[Prognostic value of functional methods of studying respiration and circulation in lung cancer surgery].

The method of stepwise regression analysis with the help of computer was used for a retrospective analysis of the prognostic value of indicators of the external ventilation and central hemodynamics (with special reference to age and volume of surgery) in 104 men with lung cancer. It was found that an analysis of these factors is enough for predetermination of duration of the postoperative period in its not complicated course. The priority of the estimation of the adaptive abilities of the circulation for such prognosis has been shown. The value of the method of integral rheography and the system of estimation of the indicators of central hemodynamics developed on its basis has been confirmed.
