  a. Variable-orifice, constant-pressure flow-meter device
  b. Fixed-orifice, constant-pressure flowmeter device
  c. Variable-orifice, variable-pressure flow-meter device
  d. Fixed-orifice, variable-pressure flowmeter device

Question 2

You are preparing to conduct a complex transport of a patient receiving O2, and you expect to have to alter O2 flows during the transport. Which of the following devices would best meet your needs?
 
  a. Uncompensated Thorpe tube
  b. Flow restrictor

Answer to Question 1

ANS: A
Compared with the flow restrictor and the Bourdon gauge, the Thorpe tube functions as a varia-ble-orifice, constant-pressure flowmeter device, so increasing the size of the orifice increases the gas flow.

Answer to Question 2

ANS: D
The Bourdon gauge is the best choice when a flowmeter cannot be maintained in an upright posi-tion.
