2-1. Preparing for Measurement
4.
Attach the PCG sensor.
• Normally the PCG sensor is placed at the left edge of
the sternum in the fourth intercostal space (4). If the
second heart sound is not clear, measurement can
also be performed with the sensor in the middle of the
third intercostal space (5), or near the right edge of the
sternum in the second intercostal space (6).
• While viewing the display, find the position where the
PCG sensor can accurately measure the 2nd sound
("PCG: OK" is displayed).
Using the PCG Sensor Weight
■
Please use the PCG sensor weight when "PCG:OK" is not on the display even after the sensor is
placed on the appropriate position.
• Thick fat or muscle that attenuates heart sounds.
• Excessive body hair does not allow the PCG sensor to fully contact the skin.
• Due to contour, the perceptive part of the sensor possibly does not contact appropriately with
body surface.
• Because a patient does not keep in a horizontal position, the sensor may be declined, which
makes the perceptive part fail to adhere to body surface.
These problems can be resolved by using the PCG sensor weight.
1.
Place the PCG sensor weight (1) on top of the PCG
sensor (2).
The PCG sensor weight can be placed over clothing.
2.
Make sure that the display shows "PCG: OK".
Notes:
• Do not use a weight that has a hole or is torn.
• If the filling leaks out of the weight, clean it up promptly.
• Be careful not to damage the surface of the weight with a ballpoint pen or other sharp pointed
object.
• If sweat or water gets on the weight, wipe it off immediately.
• Do not wash with water.
