Intended Use

The Vapotherm Transfer Unit (VTU) allows the mobile delivery of high-flow humidified respiratory therapy within a
hospital environment. With a fully charged battery module and full gas cylinders, the length of available mobile
therapy depends on 2 factors:

 Cylinder gas supply: From 14 minutes to 18.7 hours, based on the O2/air gas ratio and flow rate settings

on the Precision Flow.

 Battery life: Up to 1.5 hours from a full charge.

o Tripp Lite recommends that the Power Supply be plugged into a wall outlet, charging the battery as

often as possible. Charging the batteries for brief intervals DOES NOT adversely affect battery
performance. However, leaving the batteries fully discharged for long periods of time DOES
adversely affect battery performance.

o For long term storage, the battery should be fully charged at a minimum of once per month.

The VTU consists of the

 GCX Roll Stand
 Medical-Grade Mobile Power Kit
 Medical Air and Oxygen Manifold and E-Cylinder Holder

 Vapotherm Precision Flow (Optional)
