Model Spir-0 -Breathing Cycle Monitor

Spir-0 is an innovative subject breathing activity monitoring tool, extremely compact and simple to use. Its operating principle is based on a fiber optic sensor which makes it compatible with use in MRI, fMRI and EEG environments and applications. Spir-0 is able to accurately measure the respiratory behavior of a subject by detecting small variations in the air flow during the inhalation and exhalation phases of a subject breathing and thus provide an accurate representation of the entire respiratory cycle. A further advantage is the very low invasiveness of the sensor: all that is needed is to position the terminal part of the optical fiber (a tube with a diameter of less than a millimeter) in the entrance to one nostril from which system will be able to perform an automatic calibration step followed by monitoring and recording for the subjects breathing.
