Clinical Questions

How does the device work?

AirSonea acts much like the stethoscope your doctor uses when listening to your lungs. By placing the sensor on your trachea [windpipe] for 30 seconds of normal breathing, the device can record and then analyze your breath sounds for the presence of wheezing. The recorded breath sounds are analyzed with our advanced algorithms to detect, quantify and measure wheeze, an important sign of air flow obstruction in asthma.

What does WheezeRATE mean?

WheezeRATE is the amount of wheeze detected during 30 seconds of normal breathing. It is expressed as a percentage of wheezing over the 30 seconds. Wheezing is a sign of airflow obstruction and typically indicates breathing difficulty.

What’s a normal WheezeRATE?

There are a number of causes of wheezing and it is always abnormal. The degree of tolerated wheezing (WheezeRATE) will vary from user to user. Monitoring with AirSonea may help your doctor evaluate your WheezeRATE trend.

Why does AirSonea give me two WheezeRATE numbers?

The main result is the conventional WheezeRATE including ambient wheeze rejection. Wheezes and other sounds that are heard in the ambient environment are not taken into consideration in the calculation.
The smaller number is the WheezeRATE without ambient wheeze rejection. Wheezes and other sounds that are heard in the environment are also taken into consideration in the calculation. Only refer to this WheezeRATE value where directed by your healthcare provider (such as when you are diagnosed with an audible wheeze due to vocal cord dysfunction).


Technical Questions

I have paired by AirSonea to my phone successfully, now I want to pair it to another phone. Is there a way to do this?

AirSonea uses Bluetooth® communications to connect the device to your phone. There can only be a single connection between the device and a phone. To pair your AirSonea to another phone, you need to go into your Bluetooth settings on the currently paired phone and un-pair. Once this is completed, you can pair the device to another phone.

The instructions for pairing my phone with AirSonea do not work.

The pairing of Bluetooth devices may be different depending upon the phone and operating system. You can find compatibility for the AirSonea device by going to For more information about pairing Bluetooth devices see your phone’s manual.

Why do I get a “Too Much Noise” error message?

It is important that you use the AirSonea in a very quiet place, just as your doctor does when using a stethoscope. If there is noise such as music, talking, or traffic, the device may not be able to filter these sounds outs in order to properly measure your WheezeRATE.

When I take a measurement the app states that no breath sounds were detected. What is wrong?

Placement of the sensor is critical to getting a good measurement. The sensor must be placed on the trachea or windpipe. To ensure proper placement use your fingers to locate the hard “Adams Apple” on your neck and place the sensor there.

To save power I turned off my Bluetooth®. When I did this I could no longer perform a WheezeRATE measurement with my AirSonea phone app. What should I do?

To measure a WheezeRATE, the AirSonea App requires a Bluetooth connection between your phone and the AirSonea sensor. Though all other features except WheezeRATE measurement are available when Bluetooth is turned off, you will need to turn Bluetooth back on to perform a WheezeRATE measurement.
