# My Avthor won't show an Air Leak.

#### ![Line Divider-SMALL](https://help.avkin.com/hs-fs/hubfs/Line%20Divider-SMALL.png?width=574&name=Line%20Divider-SMALL.png)An air leak looks like a rapid boil in the air leak monitor. Small bubbles in the air leak monitor are normal and may be seen during tidaling and fluctuation. If this is not functioning for your Avthor make sure the “open to air” slider is turned on in the Avkin app.

This tubing connection may look different depending on the CDU that is sent. You will not be able to see the air leak without a suction unit.![suction connect ](https://help.avkin.com/hs-fs/hubfs/suction%20connect%20.png?width=424&name=suction%20connect%20.png) ![Connect that suction](https://help.avkin.com/hs-fs/hubfs/Connect%20that%20suction.png?width=400&height=200&name=Connect%20that%20suction.png)

#### Also, check your tubing to ensure that there is not a backup of blood. If there is too much blood within the system, it will prevent showing an air leak.
