Pulsewave Blood Pressure Measurement
Working Principle
A simple way to understand the Principle of PulseWave BP Monitor

It imitates mercury BP Monitor.

But it's better than mercury BP Monitor.

Because it has 2 airbags with 2 tubes and 2 sensors.

Upper airbag functions as pump bulb ,lower airbag functions as the mercury column to detect pulse wave.

The results come from physics and maths algorithm, not by human judgement via hearing and vision.

How to get the Systolic (SBP) ?

H1 stands for the 1st pulsewave amplitude

H2 stands for the 2nd pulsewave amplitude

Pss1 stands for the airbag pressure data of H1

Pss2 stands for the airbag pressure data of H2

Pss0 stands for the airbag pressure data when pulsewave amplitude is 0.

So,we can get below equals:

(Pss1-Pss0)/H1=(Pss2-Pss0)/H2

Therefore,Pss0 is the highest pressure (SBP)

When start to measure with the pulsewave cuff, the upper airbag gets enough pressure to block the blood flow of the brachial artery, then it gradually released the pressure of upper airbag until the moment that the blood flow rushes into vessel (we call this moment as Pss0),at this moment, the pulse will generate an intensity wave,this wave compared with the airbag pressure wave,there will be a LINER DATA,we call Pss0 as the highest pressure,that is SYSTOLIC PRESSURE (SBP).

How to get the Diastolic (DBP) ?

When blood rushes into vessel,with the pressure released from the upper airbag, there is a time delay for blood flow from heart to brachial artery , and the moment when this time delay gradually approaches zero,it means the blood can flow freely without any external pressure,just flow by the heart beats pressure,this moment stands for the lowest blood pressure (DBP),we call it Psz0.

Psz1 & Psz2 & Psz3 & Psz4 : Separately stands for lower airbag pressure data (which also means the pulsewave pressure data) at each SBP points.

T1 & T2 & T3 & T4 : Separately stands for the TIME DELAY of pulsewave according to Psz1/2/3/4.

PszA & PszB : Separately stands for lower airbag pressure data when upper airbag pressure data is smaller than DBP data.

TA & TB : Separately stands for the matching time dalay.

Psz0 stands for upper airbag pressure data at DBP point

T0 stands for the matching pulsewave time delay on this DBP point.

So,we'll get below equals:

(TA+TB)/2=T0

(Psz1-Psz0)/(T1-T0)= (Psz2-Psz0)/(T2-T0)= (Psz3-Psz0)/(T3-T0)= (Psz4-Psz0)/(T4-T0)

Therefore, Psz0 is the lowest pressure (DBP)00

Accuracy Testing

1.By using a Three-way-pipe, connect the pressure tube of Pulsewave BP Monitor and mercury sphygmomanometer, then connected to the pressure port .

2. Put the stethoscope under the edge of cuff, keep a distance of 2-3 cm from chelidon

3.When measuring, use a cloth cover the screen, read the value from the mercury sphygmomanometer, then compare the results from two BP Monitors.

Conclusion

The results are consistent

The Pulsewave BP Monitor is definitely accurate and reliable

Instructions for getting an Accurate Measurement Result

Keep calm/peaceful for 3~5 minutes before measurement

Keep silent during measurement,no talking

Take off your backpack

Take off your thick coat

Do NOT roll your sleeve to upper arm

Keep the distance between testing table and chair at 25~30cm

Keep elbow pressing the blue button

Do Not shake legs
