Plaušu ventilācija Gāzu maiņa Hipoksija Pieaugoša submaksimāla slodze Hipoksiskā ventilatorā atbilde Bioloģija

description

Darbā tika pētīts, kā akūta fiziska slodze hipoksiskos apstākļos ietekmē plaušu ventilāciju un tās raksturojošo lielumu – elpošanas frekvences un elpošanas tilpuma parametrus un gāzu maiņas efektivitāti. Pētījumā tika iekļauti 10 vīriešu slodzes testa rezultāti. Katrs dalībnieks divas reizes veica pieaugošas submaksimālas veloergometriskas slodzes testu – vienu normoksiskos (21% FiO2), bet otru – hipoksiskos (15% FiO2) apstākļos. Tika secināts, ka akūtas hipoksijas apstākļos vērojama arteriālā hipoksēmija, kas padziļinās proporcionāli fiziskās slodzes intensitātei. Slodzes laikā hipoksijā plaušu ventilācija pieauga, palielinoties elpošanas tilpumam, taču ne elpošanas frekvencei. Būtiski paaugstināta elpošanas efektivitāte tika novērota hipoksiskos apstākļos kombinācijā ar submaksimālas intensitātes slodzi.
