For stability and measurement accuracy, instruct the patient to stand in the middle of the scale and
not to move while the scale collects the patient's weight. Stepping or standing on the edge may cause
the scale to tip and possibly result in personal injury.
Collecting blood pressure
Proper cuff size and placement are essential to the accuracy of the blood pressure reading. Every cuff
has an arm size range (in centimeters) printed on the outside label. The smallest and largest points in the
range are determined as follows:
•
The smallest size in the range is the point where the tab can no longer be pulled through the
ring. If the cuff is still loose, use the next smaller size cuff.
•
For the largest size in the range, the ring should fall in the natural break of the cuff. The natural
break is the seam where the two Velcro patches meet. If the arm is larger than this, use the
next larger cuff size.
The blood pressure cuff may be used on either the right or left arm, but the patient should use the same
arm consistently. Show the patient where to rest their arm so that it is at heart level in order to obtain
the most accurate reading. The BP Cuff should be placed on the opposite arm of the Oximeter.
The position of the patient's arm can significantly affect the readings. In general, the arm should rest
supported below the level of the heart. A consistent position should be used for each reading to
increase the accuracy of the data.
While taking blood pressure, the monitor displays the real-time cuff inflation pressure in the Systolic
display. When the reading is complete, the monitor displays systolic and diastolic results.
Safety notes
Any blood pressure measurement can be affected by the position of the patient, movement, talking,
physiological condition, and other factors.
Make sure that the BP hoses are not kinked, compressed, or restricted.
Check to ensure that the operation of the equipment does not result in the prolonged impairment of
the circulation of the patient. Point out that the patient can stop the inflation at any time by pressing
the red STOP key. To restart inflation, press the green START key.
Inflation pressure
The Genesis DM monitor has a preset default inflation pressure of 175 mmHg. However, it only uses
this setting once because the Genesis DM monitor saves the last BP reading in memory. The next
inflation pressure is 35 mmHg above the last saved systolic.
If the patient's blood pressure is higher than the inflation pressure, the Genesis DM monitor increases
the pressure by 35 mmHg, re-inflates, and takes a new blood pressure reading. If the monitor cannot
obtain a blood pressure after a total of three attempts, the monitor displays an error.
