Abstract

A ventilation interface and system is described which can be adapted to be connected to a source of ventilation. The ventilation interface and system may include variable exhaust ports. The ventilation interface system may optionally include feed tubes, y-connector, tube holder, and headgear.

Claims

1. An adjustable slide interface comprising:

a substantially rectangular slide configured to be attachable to a nasal cannula with at least one flow velocity opening including a flow velocity cut out;

wherein when the substantially rectangular slide is moved laterally at least one flow velocity opening passes over the flow velocity cut out.

2. The adjustable slide according to claim 1 wherein the substantially rectangular slide mechanism is configured to snap into an exhaust port.

3. The adjustable slide interface according to claim 1 wherein the substantially rectangular slide mechanism is configured be held in an exhaust port by brackets.

4. The adjustable slide interface according to claim 1 wherein the substantially rectangular slide is made from at least one of rubber, plastic, silicone, polyethylene or polyurethane.
