Correlating With Manual Readings - Spacelabs 90207 Operation Manual

8. Show the patient how to enter information in the Patient Diary. Make sure the patient knows
what to do if the cuff becomes very uncomfortable during a measurement, if it slips out of
place, or if event codes are displayed on the monitor screen (refer to Patient Instructions ).
Also, ensure that the patient knows how to care for the monitor.
9. When you are satisfi ed that the monitor is operating properly, the remaining measurements
in the Offi ce Check mode may be canceled. Refer to Offi ce Check Mode.
Using Cuff Support
Note:
Keeping the blood pressure cuff in place is very important both for patient comfort and for the
accuracy of the readings. This becomes particularly challenging when the arm has considerable
taper, as is often the case with obese patients.
1. Put the large loop of the support around the opposite arm. Once the cuff is successfully ap-
plied to the patient, adjust the length so that the junction of the straps fi ts well back on the
shoulder towards the neck.
2. Fasten the rear short strap to the rear of the armpit. Be careful to clip to the material only and
not to the bladder.
3. Fasten the front strap to the top layer of the cuff material at the location where the hose exits
the cuff. Adjust the length of these straps to apply a minor amount of tension to hold the cuff
in the correct position.

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 fi rst 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 pres-
sure.
• 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.
The interval of uncertainty can be reduced by half by subtracting one half of the bleed
step size (4 mmHg) from the manual diastolic pressure.
