If a patient\'s blood pressure is 135 over 55 mmHg, what is it in atmospheres (atm)?

Question

anonymous · Answer

Yes, I tried dividing 55 mm Hg / 760 mm Hg but I got the wrong answer? And when I tried 760/55 I got the wrong answer as well :( @Rushwr

I got 0.003 and it was still wrong! 😫

135 over 55 mmHg are the values for the high and low pressure or systolic and diastolic pressure respectively. They represent two different values of blood pressure in an patient. 135 mmHg ∗1 atm /760 mmHg = High atm 55 mmHg ∗1 atm /760 mmHg = Low atm http://www.cdc.gov/bloodpressure/measure.htm Blood pressure is measured using two numbers. The first number, called systolic blood pressure, measures the pressure in your blood vessels when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your blood vessels when your heart rests between beats. If the measurement reads 120 systolic and 80 diastolic, you would say "120 over 80" or write "120/80 mmHg."

By the formula 55/760 I get 0.07, but that answer is wrong? @Cuanchi @Rushwr

anonymous · Answer

3.2 x 10^-3 shows incorrect. I have already 0.18 atm. I need 0.18 atm over _____ atm. Which I keep missing :(

should i just give up and view solution? XD

cuanchi · Answer

did you try 0.072 with 2 significant figures> It is the number of significant figures important in your result?

cuanchi · Answer

135 over 55 mmHg
0.178 over 0.072 atm ?

usually the significant figures don't matter on the website, but I guess the extra 2 did the trick! Thanks! :)
