I am looking over various sources of material while studing for the NREMT and I found this question.
You should use a new oxygen cylinder when the old one reaches _______ psi.
200
500
50
350
I found this question on the princeton hall site ( http://wps.prenhall.com/chet_limmer_emergencycare_10/0,9043,1281755-,00.html )
my book AAOS 9th ed states most EMS services consider a tank less than 500 to 1000 psi too low. So I answered 500. I got it wrong according to Princton Hall, without getting into the real world answer which is the correct answer for the test.
I look forward to your assistance and opinions.
