Physiological Unit 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 2.8 Physio Unit Panel (ECG) for details.
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.
WARNING:
Do not use the physiological traces for diagnosis and monitoring.
To avoid electric shock, the following checks shall be performed prior to an
operation:
The ECG electrode cable must not be cracked, frayed or show any signs of
damage or strain.
The ECG electrode cable must be correctly connected.
You must use the ECG leads provided with the physiological unit
module.
Failure to do so may result in electric shock.
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.
Do not place the ECG electrodes directly in contact the patient’s heart;
otherwise it may lead to stop of the patient’s heartbeat.
Do not apply the ECG electrodes if the voltage exceeds 15 volts. This could
produce an electric shock.
Do not use this system when any digital device such as a high-frequency
electrotome, high-frequency therapeutic device or defibrillator is applied
already.
Conductive parts of electrodes and associated connectors for ECG should
not contact other conductive parts including earth/grounding.
Do not use PCG with the defibrillator or contact the PCG with patient during
defibrillation.
Frequent trampling or squeezing on the cables may result in cable
break-down or fracture.
Display effect of respiratory curve depends on the patient breathing status.
While a very slow or smooth breathing may lead to an inapparent
respiratory curve, breathing in a large amplitude may cause an incomplete
display of the respiratory curve. Display effect is linked to the connected
parts of the body. Generally, signals by connecting to limbs are stronger
than by connecting to the chest.
