VIASYS Healthcare Inc.’s Neuro Care Division announced the introduction of SNAP, a monitoring tool using handheld computer technology. SNAP is a single-channel EEG device that transforms a Handspring Visor handheld PDA into an EEG monitoring tool for tracking anesthesia’s effect on brain activity. As a supplement to monitoring hemodynamic changes and patient reaction to stimuli, SNAP enables anesthesia professionals to measure the effects of anesthesia on EEG in real time. SNAP is unique because it uses both the low- and high-frequency components of the EEG signal. A derived EEG measurement, the SNAP Index indicates the patient’s brain activity level, which is processed for display in a time-based trend.
