Medical monitor can monitor various body physiological parameters, generally can be divided into basic measurement parameters and measurement parameter is optional.
Basic measurement parameters including ECG (ECG), blood oxygen saturation (SPO2), noninvasive blood pressure (NIBP), heart rate (HR), respiratory (RESP), etc.;
Optional parameters including blood pressure (IBP), breathing at the end of the carbon dioxide (ETCO2), temperature (Temp), cardiac output (co), blood analysis, etc.It can be said that the monitor is an essential tool for monitoring patients, clinical its overall performance, high reliability, substantial low failure rate.
Most frequently substantive fault is caused by improper operation or the use of non-standard, maintenance process will now be part of the common phenomenon and solutions.Ecg monitor to the clinical work has brought a lot of convenience, but it's really so easy to learn?We monitor manufacturer of ecg monitor now four most commonly used to talk about.
The monitor
1. The blood oxygen
There are often patients "very low blood oxygen" to deal with.According to the principle of measurement of the monitor, in patients with peripheral circulation, nail polish, and poor local skin hygiene reason, all can affect the monitor's judgment.If the patient's blood oxygen value is very low, should observe patients condition, especially the local situation.Conditional should be observed when the measured curve, the curve of the very rules have reference value.
2. Breathing
This is one of the most "unreliable" index, influence factors, in general I will combine the patient's breathing.In general, the indicators can be basically "ignore".
3. The heart rate
Personally think that this is the "most useful" monitoring indicators.A barometer of the heart rate is a critical degree of diseases, in addition to the judgment of the serious diseases such as myocardial infarction, arrhythmia, is entirely a matter of heart rate waveform.
4. The heart rate of waveform "trouble" : the mechanism of ecg monitor is different, generally is the number of QRS wave counts for a period of time, then the heart rate is calculated.If there is a premature beat patients, the display of monitor data will change frequently.Sometimes, because of the high lead or T wave, pointed, QRS and T wave height can be very close, the instrument will be "wrong" to them all as heart rate, heart rate can double right now, cause unnecessary "panic".
In addition, the waveform of ecg monitoring is lead by simulation, and electrocardiogram conventional waveform and different (ecg limbs to connect, general monitor are connected on the chest).So, see on the monitor such as st-elevation waveform may not have any problem.
Sum up 3 points, easy to master ecg monitoring
1. Study the instructions, only to "know" of the medical monitoring equipment, will you be able to function;
2. Strictly regulate the operation, to avoid man-made causes and determine the measurement error;
3. The most important thing is: monitor the abnormal index, is the best way to observe the patient's condition immediately, rather than from far away, the instrument under the doctor's advice.We are disease treatment, observation is the patient.Instruments to help us diagnose, don't "be" diagnostic instrument.
