternum electrode plate and the apical electrode plate can be touched with both hands respectively. If the ECG waveform is displayed on the screen, the monitoring function is basically normal.

Two, check defibrillation function can generally use soap as medium, observe discharge spark. The specific operation is: remove the handle from the machine, clamp a piece of soap between the two electrode plates, and then carry out "defibrillation charging". After charging, press the power button at the same time. At this time, the discharge spark can be seen at the electrode plate holding the soap.  The size of the spark is related to the size of the selected energy. When discharging, pay attention to the fact that the body does not touch the electrode plate, nor can the two electrode plates be directly short circuited.Meilun

The above-mentioned method can not replace strict testing, but if the above-mentioned inspection can not pass, the instrument must be repaired. Preventive maintenance is the key to ensure that the instrument is always in good working condition.

What routine maintenance should the equipment users complete?

First, we must conscientiously implement the system of shift handover. Each shift should check whether the power cord is damaged, whether the lead wire and electrode clamp (button) are intact, whether all kinds of accessories are complete, and whether the recording paper is used up (if it is about to be used up, it should be replaced in time and the installation is correct).

Second run a self checking procedure on each shift. Taking AED as an example, a report will be printed after the instrument has passed the self-inspection. If a prompt "Serves Unit" appears, indicating that the instrument has not passed the self-inspection, engineers and technicians should be notified in time for processing.

Third clean the appearance of the instruments once a class. Clean the display screen with soft cloth and clean the appearance with 90% alcohol or neutral soapy water, but the liquid should be prevented from flowing into the machine.

Fourth always pay attention to the system time of the instrument. The system time of various medical instruments used in China should be calibrated according to Beijing time.

The system time is not displayed on the operation panel, but after each defibrillation operation, the instrument will automatically print a record including the operation time, parameter selection and so on according to the system time. This kind of record is an important medical document. If the system time is wrong, it will be embarrassed when it comes to the proof of medical disputes. Therefore, once the system time is found to be wrong, the engineering technicians should be informed immediately.

Fifth, engineers and technicians usually carry out preventive maintenance regularly, including battery performance inspection, defibrillator discharge capacity inspection and electrical safety inspection. When the engineers and technicians carry out preventive maintenance, the medical staff should cooperate with each other and should not miss the inspection because the instrument has been in normal use or is afraid of trouble.

In recent years, with the enhancement of patients'awareness of self-protection, medical units are also actively improving their work to reduce the occurrence of medical errors. One of the measures is to ensure the safety and effectiveness of emergency equipment. Therefore, it is of great significance to strengthen the training of users and strict operation rules so as to make them use and maintain the instruments correctly in order to reduce the risk of clinical first aid.
