title: [Reference values for the determination of the closing volume with single breath nitrogen determination].
abstract: A simple method for the estimation of the closing volume is demonstrated and the values got from 120 healthy males are cited as reference values. The exactness of measuring in sufficient for the practical demands. The results correspond to those in literature.
