SERIAL NUMBER IDENTIFICATION

1-2 Introduction
The Companion 1000/T is a portable liquid oxygen unit that supplies supplemental
medical oxygen at prescribed flowrates to the patient. A patient fills the unit with liquid
oxygen from a Companion Stationary reservoir. When full, the Companion 1000/T
holds about 3.1 lbs (1.4 kg) of liquid oxygen in a double-walled, vacuum-insulated
container. The liquid oxygen is vaporized into gas in a heat exchange system. The
gaseous oxygen is warmed to near room temperature and delivered to the patient at a
selectable, metered flowrate. Flowrates up to 6 L/min are available from the Companion
1000 while flowrates up to 15 L/min are available from the Companion T. A patient
will typically receive about eight hours of continuous flow oxygen at a flow setting of 2
L/min. The liquid oxygen contents of the Companion 1000/T is measured by a weight
scale that is activated by suspending the unit by one end of the carrying strap. An
external moisture collection cup is attached to the bottom of the Companion T. This
easily removable cup collects the additional condensed water that is created when the
Companion T is operated at higher flowrates.
The serial number on a Companion 1000/T is etched on the vent valve mounting
bracket (Figure 1-3). The vent valve lever must be pulled down to view the serial
number when the unit side covers are in place. The serial number designates the year,
month, and day of manufacture as well as the production number.
