Do you know the % of accuracy allowed regarding the monitors MAP equation? For instance, if I have 87/72 my Philips monitor will give me 76 but if I use my calculator, it is 77. So I can’t seem to find the allowable % of accuracy. I am asking for a nurse regarding a neonatal monitor so I am always looking for as accurate as possible.

If you try the formula on the numbers displayed by the monitor they may not add up. In fact most of the monitors estimate BP based on the so called oscillometric method. When you measure BP using manual sphigmomanometer and open the valve to gradually deflate cuff the needle of the manometer will go smoothly down until you hear the first Korotkoff sound. At this point the needle will go down but oscillating (jerking) with each sound. As the needle goes down the amplitude of this tiny oscillations increases then reaches the maximum, decreases and disappears. The cuff pressure at which the amplitude of this oscillations is maximum is the MAP. It is difficult–although not impossible–for us to by looking at the manometer needle, determin when the amplitude of the oscillations is maximum. For machine it is relatively easy task. BP monitors first calculate MAP and then based on amplitudes before MAP determine SBP and based on amplitudes after MAP calculate DBP. It is fun to try to figure MAP using manual sphigmomanometer.

I want to know how is the normal blood pressure (magical figure of 120/80) is arrived, by which method?

Heart monitors calculate MAP using the same formula and adding the heart rate divided by 10.
Because heart rate does play a role in the determination of MAP.
When using invasive monitoring CVP is used to calculate MAP, by adding the divided heart rate you can get closer to a true MAP.

The main thing to understand is that without central monitoring the calculated MAP is a close proximity, not 100% accurate.

@Bimu, thank you for your input about MAP calculation formula. Please note that this explanation on how to calculate mean aterial pressure is only explaining how the MAP formula was derived at

Thank you Dr Awais for your compliments. I definately will dig into the monitors but I bet they compute the Systolic Blood pressure and diastolic blood pressure and they calculate the MAP using mean aterial pressure formula we all know about. Not hard to do at all programmatically using a software

@July, my explanation kind of decodes the formula or MAP and explains how that formula was formulated. I hope you found it helpful

With the numbers above explained and how MAP is calculated, it is not so evidence based practice (EBP) to dictate a mean aterial pressure based on age. So many factors come to play and that is why we only deal with a minimum mean aterial pressure of 60mm/Hg.

so now that we have the MAP …what is the recommended range for male in 70s ?

And it gives you the same answer. For example: (60×2) + 120 / 3 = 240 / 3 = 80mmHg. The explanation to it is the same as one given above.

—————————-
3
= mean arterial pressure
You did have good answer behind the formula, sometimes we as nurses are told to learn a formula, but do not receive the theory behind it. I makes so much sense to learn both at once.

The next question would be, does a MAP of 80 have the same indications for a cat as it does for a human?

MAP is calculated the same way in human and cat. In a cat with heart rate of 160 and pressure of 120/60 and a human with heart rate of 70 and pressure of 120/60, do they have the same MAP?
