5.2.3 Safety Information for Non-Invasive Blood Pressure Measurement
Contraindications:
– sickle cell anemia
– skin lesions
The following factors may have an effect on blood pressure
measurements:
– cardiac rhythm disturbances (arrhythmias)
– arteriosclerosis
– low perfusion
– diabetes
– age
– pregnancy
– pre-eclampsia
– renal diseases
– patient motion, trembling, shivering
– environment (extreme temperatures, humidity, altitude
(m above sea level) and electromagnetic fields)
Frequent measurements can impair perfusion and may
considerably harm the patient.
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 do 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 sec
onds, the measurement will be aborted and the cuff deflated.
• If the cuff pressure remains constant for some time, the mea
surement will also be aborted and the cuff deflated.
5.2.4 Cuff Size
The cuff is only intended for application on the upper arm
(left/right).
The maximum arm circumference is indicated on the cuff.
Warning
Do not apply the cuff on a lesion because this
may entail further damage.
