 All gas cylinders are chained to the wall.
 All primary oxygen gauges read pressure.
 All secondary oxygen gauges read 50 to 55 PSIG
 All nitrous oxide gauges read O.
D. Test for crossed gas lines by connecting an indexed gas hose on each outlet station in each area
connected to the system and:
 Verifying oxygen gas flow at each oxygen outlet station using an oxygen hose.
 Verifying NO nitrous oxide gas flow at each nitrous oxide outlet station using a nitrous
oxide hose.
E. CLOSE all oxygen cylinder post valves. OPEN only the nitrous oxide cylinder post valves with
regulators connected to the manifold.
F. Exhaust all oxygen gas from the entire manifold and pipeline system by sequentially connecting
an indexed oxygen gas hose to each oxygen outlet station.
CAUTION
Always hold the free end of the hose or hose whip may result in an injury.
G. Verify the following:
 All primary nitrous oxide gauges read pressure.
 All secondary nitrous oxide gauges read 50 to 55 PSIG
 All oxygen gauges read O.
H. Test for crossed gas lines by connecting an indexed gas hose on EACH outlet station in EACH
area connected to the system and:
 Verifying NO oxygen gas flow at EACH oxygen outlet station using an oxygen hose.
 Verifying nitrous oxide gas flow at EACH nitrous oxide outlet station using a nitrous oxide
hose.
CAUTION
Always hold the free end of the hose or hose whip may result in an injury.
I. Close nitrous oxide cylinder post valves. Connect free end of the hose to the analgesia machine
as shown in Figure 19.
CAUTION
 Nitrous oxide - oxygen should only be administered by or under the supervision of a
medical professional.
 Not all patients should receive nitrous oxide -oxygen sedation. The following
contraindications have been extracted from the referenced medical literature:
