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.

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

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.
