Vent

®

 oral devices. 

The purpose of this accessory  
is to provide the Healthcare Professional an option to augment traditional 
mandibular advancement therapy. 

Why might 

ExVent

 be needed?

 Sometimes the airway needs additional 

help to stay open. This help is provided by the use of the 

ExVent

 valve, 

which provides the airway with mild “end of breath” airway pressure/
support. 

ExVent 

is intended to assist in reducing or eliminating snoring 

and/or obstructive sleep apnea.  

How does it work?

 The 

ExVent

 is inserted into the oral airway in the 

front of the O

2

Vent

®

 device. The 

ExVent

 is a valve with air vents. This valve 

opens and closes as you breathe.

 

Upon breathing in, the valve fully opens which allows for the free flow 
of air into the airway. 

 

When breathing out, the valve closes, directing your breath through 
the air vents. This creates the mild pressure or airway support 
required to keep the airway open. This type of valve is sometimes 
known as Positive End Expiratory Pressure (PEEP) or End Positive 
Expiratory Pressure (EPAP). 

The 

ExVent

 offers three different levels of airway support: low, medium and 

high. This refers to the amount of airway pressure the 

ExVent

 generates. 

Your Healthcare Professional will determine if this mode of therapy is the 
right one for you to use to reduce your snoring and/or sleep apnea. 

Indications for Use

The Oventus 

ExVent

 is an accessory that can be used with the O

2

Vent

®

 

range of oral devices to assist with the intended use of reducing or 
alleviating snoring and/or obstructive sleep apnea (OSA).

The 

ExVent

 is a one-way valve that opens when breathing in and 

closes when breathing out, prolonging the breath. This creates 
positive pressure or upper airway support and may improve user 
outcome and comfort when used with your O

Vent

®

 device. The 

ExVent

 is an optional accessory. A prescription is required.
