8. In addition to the acquisition of the QRS waveform complex the ECG input and subsequent signal processing computing circuitry perform a number of other functions e They detect a lead off condition if one of the electrode connections is disrupted They detect the presence of pacemaker signals within the QRS waveform complex of the ECG e They generate a synchronization pulse for external use with defibrillators The Defib Sync Pulse output is available at a connector in the rear panel The patient s respiration is detected by using two of the three leads of the ECG electrodes and cable A low level excitation signal is applied to these leads and the variation of the thoracic impedance caused by the breathing is sensed and processed for display and measurement Training 11 9 Theory of Operation and System Architecture NBP Processing SpO Processing CO Processing Temperature Processing 11 10 Training The NBP processing uses an oscillometric technique to provide needed measurements at selected intervals This technique uses an inflatable sphygmomanometer cuff similar to those used by clinicians in routine measurements A motorized pump inflates the cuff to approximately 180 mmHg initially at which point the pressure effectively stops the flow of blood Then under monitor control the pressure in the cuff is gradually reduced while a pressure transducer detects the air pressure and transmits the parameter signal
