Estimated central blood volume in cirrhosis [PDF]

open access: yes, 1992
The estimated central blood volume (i.e., blood volume in the heart cavities, lungs and central arterial tree) was determined by multiplying cardiac output by circulatory mean transit time in 19 patients with cirrhosis and compared with sympathetic ...

Severe pulmonary hypertension associated with lung disease is characterised by a loss of small pulmonary vessels on quantitative computed tomography

open access: yesERJ Open Research, 2022
Background Pulmonary hypertension (PH) in patients with chronic lung disease (CLD) predicts reduced functional status, clinical worsening and increased mortality, with patients with severe PH-CLD (≥35 mmHg) having a significantly worse prognosis than ...

Biventricular diastolic dysfunction, thrombocytopenia, and red blood cell macrocytosis in experimental pulmonary arterial hypertension

open access: yesPulmonary Circulation, 2020
Pulmonary arterial hypertension is a fatal disease, where death is associated with right heart failure and reduced cardiorespiratory reserve. The Sugen 5416, hypoxia and normoxia Fischer rat model mimics human pulmonary arterial hypertension, although ...

Do alterations in pulmonary vascular tone result in changes in central blood volumes? An experimental study

open access: yesIntensive Care Medicine Experimental, 2021
Background The effects of selective pulmonary vascular tone alterations on cardiac preload have not been previously examined. Therefore, we evaluated whether changing pulmonary vascular tone either by hypoxia or the inhalation of aerosolized prostacyclin

Supine, prone, right and left gravitational effects on human pulmonary circulation

open access: yesJournal of Cardiovascular Magnetic Resonance, 2019
Background Body position can be optimized for pulmonary ventilation/perfusion matching during surgery and intensive care. However, positional effects upon distribution of pulmonary blood flow and vascular distensibility measured as the pulmonary blood ...

Cardiopulmonary interactions in left heart failure

open access: yesFrontiers in Physiology, 2023
The primary impact of ventilation and ventilatory efforts on left ventricular (LV) function in left ventricular dysfunction relate to how changes in intrathoracic pressure (ITP) alter the pressure gradients for venous return into the chest and LV ...

Chest dual-energy CT to assess the effects of steroids on lung function in severe COVID-19 patients

open access: yesCritical Care, 2022
Background Steroids have been shown to reduce inflammation, hypoxic pulmonary vasoconstriction (HPV) and lung edema. Based on evidence from clinical trials, steroids are widely used in severe COVID-19.

Methodology of True Pulmonary Blood Volume Determination [PDF]

open access: yesCirculation, 1966
"True" pulmonary blood volume has been determined by three indicator-dilution methods in 96 subjects. In two methods a right or left ventricular mixing chamber is interposed between the injection and sampling sites while in the third such a mixing chamber is absent.
