Smart cannula could measure your breath while giving air
NCT ID NCT06713213
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new device called FRNDS, a nasal cannula that can measure how much air a person breathes while also delivering air. Researchers compared it to standard chest belts in 57 healthy adults. The goal was to see if the cannula works as well as current methods, which could help monitor patients with breathing problems more easily.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FRNDS cannula (a device that measures breathing and delivers air)
- What this could lead to
- If validated, this device could allow real-time breathing monitoring while giving oxygen, improving care for respiratory failure.
- What could go wrong
- This was a small, early study in healthy people only. The device needs more testing in sick patients before it can be used in practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants must be healthy adults over the age of 18. Exclusion Criteria: * Adults with preexisting comorbidities including: * Chronic lung disease * Chronic heart disease * Neuromuscular disease * History of nasal surgery * History of upper airway reconstructive surgery * History of deviated nasal septum * Preferential mouth breathers * Minors, as defined by state law where the study is performed (infants, children, teenagers) * Pregnant women will be excluded, as they have physiologically altered respiratory parameters and to minimize potential mechanical discomfort due to the RIP belts. * Prisoners (including all incarcerated individuals) * Adults not capable to consent on their own behalf
