What is the physical meaning of pulse rate and blood pressure, from a turbo machinery point of view?
Our hearts are peristaltic pumps, which has a periodic compression and expansion. The head developed can be taken as blood pressure.
There are situation when the blood pressure is normal while the pulse rate is high. What is the physical meaning of this?
Does it mean?

high pulse rate + low pressure means low pumping efficiency of the heart. this can be caused by:

Another mechanism. High pulse rate and low pressure also occurs when there isn't enough blood (hypovolemia). Blood loss often causes hypovolemia.

thanks, answer edited to include low blood volume and fibrillation

What is wrong with the turbo machinery? What size is it? Which manufacturer?

@SolarMike My BP is normal(110/65) but pulse is always around 90+, even at rest. As an engineer had to understand the pump issue!

Plus "fibrillation", where the various parts of the heart are not correctly synchronised with each other and the resultant overall pumping effect is small. Blood vessel blockage (or more realistically, partial blockage and/or stiffening of the artery walls) is more likely to cause high blood pressure.
