1. Measuring instrument incl flow meter ON D750 The Measuring instrument provides an easy way to measure and detect if there is something wrong with ECG function of Decapus Ill If the resistance deviates much from the default value for a patient lead this may indicate a fault condition With the flow meter it is easy to measure the system s airflow to find if any leakage has arisen which affects the vacuum Salt bridges can occur both in the patient cable and signal module e The resistance between the shield and the patient lead may indicate the existence of salt bridges between the system s shield and the chosen lead Keep in mind that the chance of detecting salt bridges is best if the system is tested when a problem has just occurred If moisture has time to dry off the possibility of detecting salt bridges is lowered 1 Resistance measurement a Connect the signal module A without Quickels electrode to respective electrode lead position Plug the recorder cable into the D SUB of the measuring instrument Decapus lll does not need to be connected to the mains b Set the multimeter to Q and connect the multimeter s test leads in B ECG End and C Patient Cable End c Turn the knob E to the selected patient lead and record the value If the value of the resistance of the lead deviates much from the default value this lead has to be investigated in more detail see section Troubleshooting Resistance of the in2. 31 O O Interference on the ECG trace First thing to do when encountering a disturbed ECG signal is to determine wether the disturbed ECG signal arises from the Decapus Ill or the external ECG printer and not a bad electrical contact to between the electrode and patient With normal troubleshooting refers to 1 Check the Quickels electrode electrolyte and placement of the Quickels electrodes 2 Check by using the printer switch which channel is incorrect ECG measurement can be affected by many factors in the measuring environment It could for example be any of these factors e The static electricity in the room is high e Mains cables 50 60 Hz in the patient environment or in close proximity to the recorder cable e Mains cables in a wall near the patient 50 60 Hz e It is also assumed that the six initial assessments described in the introduction of section Troubleshooting guide has been completed IRREGULAR BASE LINE Typical curve with irregular base line is probably caused by fluctuating vacuum level This may in turn depend on leakage in the vacuum system The stabilization of the skin electrode interface may affect the base line This might occur due to excessive movement of the patient which may cause leakage of the electrodes The base line normally stabilizes within a few seconds but stabilization in some cases may take longer e g if the skin is tight tibia Attach if possible the electrode
