Physiological Signal 7-1 
7  Physiological Signal 
The physiological unit signal waveform is used for checking ultrasound image in ultrasound exam 
(cardiac exam mainly).     
The system provides the physiological unit input panel, on which ECG and other signals can be 
input. See Chapter 2.9 Physio Panel (ECG). 
  The system is equipped with physiological unit signal module. Tap [Physio] to enable the 
function. 
  The image area shows ECG curves.   
  Support ECG and external ECG; 
Only one port is on the ECG module, which transfers to ECG source via DC-IN. 
1.  DO  NOT  use  the  physiological  traces  for  diagnosis  and 
monitoring. 
2.  To  avoid  electric  shock,  the  following  checks  shall  be 
performed prior to an operation: 
  The ECG electrode cable shall not be cracked, frayed or 
show any signs of damage or strain. 
  The ECG electrode cable shall be correctly connected. 
  You should use the ECG leads provided with the 
physiological module. Otherwise it may result in electric 
shock. 
3.  The  ECG  electrode  cable  must  be  connected  to  the  system 
first. Only after the cable is connected to the system, can the 
patient be connected to the ECG electrodes. Failure to follow 
these instructions may subject the patient to electric shock. 
4.  DO  NOT  place  the  ECG  electrodes  directly  in  contact  the 
patient’s  heart;  otherwise  it  may  lead  to  stop  of  the  patient’s 
heartbeat. 
5.  DO  NOT  apply  the  ECG  electrodes  if  the  voltage  exceeds  15 
volts. This could produce an electric shock. 
6.  Before  using  high  frequency  electric  surgical  unit,  high 
frequency  therapeutic  equipment  or  defibrillator,  be  sure  to 
remove the ECG electrode from the patient, in order to prevent 
electric shock. 
7.  Conductive parts of electrodes and associated connectors for 
ECG  should  not  contact  other  conductive  parts  including 
earth/grounding. 
8.  Frequent trampling or squeezing on the  cables may result in 
cable break-down or fracture.
