The Ambistik is a high-precision, USB-based module designed to monitor environmental conditions temperature, barometric pressure, and humidity with total accuracy. This data is continuously fed into the BLUE CHERRY® software suite, enabling the system to perform real-time BTPS (Body Temperature, Pressure, and Saturated) corrections.
Why Environmental Accuracy Matters In pulmonary function testing, precision is paramount. Lung function is measured at a constant body temperature of 37°C. As exhaled air cools, its volume decreases; even a small temperature variance of 2°C can result in a 1% deviation in measured results.
Furthermore, atmospheric pressure—which fluctuates significantly between sea level and high altitudes—and humidity levels directly impact gas volume and oxygen concentration. Without accurate, real-time correction for these variables, diagnostic data can be compromised. The Ambistik eliminates this risk by providing a continuous stream of ambient data, ensuring every measurement is standardised and clinically valid.
