NCT04355754
During Covid-19 pandemic many patients require mechanical ventilation due to disastrous impact of SARS-CoV-2 on lungs. In several countries there is a shortage of ICU beds and ventilators. Critically ill patients are treated outside ICUs. Doctors are facing ethical dilemmas who they should treat with ventilation, who should receive ventilator and who should but will not. In ICUs or step down units or in nursery homes there are also patients beyond hope treated - very often they are dependent on mechanical ventilation. Some attempts to invent a device that could replace complex machines in patients with anticipated poor outcome have been made. Ventil was used in clinical scenarios for separate lung ventilation with good effect. As a flow divider it has a potential to ventilate 2 patients at the same time. In the study Ventil will ventilate one patient and instead of the second there will be an artificial lung. Tidal volumes, minute ventilation, PEEP set and final will be checked. Ppeak, Pmean, Pplat, Cdyn, airway resistance, EtCO2, Sat O2, HR, SAP, DAP will be monitored every 2 hrs, as well as blood-gas analysis (every 8 hrs).
NCT03667391
The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Taiwan, the incidence of CTEPH and its clinical features are unknown. This study aims at evaluating the prevalence, clinical characteristics, and management of CTEPH in a Taiwanese cohort. Primary objective: \- To investigate the geodemographics of CTEPH in Taiwan Secondary objectives: * To characterize the demographics and clinical presentation of patients with CTEPH * To describe the real-world management and treatment outcome of patients with CTEPH * To identify the risk factors of CTEPH * To assess the relationship between risk factors/patients' characteristics and clinical outcomes for CTEPH * To evaluate the prognosis of CTEPH in Taiwan using survival assessment
