- CPAP is the acronym for "Continuous Positive Airway Pressure". A CPAP device is used in respiratory therapy. Some ambulances carry a CPAP device. The pressure unit used in CPAP devices is "cm H2O". A typical pressure setting on a CPAP device may be 9 cm H2O. Blood pressure is commonly measured in units of mm Hg (or millimeters mercury). Which of the following statements is true regarding the pressure of 1 cm H2O ? Question 17 options: A) 1 in H2O has a lesser pressure than 1 cm H2O. B) 1 in H2O has a greater pressure than 1 cm H2O. C) 1 mm Hg has a lesser pressure than 1 cm H2O. D) None of the above answer choices are correct.For $350.0 you can purchase a cylinder of helium gas on line, with a volume of 2.373 cubic feet and a pressure of 2215 psi at 70.0 degrees fahrenheit( 21.1 degrees celsius).
