INTRODUCTION
INVACARE VENTURE DEMAND OXYGEN DELIVERY DEVICE
Ordinary oxygen supply units deliver oxygen continuously.
The normal breathing pattern is to inhale about
In contrast, the Venture Demand Oxygen Delivery Device (Venture DODD) senses your inhalation and instantly releases a programmed pulse of oxygen at a specified flowrate at the beginning of inhalation.
The specified flowrate of oxygen is delivered within the first second of inhalation. Oxygen is not delivered during exhalation. This means that your oxygen use time is extended by the ratio of breath duration over the pulse duration. Venture DODD will extend user time an average of four (4) times in the Variable duration breath mode.
Comfort is another advantage of the Venture DODD. Nasal drying caused by continuous flow is eliminated, as oxygen is only delivered during inhalation. Therefore, additional humidification is not necessary. Since the oxygen is delivered at normal flowrates, there is not a high blast of oxygen to the end user, which makes the Venture DODD more comfortable than other pulse systems.
The Venture DODD can be used in the traditional continuous flow mode simply by turning the Venture DODD device OFF. Effective flow deliveries of
0.5to 6 liters per minute (L/min.) can be instantly selected, in pulse or continuous mode, by each individual as prescribed by your physician. During pulse mode, the Venture DODD runs on a disposable
NOTE: Actual Battery use time depends on your breathing rate.
The Venture DODD can be used with compressed gas or liquid oxygen systems. Both 20 and 50 psig units were designed for use on 20 and 50 psig oxygen delivery systems, respectively.
NOTE: The 50 psig system should ONLY be used with the threaded (DISS) fitting, and NOT the
