Fremgangsmåde til at kompensere for effekten af recirkulation af blodoplöselig gas på bestemmelse af pulmonal blodgennemströmning i gentagne tests med genånding af inert gas

摘要

The present invention discloses a method to compensate for a non-zero mixed venous partial pressure of inert blood soluble gas when determining physical parameter(s) of a patient in successive inert gas rebreathing tests. The method comprises the steps of: obtaining the partial pressure of said inert blood soluble gas inhaled and/or exhaled by said patient in a period prior to said successive rebreathing test; obtaining the partial pressure of said inert blood soluble gas inhaled and/or exhaled by said patient in said successive rebreathing test; determining said physical parameters) using said partial pressure of said inert blood soluble gas inhaled and/or exhaled by said patient and obtained in said period prior to said successive rebreathing test and said partial pressure of said inert blood soluble gas inhaled and/or exhaled by said patient and obtained in said successive rebreathing test. Furthermore the present invention relates to a corresponding system and computer-readable medium.
