Barokamrában hypoxiában virtuális (VR)2 repülés alatti vizsgálati eredményeink megerősítik, ellentmondó kompenzációs mechanizmusok, szív–agy- tengely kiszámíthatatlan stresszreakciója miatt agysejtekben elhúzódó oxigénfelhasználási zavar léphet fel. korszerű vadászgépeken bekövetkező hypoxiás halálesetek UPE3-elemzése különösen indokolt Covid–19-világjárvány okozta megbetegedés után, amikor vírusfertőzés tüdőgyulladás légzőfelszínvesztés (ARDS)4 gyógyulás után is, jelleggel tovább rontja fenti élettani folyamatokat.
