Avia Pulse DE Series

Portable Pulse Oxygen System (PPOS) for therapeutic use by customers with a pre-existing medical condition and emergency use.

Overview of the Avia Pulse DE Series

The Avia Pulse DE (Emergency) Series is a Portable Pulse Oxygen System (PPOS) designed to provide therapeutic Oxygen for airline customers who have a pre-existing medical condition and pre-book oxygen for their flight(s). The cylinder can also be used for emergency purposes. The advantage is that oxygen is only consumed during that part of the inhalation where the oxygen is of benefit and a reduced amount of oxygen is therefore needed with the consequent weight saving.

The DE series has 5 pulse settings and constant flow settings of 2 and 4 litres per minute. The system compromises of a lightweight DOT approved cylinder, available in 3 sizes; 2.0 litre, 2.7 litre and 3.2 litre water capacity with a working pressure of 200 bar.

The conserver gives extremely economical performance, releasing a bolus of oxygen as soon as it registers a small drop of pressure in the passenger's nose, it then closes very quickly, thus conserving oxygen. The conserver performance is best in class.

The regulator is of robust design and incorporates a number of safety features.

The 'cage' is designed to protect the regulator, conserver, pressure gauge, ease handling and present a softer image to the passengers and crew. It is manufactured in a flame retardant material and has a Contact Memory Button (CMB) fitted at the rear, which stores data on configuration control and traceability of the assembly in accordance with ATA Spec 2000. The assembly can also be provided with an RFID tag

A purpose designed flame retardant bag, includes pockets for the operating instructions, cannula and loops for attachment. Cannula assemblies can be supplied with an inline flow indicator, allowing cabin crew to check delivery of oxygen whilst a passenger is sleeping.

Human factors have been incorporated in to the design from the outset and Avia Technique has included a number of features following consultation with experienced airline cabin safety specialists and engineers.
