Patient Instructions - Spacelabs 90207 Operation Manual

Correlating with Manual Readings
The monitor bleeds pressure in discrete steps (not continuously) using the oscillometric method of
blood pressure determination. If manual pressure readings are taken simultaneously with the
monitor readings, interpolation is required to accurately correlate monitor systolic and diastolic
pressure values with the manual auscultatory pressures.
• For systole, record the first pressure at which a Korotkoff sound is heard. Actual systolic
pressure is somewhere between the pressure when the sound is heard and the previous
(higher) pressure where no sound was heard. The interval of uncertainty can be reduced by half
by adding one half of the bleed step size (4 mmHg) to the manual systolic pressure.
• For diastole, record the cuff pressure at which the last Korotkoff sound was heard. Actual
diastolic pressure is somewhere between that pressure and the next lower pressure. Thus, you
must subtract one half of the bleed step size (4 mmHg) from the manual diastolic pressure.

Patient Instructions

If the cuff becomes uncomfortable during a reading, make certain the patient knows how to
terminate the readings by pressing the STOP key on the front of the monitor.
If the cuff slips out of place, make certain the patient understands correct repositioning of the cuff for
successful readings. If the cuff is not properly positioned, event codes may appear on the monitor.
• The patient should make every effort to keep the monitor dry. However, there is
!
no hazard if the monitor does get wet. If this occurs, turn the monitor off and return
it to Spacelabs Medical for service.
