Use of Noninvasive Gas Exchange to Track pulmonary Vascular Responses to exercise in Heart Failure

open access: yesClinical Medicine Insights: Circulatory, Respiratory and Pulmonary Medicine, 2013
We determined whether a non-invasive gas exchange based estimate of pulmonary vascular (PV) capacitance [PV CAP = stroke volume (SV) x pulmonary arterial pressure (Ppa)] (GX CAP ) tracked the PV response to exercise in heart-failure (HF) patients ...

Significance of Pulmonary Endothelial Injury and the Role of Cyclooxygenase-2 and Prostanoid Signaling

open access: yesBioengineering, 2023
The endothelium plays a key role in the dynamic balance of hemodynamic, humoral and inflammatory processes in the human body. Its central importance and the resulting therapeutic concepts are the subject of ongoing research efforts and form the basis for

Gas Exchange and Mechanical Properties of the Lung in Miners with Severe Concomitant Injury

open access: yesОбщая реаниматология, 2007
Objective: to study the specific features of pulmonary gas exchange and mechanical properties in various manifestations of respiratory failure in miners with severe concomitant injury, who have a service length of 10 years or more, in order to optimize ...

Optimized ventilation power to avoid VILI

open access: yesJournal of Intensive Care, 2023
The effort to minimize VILI risk must be multi-pronged. The need to adequately ventilate, a key determinant of hazardous power, is reduced by judicious permissive hypercapnia, reduction of innate oxygen demand, and by prone body positioning that promotes

Effect of hypoxia and hyperoxia on exercise performance in healthy individuals and in patients with pulmonary hypertension: A systematic review [PDF]

open access: yes, 1996
Exercise performance is determined by oxygen supply to working muscles and vital organs. In healthy individuals, exercise performance is limited in the hypoxic environment at altitude, when oxygen delivery is diminished due to the reduced alveolar and ...

Impact of Detoxification Techniques on Pulmonary Gas Exchange Function in Patients with Generalized Peritonitis

open access: yesОбщая реаниматология, 2012
Objective: to analyze the impact of different detoxification techniques on pulmonary gas exchange function in patients with generalized peritonitis complicated by multiple organ failure. Subjects and methods.

Severe Pulmonary Arteriopathy Is Associated with Persistent Hypoxemia after Pulmonary Endarterectomy in Chronic Thromboembolic Pulmonary Hypertension. [PDF]

open access: yesPLoS ONE, 2016
Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by occlusion of pulmonary arteries by organized chronic thrombi. Persistent hypoxemia and residual pulmonary hypertension (PH) following successful pulmonary endarterectomy (PEA) are ...

Intrapulmonary shunting and pulmonary gas exchange during normoxic and hypoxic exercise in healthy humans [PDF]

open access: yes, 2008
Exercise-induced intrapulmonary arteriovenous shunting, as detected by saline contrast echocardiography, has been demonstrated in healthy humans. We have previously suggested that increases in both pulmonary pressures and blood flow associated with ...

Simultaneous Measurement of Lung Diffusing Capacity and Pulmonary Hemodynamics Reveals Exertional Alveolar‐Capillary Dysfunction in Heart Failure With Preserved Ejection Fraction

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Hemodynamic perturbations in heart failure with preserved ejection fraction (HFpEF) may alter the distribution of blood in the lungs, impair gas transfer from the alveoli into the pulmonary capillaries, and reduce lung diffusing capacity.
