To apply the cuff
Before applying the cuff to the patient, read and
understand the manufacturer’s warnings in the
Instructions for Use for the cuff.
1
Place the cuff 2 to 5 cm (1 to 2 inches) above
the elbow (or around the middle of the thigh).
Place the cuff label "this side to patient" against
the skin.
2
Place the artery marker (B) over the artery
pointing to the hand or the foot. Place the cuff
label ’index’ (A) so that it falls within the range
labels (C) to ensure the correct fit. If the cuff
does not fall within the indicated range, select a
cuff that better accommodates the limb
circumference.
3
Wrap the deflated cuff snug around the limb
without impeding blood flow. Make sure there is
a finger’s width of space between the cuff and
the upper arm or thigh before fastening it.
Non-invasive blood pressure display
On the Cockpit, the non-invasive blood pressure
display consists of a parameter field.
When a measurement is in progress, the
background of the lower part of the parameter field
turns white.
During low systolic or diastolic pulse amplitudes or
significant motion artifacts, the parameter field may
only display a mean value. If the M540 is in venous-
stasis mode, the cuff pressure and the label
Venous stasis
appears in the non-invasive blood
pressure parameter field .
If you cannot apply the cuff at heart level, adjust the
displayed systolic and diastolic non-invasive blood
pressure values as follows: add 8 mmHg (1.1 kPa)
for each 10 cm (4 inches) above the heart; subtract
8 mmHg (1.1 kPa) – for each 10 cm (4 inches)
below the heart.
Non-invasive blood pressure
parameter
fields
Parameter fields report parameter values and
indicate the alarm status of parameters. Parameter
fields can also report technical conditions such as
disconnected sensors and so on. For detailed
information regarding the content of parameter
fields for each parameter, see the chapter
"Troubleshooting" on page 509.
The appearance of non-invasive blood pressure
parameter fields also depends on the selected non-
invasive blood pressure mode.
NOTE
Blood pressure measurements can be affected by
arrhythmias (for example, atrial and premature
ventricular contraction), atrial fibrillation, low
perfusion, diabetes, renal diseases, trembling and
shivering. In the presence of implausible
measurement values check for the above-
mentioned reasons and repeat the measurement.
If possible, wait for a few minutes before
performing another measurement at the same
measuring site.
NOTE
The following diagram shows a typical parameter
field layout. This layout may change when
additional parameters are put on display. For
more information, see "Parameter fields" on
page 62.
