alveoflow Neo · India's first portable oscillometry
Breathe normally.
That's the test.
India's first portable oscillometry device, designed and built in India. Airway resistance and reactance, measured while the patient breathes quietly.
- India's first portable oscillometry
- Patent pending
- Design applied for
Designed to be held
Light in the hand. Ready in seconds.
One device, one mouthpiece, no cart.
Tidal breathing
15–30 seconds of quiet breathing.
No forced blow. No coaching.1
Results on the device
Six numbers, right on screen.
R5, R19, X5, AX and Fres against predicted.
Quality built in
Accepted. Compared to predicted.
Checks for leaks, swallows and coherence before a result is kept.
Test the patients spirometry can't.
Spirometry needs a maximal, coached blow. Oscillometry measures during the breathing the patient is already doing.
Forced spirometry
- Maximal breath in, then a hard, fast, sustained blow
- Coaching, repeat attempts, acceptability criteria
- Hard for young children, older adults and anyone breathless at rest
alveoflow Neo
- Quiet breathing through the mouthpiece
- No coaching, no maximal effort, no learned technique
- Separates resistance at low and high frequency
Oscillometry complements spirometry. Run Neo and alveoAir Ultra in the same visit when both are needed.
Six numbers.
The whole airway tree.
The device coaches the test.
A 3.5-inch screen guides the operator from first breath to accepted result.



Take a closer look.



Measured to the ERS standard.
Every result, straight to the Hub.
Neo sends each recording wirelessly to alveo Hub, where it joins the patient's spirometry in one record.

Better with alveo Hub
Every Neo test, in the patient's record.
Each recording lands on the Hub next to the patient's spirometry and walk test. Works offline, and syncs to alveoConnect when you are online.
