Title (EN) APPARATUS FOR EXAMINING A PATIENT'S PULMONARY FUNCTION
(FR) APPAREIL D'EXAMEN DE LA FONCTION PULMONAIRE D'UN PATIENT
Abstract:
(EN) Apparatus for examining pulmonary function parameters of a patient comprises a rebreathing system (1-6) adapted to be connected with the patient and including a variable-volume reservoir (1), a carbon dioxide absorber (19) in an inhalation conduit (3), and means (24) for selectively switching the carbon dioxide absorber (19) on and off. A carbon dioxide meter (25) is controllable to selectively measure the carbon dioxide content of respiratory gas being exhaled and of exhaled respiratory gas collected in the reservoir (1). Volume monitoring means (17, 18) monitor the volume variations of the reservoir (1). A computing unit (30) computes the pulmonary blood flow and other pulmonary function parameters using carbon dioxide concentration parameters measured by means of the carbon dioxide meter (25) and ventilatory rate parameters measured by means of the monitoring means (17, 18).
(FR) Un appareil d'examen des paramètres de la fonction pulmonaire d'un patient, comprend un système de rerespiration (1 à 6) adapté pour être relié au patient, et comprenant un réservoir (1) à volume variable, un absorbeur (19) de dioxyde de carbone dans un conduit d'inhalation (3) ainsi qu'un moyen (24) de commutation sélective en circuit et hors circuit dudit absorbeur (19) de dioxyde de carbone. Un compteur (25) de dioxyde de carbone peut être régulé afin de mesurer sélectivement la teneur en dioxide de carbone de gaz respiratoire expiré, collecté dans le réservoir (1). Des moyens (17, 18) de contrôle de volume, contrôlent les variations volumiques du réservoir (1). Une unité de calcul (30) calcule le flux sanguin pulmonaire ainsi que d'autres paramètres de la fonction pulmonaire, à l'aide de paramètres de la concentration en dioxyde de carbone, mesurés au moyen du compteur (25) de dioxyde de carbone, et de paramètres de vitesse de ventilation mesurés à l'aide des moyens de contrôle (17, 18).
