Air Next spirometer has an expected life span of 10 years. Replace the batteries when they are running low on power.

Take a seat.
Raise your chest and chin so that you can breathe easily.
Relax and breathe normally a couple of times without the spirometer.
Inhale deeply. Completely fill your lungs with air, and hold it.
Bring the spirometer to your mouth. If you do this too fast the turbine would start early, this can be avoided if you bring it in from the side.
Tightly seal your lips AROUND the mouthpiece.
Be careful not to cover the hole with your tongue or your teeth.
Blow as hard and as fast as you can.
Keep going until you have completely emptied your lungs.
Rest for a bit and catch your breath before doing the next test.

It contains the Air Next Spirometer that connects to your smartphone via Bluetooth, one replaceable disposable single use turbine, one cotton bag, two AAA batteries and the user manual.

Lung age is a good tool to help patients understand the extent to which their lungs have been affected by external factors such as smoking.

Lung age is computed in accordance to the 1985 paper by J. F. Morris and W.Temple.

Normal results for a spirometry test vary from person to person. They are based on your age, height, race, and gender. NuvoAir calculates the predicted normal value for you before you do the test with the information provided in your profile.

Obstruction and restriction are determined according to the standard ATS/ERS decision tree (figure 2 in the reference below).

When obstruction is observed, its severity is computed according to ATS/ERS standards (table 6 in the reference below).

When restriction is observed, its severity is computed as:

  • 60% ≤ FVC PERCENT PREDICTED < 80% → MILD RESTRICTION
  • 50% ≤ FVC PERCENT PREDICTED < 60% → MODERATE RESTRICTION
  • FVC PERCENT PREDICTED < 50% → SEVERE RESTRICTION

NuvoAir Home is available in English, French, German, Italian, Spanish, Swedish and Dutch.

Yes, to use NuvoAir Home you need a Provider Code, which is provided by your hospital. In this way we ensure that your data is shared and reviewed by the right clinical team.

The grading is based on how well tests are performed and how reproducible they are, meaning how consistent the attempts are in a session. An acceptable test is a test performed without errors, such as stopping exhaling before the lungs are completely empty.

A - EXCELLENT

At least 3 acceptable maneuvers.
For adults, top-two FVC and FEV1 from such maneuvers are within 150 mL.
For children aged 2-6, top-two FVC and FEV1 from such maneuvers are within 100 mL or 10% of the highest result (whichever is greater).

B - VERY GOOD

At least 2 acceptable maneuvers.
For adults, FVC and FEV1 from such maneuvers are within 150 mL.
For children aged 2-6, FVC and FEV1 from such maneuvers are within 100 mL or 10% of the highest result (whichever is greater).

C - GOOD

At least 2 acceptable maneuvers.
For adults, FVC and FEV1 from such maneuvers are within 200 mL.
For children aged 2-6, FVC and FEV1 from such maneuvers are within 150 mL or 10% of the highest result (whichever is greater).

D - POOR

At least 2 acceptable maneuvers.
For adults, FVC and FEV1 from such maneuvers are within 250 mL.
For children aged 2-6, FVC and FEV1 from such maneuvers are within 200 mL or 10% of the highest result (whichever is greater).

E - VERY POOR

One acceptable maneuver.

F - NOT ACCEPTABLE

No acceptable maneuver.

NuvoAir identifies some of the most common errors performed during a spirometry test.

Back-Extrapolated Volume (BX)
If the start of the exhalation is slow, or moving the spirometer has caused the turbine to spin before the actual exhalation, this will be detected as an error of Back-Extrapolated Volume (Volume being recorded before the actual attempt).
Trigger: Back-extrapolated volume > 5% of FVC or 150 mL, whichever is greater

Time to Peak (TP)
If the start of the exhalation is slow, the peak flow will come too late. This is usually happens if the attempt was not done as fast and as hard as possible.
Trigger: Time to peak > 85 ms

Cough (CO)
The forced exhalations can cause you to cough. Coughs can create errors in the volume measured.
Trigger: Cough is detected in first 2 seconds

Early Termination (ET)
If you stop exhaling before you have completely emptied your lungs, this will be detected as an early termination.
Trigger: Flow in last sample of Flow array > 0.2 L/s

Cessation (CE), also known as Glottis Closure or Breath Holding
If the glottis closes before you have completely emptied your lungs, this will be detected as an early cessation.
Trigger: Volume change in last second > 0.025 L

NuvoAir does not implement the 6s rule for test length since test duration varies between patients. Instead we stop test recording when the turbine stops spinning for over 1 second. Turbine rotation is finally converted to human flow via a fluid dynamics algorithm.

Troubleshoot

After each trial you can see the result directly on the screen. The result screen will display the flow-volume curve, FEV1, FVC, the ratio between FEV1/FVC and PEF as well for how long you have exhaled. With NuvoAir Home, you can add up to 5 tests in one session, for Air MD, up to 8. The app will automatically display the best curve and results for you. Please note that spirometry guidelines recommend at least 3 tests per session.

The Air Next Spirometer needs to be correctly connected to the smartphone via Bluetooth. Make sure the app has permission to access Bluetooth, and that Bluetooth is turned on. If you are using an Android phone, then Location Permission is required for the app to be able so scan for the Air Next.
