Avisa is in the final stages of developing the AVISAR SPEC™ instrument. The AVISAR SPEC contains a touchscreen operator interface, nebulizer controller, breath sampling pneumatics and a laser spectrometer. The AVISAR SPEC™ rapidly measures breath 13CO2/12CO2 isotopic ratios using near infrared wavelength modulation spectroscopy enabled by a patented, tunable semiconductor laser. Major design innovations have resulted in a compact, portable device weighing about 9 pounds (4 kg) that is deployable in point-of-care settings such as clinics, hospital wards and intensive care units.
The Avisa BreathTestTM is currently an investigational device and has not yet been approved by the FDA for commercial use.
