Applying the Cuff (250 SE)
The microphone is positioned so that it lies on the brachial artery, the largest arm artery. The location of
the microphone in the cuff is marked with a red fabric tag.
The ideal location for the microphone is approx. 2 centimetres above the elbow joint on the inside of the
arm, below the biceps. The cuff must be put on so it is tight and cannot shift out of position during the
movement created during the stress test.
The cuff is inflated rapidly at the start of the measurement. The blood pressure and pulse rate are already
roughly measured during pumping and the inflation pressure is determined.
After the systolic pressure value has been attained, the air is released from the cuff at a rate of 3 mmHg
per heartbeat.
This procedure guarantees approximately equal measuring times despite the rising pulse rate during
exertion.
The blood pressure measurement should not exceed a maximum total length of 45 seconds. One minute is
indicated as the shortest measurement interval. A measurement interval of 2 or 3 minutes is preferable in
most cases.
The blood pressure values are shown in the ergometer's graphic display together with the load and pulse
rate graphs.

Positioning of the Patient on the Couch
The advantage of semi-couch ergometry is the patient’s ideal positioning on the ergometer. In a 45
degrees position, the performance corresponds to the performance on a bicycle ergometer. Nevertheless,
the patient is lying in a very relaxed position. This prevents artefacts during blood pressure and ECG
measurement, enabling a better evaluation of the results. For elderly and sick patients, the reclined
position is very safe and comfortable. The 45 degrees position should only be left if resuscitation is
necessary or for heart catheter examination.
The saddle serves for setting the correct distance between the body and the pedals. The headrest’s
purpose is to provide a comfortable position for the head. The paper on the paper roll acts as surface cover
and sweat absorber during the stress test.
