title: On-line computation of dead space and nitrogen clearance curve.
abstract: This work is aimed at getting on-line values of dead space and nitrogen clearance curves during washout experiments performed during continuous oxygen inhalation. An analog computer was built and connected to standard numeric implements, sending to them the processed signals from the measuring instruments. This solution seems to give at the same time good accuracy and good versatility at the lowest cost both in time and money.
