Warning
• Patient Hazard •
Do not take blood pressure measurements with a cuff on
patients suffering from sickle cell anemia or where skin lesions
are likely to occur.
The cuff may cause hematomas in patients with severe blood
coagulation disease. In these instances, the user must take a
decision for or against automatic blood pressure measurements.
Caution
• Compromised Measuring Accuracy •
Arrhythmias occurring frequently during a measurement may
compromise the accuracy of the measurement.
In certain cases, a valid measurement will not be possible.
Electromagnetic fields are also capable of impairing the measu-
ring accuracy.
Note
• If the cuff pressure exceeds the maximum value of
300 mmHg during inflation, the inflation procedure will be
aborted and the cuff deflated.
As a redundant safety precaution, the cuff is immediately
deflated when the cuff pressure exceeds 320 mmHg.
You can check the proper functioning of this safety precau-
tion by abruptly bending your arm while the cuff is being
inflated, causing a brief overpressure in the cuff. The cuff
must deflate immediately.
• Measurements that did not yield a valid measurement will
not be repeated during the exercise test.
• If the inflation phase takes longer than 40 seconds or if an
adequate pressure does not build up in the cuff within a
reasonable period of time, the measurement will be aborted
and the cuff deflated.
• If a valid measurement cannot be completed within
120 seconds, the measurement will be aborted and the cuff
deflated.
• If the cuff pressure remains constant for some time, the
measurement will also be aborted and the cuff deflated.

The following patient categories are excluded from using
the device:
• patients feeling discomfort or suffering from dizziness,
nausea or pain.
• patients under the influence of substances that may
impair vigilance (alcohol, drugs, medication).

Contraindications in exercise testing:
• acute myocardial infarction in the previous 4 to 6 days
• unstable angina with rest pain in the previous 48 hours
• uncontrolled heart failure
• acute myocarditis or pericarditis
• acute systemic infection
• deep vein thrombosis as it is likely to shift and cause
pulmonary embolism
• uncontrolled hypertension with systolic blood
pressure > 220 mmHg or diastolic blood pres‑
sure > 120 mmHg
• severe aortic stenosis
• severe hypertrophic obstructive cardiomyopathy
• untreated life‑threatening arrhythmia
• dissecting aneurysm
• recent aortic surgery
• abnormalities during testing include:
− abnormal ST‑segment response (horizontal, planar
or down‑sloping depression of > 1 mm).
− T‑wave elevation of > 1 mm in leads without
Q‑waves.
− T‑wave changes such as inversion and pseudo‑
normalization when an inverted T‑wave becomes
upright are non‑specific changes.

(source: Banerjee A et al., 2012).
Criteria for stopping bicycle based exercise testing include:
ECG criteria
• severe ST depression of > 3 mm
• ST elevation > 1 mm in non‑Q‑wave lead
• frequent ventricular extra systoles
• onset of ventricular tachycardia
• new atrial fibrillation or supraventricular tachycardia
• development of new bundle branch block
• progression of heart block to second or third degree
• cardiac arrest
