NBP Monitoring
6. Non-Invasive Blood Pressure
Monitoring
6.1. Overview of NBP Monitoring
The PPM3 uses an oscillometric method to measure the patient’s blood pressure.
In this method, a blood pressure cuff is quickly inflated above the patient’s
systolic pressure, and then the cuff pressure is slowly released in a series of steps.
At each cuff pressure step, oscillations in the cuff pressure are measured. These
oscillations are made by the underlying blood vessels which are pushing on the
cuff during the cardiac cycle. From these oscillations, the patient’s blood pressure
can be derived.
The Non-Invasive Blood Pressure (NBP) monitoring capabilities of the
Nightingale PPM3 include:
•
Calculating the patient's systolic, mean, and diastolic blood pressures
•
Spot check and automatic measurement intervals
6.2. Getting Started with NBP on the PPM3
To begin NBP monitoring, use the following procedure:
1. Attach the NBP cuff to the patient.
Please refer to the Accessories chapter for a list of Zoe Medical approved
NBP cuffs for use with the Nightingale PPM3. In order to get good
quality NBP measurements, you need to use a cuff that is the appropriate
size for the patient. Measure the circumference of the patient's limb and
compare this to the size marked on the NBP cuff.
The patient should be sitting or lying down, and the patient's arm or leg
should be relaxed, extended, and resting on a stationary support.
Wrap the deflated cuff snugly around the patient's arm or leg according to
current AHA guidelines, taking care not to restrict blood circulation.
