Chapter vii. Critical diseases
How to choose the conductance of cardiac monitoring?
There are usually three guides and five guides. Three conductance: a negative (red) : the lower margin of the right clavicle; (yellow) : the fourth rib in the left axillary line; Ground electrode (black) : the blade is right on the right. Five conductance: (RA) on the right (RA) : the first rib of the middle line of the right margin of the sternum. On the left (LA) : the first rib in the left margin of the sternum; Lower right (RL) : right subclavicular level of xiphoid; Lower left (LL) : lower left clavicular level (C) : left margin 4.
What are the precautions for applying cardio monitoring?
After entering the ICU, the regular electrocardiogram (ecg) was recorded as the basis for the comprehensive analysis of the changes in heart potential. When placing the monitor and conducting electrodes, it is necessary to set aside and expose a certain area of the heart in order to prevent the monitoring and removal of the electrode. The electrodes should be cleaned before the electrodes are placed, so as not to affect the electrical monitoring effect. The best monitoring guides should be selected to obtain a clear ecg waveform. Pay attention to avoid the false difference caused by interference.
What are the main points of observation of electrocardiogram?
Observe whether the ecg has P waves, and whether P waves are present in the form, height, and width. Observe whether the QRS waveform is normal and has no leakage. Observe that the ST segment is either elevated or decreased, and if there is an abnormality found in the bed by the bedside electrocardiogram (ecg) to clarify the occurrence of myocardial ischemia or myocardial infarction (myocardial infarction). See if T waves are normal. Look for abnormal waveforms. In order to set the alarm range according to the condition of the condition, the reason should be clear and timely.
