 Patient is comfortably seated
 Patient's legs are uncrossed
 Patient's feet are flat on the floor
 Patient's back and arm are supported
 The middle of the cuff is at the level of the right atrium of the heart
Blood pressure measurements can be affected by the patient's position,
physiological condition, and environmental factors.
Physiological conditions that can affect blood pressure measurements include,
but are not limited to, cardiac arrhythmias, arterial sclerosis, poor perfusion,
diabetes, age, pregnancy, pre-eclampsia, renal diseases, trembling, or
shivering.
Note: It is recommended to notify the patient to relax and not talk during the
measurement.
Note: It is recommended that 5 minutes should elapse before the first reading
is taken.
Operation - NIBP
Root works by noninvasively monitoring the amplitude of cuff pressure
changes during cuff deflation to determine arterial blood pressure. The cuff
pressure is first elevated above the patient systolic blood pressure level. The
cuff will then begin to deflate at a certain rate. The initial rise in the amplitude
of pressure fluctuations during cuff deflation corresponds closely to the
systolic blood pressure. As the cuff is further deflated, the pressure
fluctuations increase in amplitude until a peak is reached which is usually
referred to as the mean arterial pressure (MAP). As cuff deflation continues,
