Computer data acquisition system for CO₂ response curves

This paper describes a computer controlled data acquisition system which measures V̄(E), P(ET)CO₂, P₁₀₀ and also generates the signal for controlling the airway occlusion valve. The data are stored on disk and can be recalled for editing and plotting or statistical analysis. The system has the advantage of being portable, thus giving an anesthesiologist the flexibility of being able to measure patient responses in the operating room and or recovery room.
