[Quantitative analysis of the relationship between arterialization of blood and irregularities of ventilation--perfusion ratios].

: Comparative data on the quantitative analysis of the relationship between arterialization and irregularity of the ventilation perfusion ratios are presented for a simple two-component lung model and for a model with a logarithmically normal distribution of VA/Q. A possibility of respiratory failure existence without material shifts in the arterial blood gas composition is substantiated.
