SmartLab is a flexible data acquisition system featuring Insight Software for the measurement and analysis of respiratory signals in research applications. The base module can accept up to four sensor modules for measuring flow from Rudolph Pneumotachs and airway or other pressures or a voltage input from an external device. Optional inputs include an oximeter, O2 Sensor, CO2 sensor, temperature and humidity and digital I/O. The PC software provides real time graphs and calculations of many common respiratory parameters. Data can be saved for analysis or replayed while custom software modules can be developed for special applications.
