The consequences of a DWI/DUI conviction are life-changing. In recent years, all 50 states have put in place ignition interlock laws. An interlock device must be installed in your vehicle, according to these laws.

However, people who have asthma or emphysema, or deal with another condition that weakens their lung capacity, face an additional issue. If that is your situation, you may be able to lower the volume to the minimum amount sufficient for the effective operation of our ignition interlock devices. To find out what it is and how it can help, read on.

What is an Ignition Interlock Device (IID)?

An ignition interlock device (IID) measures the breath alcohol concentration (BrAC) of a breath sample that the driver provides. You must blow into the device before you start to drive. The process must be repeated for any rolling retests.

For an ordinary IID, a full breath is required. But if you have a condition like asthma, COPD, or emphysema, you may not be able to provide a sufficient sample. And if you can’t provide a sufficient breath sample, the device won’t work.

What is a Reduced Lung Capacity Interlock Device?

In recent years, ignition interlock providers, the courts, and state agencies have become aware that some individuals don’t have the lung capacity to pass a breath test administered by a standard ignition interlock. However, the law still applies to them. These people need a device that is adjusted to require a smaller breath sample to function.

Reduced Lung Capacity Interlock: Things to Remember

Not all states allow the provider to lower the volume to the minimum amount. That means they won’t always adjust the ignition interlock so that it accepts a smaller breath sample. You should check with your attorney, ignition interlock program authority, or DMV to see if your state provides this opportunity.

If you use an inhaler to help you breathe, avoid using it before you blow into the device. The same rule goes for using toothpaste, mouthwash, and other products that contain alcohol. Ethanol and other chemicals in your inhaler can trigger a failed test on your ignition interlock device.

Draeger US Interlock and Lung Capacity Interlock Devices

One of the leading interlock providers, Draeger US Interlock, has responded to the needs of their customers with limited lung capacity. They meet this challenge by adjusting the volume of the device when a customer cannot provide a full breath. However, Draeger US Interlock does not change the standard ignition interlock breath volume setting except for when it receives the appropriate authorization:

●    Draeger US Interlock must receive approval from the court or the legal jurisdiction to lower the breath sample volume. OR

●    Draeger US Interlock must receive documentation from a licensed physician that verifies your diminished lung capacity and demonstrates that your device needs to be adjusted.

●    Depending upon the state you live in, you may also need additional approval from the state authority.

So, Draeger US Interlock must receive all the required authorization first. Then, it will reduce the volume of the device to the minimum amount needed for it to operate.
