Measuring blood pressure
WARNING!
Hazard to patient
► Do not use luer lock adapter on the blood pressure measurement
tubes. The use of luer lock adapters can lead to accidental connec-
tion of the blood pressure tubes to intravenous lines and thus lead
to an infusion of air into the bloodstream of the patient.
► The decision to use this device with pregnant or preclamptic
patients is the responsibility of the user.
► The device has no alarm function. Never leave the patient
unobserved during a measurement.
► Frequent measurements may lead to perfusion disorders and
consequently to severe harm to the patient.
► Route the compressed air tube so that it cannot kink. A kinked com-
pressed air tube leads to sustained cuff pressure. This may lead to
perfusion disorders and consequently to severe harm to the patient.
► Do not place the blood pressure cuff over open wounds. This may
lead to further harm to the patient.
► Do not apply any external pressure onto the blood pressure
measurement tubes or onto the blood pressure cuff.
► For patients with moderate to severe cardiac arrhythmias, inaccu-
rate measurements may result with the blood pressure measure-
ment.
► The following factors may affect the measurement result:
– Measuring location (e.g. altitude)
– Patient position (standing, sitting, lying)
– Physiological state of the patient (e.g. exertion, movement,
shaking, shivering)
– Patient's age
– Arteriosclerosis
– Poor perfusion
– Diabetes
– Kidney disease
► If the measurements seem implausible, check and evaluate the vital
signs of the patient using alternative means. Then check the mea-
surement function of the device with the help of the section
"Troubleshooting".
WARNING!
Patient hazard, incorrect measurement
► Do not place the blood pressure cuff on the arm on the side on
which a mastectomy has been performed.
► Apply the blood pressure cuffs so that the blood circulation of the
patient is not compromised.
► Do not apply the blood pressure cuffs on spots that have weak
circulation or on extremities on which intravenous routes lie.
► High cuff pressures may be unpleasant for sensitive patients. Keep
the patient’s general condition under observation during the
measurement.
