Avisar Spec

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.
