Patient I/O (Currently not supported by the LOGIQ™ 9)
The Patient I/O is mounted inside the Backend Processor’s cabinet with its connector panel available
on the front of the scanner.
The Patient IO contains the electronics for ECG, phono and two analog inputs. One of the inputs has
programmable gain. The module extracts respiration from ECG. The electronics also contains a
pacemaker detector. The four inputs are separately isolated because of safety requirements.
Inputs
•
Phono (from a phono heart microphone)
•
ECG / Respiration
•
AUX1
•
AUX2 (Pulse/Pressure)
These signals are optically isolated from the rest of the system.
Outputs
Serial Trace Data via Internal I/O to the SPD Board.
