recommendations! Published in 2019 at "COPD: Journal of Chronic Obstructive Pulmonary Disease"

DOI: 10.1080/15412555.2019.1631776

Abstract: Abstract Combining measurements of impaired lung mechanics (inspiratory constraints) with an index of increased respiratory stimuli to metabolic demand (poor ventilatory efficiency) might enhance the ability of cardiopulmonary exercise testing (CPET) in exposing a mechanistic… read more here.

DOI: 10.1093/eurheartj/ehae666.189

Abstract: The role of cardiopulmonary exercise test (CPET) in hypertrophic cardiomyopathy (HCM) has been previously examined, revealing two prognostic parameters: peak Vo2 and the VE/VCO2 slope. Specifically, individuals with a VE/VCO2 value above 31 (ventilator inefficiency)… read more here.

recommendations! Published in 2019 at "European Respiratory Journal"

DOI: 10.1183/13993003.00342-2019

Abstract: Cardiopulmonary exercise testing (CPET) is an important tool for assessing functional capacity and prognosis in pulmonary arterial hypertension (PAH). However, the associations of CPET parameters with the adaptation of right ventricular (RV) function to afterload… read more here.

recommendations! Published in 2025 at "Annals of Intensive Care"

DOI: 10.1186/s13613-025-01427-1

Abstract: The association between bedside ventilatory parameters—specifically arterial carbon dioxide pressure (PaCO2) and ventilatory ratio (VR)—and mortality in patients with acute respiratory distress syndrome (ARDS) remains a topic of debate. Additionally, the persistence of this association… read more here.

DOI: 10.3389/fphys.2022.1002238

Abstract: Background and objective: Along with impaired aerobic capacity, increased slope of the relationship between ventilation (VE) and pulmonary CO2 output (VCO2), i.e., VE-VCO2 slope is a common finding in patients with cardiac amyloidosis (CA), which… read more here.
