The monitor measures respiration mostly by the electrical impedance method. It mainly picks up the electrical signal caused by the change of respiratory impedance of the human thorax through the two electrodes RA and LL, analyzes and processes it by the machine system, and finally obtains the process of breathing frequency.
No breathing waveform or abnormal breathing waveform, inaccurate measurement. It can be known from the measurement principle of RESP that the breathing signal. Detection is done by ECG electrodes, so it is inseparable from ECG. Specifically, the following four factors should be excluded:
(1) To exclude the interference of the patient's frequent activities and severe coughing, it should be measured in a calm state.
(2) Correctly place the electrodeposition, especially the positions of the RA and LL electrodes should be placed correctly.
(3) Exclude the influence of the quality of the lead wire, the electrode pad itself, and poor con, tact.
(4) The breathing module is faulty and needs to be disassembled for repair or replacement.
