tremoFlo P-100

Airwave Oscillometry System for Large Animals

The tremoFlo P-100 Airwave Oscillometry System (AOS) is a portable lung function testing instrument that can measure respiratory mechanics in large animals (dogs, NHPs) non-invasively. The system comprises a lightweight handheld device attached to a cradle unit. Subjects breath directly into the handheld unit during measurements via a disposable anti-bacterial/viral filter and a subject mask. The tremoFlo software provides subject management, testing and result interpretation capabilities.
