Question

If a patient\'s blood pressure is 145 over 85 mmHg, what is it in atmospheres (atm)?

Answer 1

in 1(atm) the patients blood is 760 mmHg

Answer 2

Answer: 0.190 over 0.11 atmosphere

Step-by-step explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..

All these units of pressure are inter convertible.

We are given:

Pressure of the gas = 145 mmHg over 85 mm Hg

Converting this unit of pressure into 'atm' by using conversion factor:

`760mmHg=1atm`

`145mmHg=(1)/(760)* 145=0.190atm`

`85mmHg=(1)/(760)* 85=0.11atm`

Thus there will be 0.190 atm in 145 mmHg and 0.11 atm in 85 mm Hg.

The patient's blood pressure is 0.190 over 0.11 atmosphere.
