Dus er is wel ventilatie maar geen perfusie (zoals bij een longembolie) of wel perfusie maar geen ventilatie (pulmonale shunt). Voor beide situaties geld dat er een hypoxemie kan optreden maar dat gebeurd lang niet altijd. groet. erik kapteijns

WebApr 10, 2024 · The shunt was reduced in phenotype L but increased in phenotype H due to PEEP, with a corresponding P =.048 difference. PEEP had a variable effect on V̇/Q̇ mismatch. On average, higher levels could not reduce shunt in patients with COVID-related ARDS ventilated with invasive mechanical support for more than 48 hours. WebThis is referred to as ventilation/perfusion (V/Q) mismatch. There are two types of V/Q mismatch. Both produce dead space, regions of broken down or blocked lung tissue. ...

WebNov 17, 2016 · A shunt occurs when blood exits the heart without having participated in gas exchange. A shunt can be viewed as an extreme V/Q mismatch (see Fig. 68-4). There are two types of shunt: anatomic and intrapulmonary.
