Answer to Question 1

ANS: B
Transtracheal oxygen catheters, reservoir cannulas, and pulse-demand oxygen-delivery systems are recent developments that have significantly improved the delivery of oxygen therapy, espe-cially with regard to conserving oxygen supplies during long-term oxygen therapy.

Answer to Question 2

ANS: B
The demand valve connects directly to the oxygen source (50 psig), therefore replacing the flowmeter that is used with continuous-flow cannulas. Note that demand systems can function as pulsed or continuous-flow sources of oxygen. Settings allow the operator to select the equivalent of 1 to 5 L/min of oxygen flow from a conventional flowmeter.
