Effects on the pulmonary hemodynamics and gas exchange with a speed modulated right ventricular assist rotary blood pump: a numerical study

open access: yesBioMedical Engineering OnLine, 2018
Rotary blood pumps (RBPs) are the newest generation of ventricular assist devices. Although their continuous flow characteristics have been accepted widely, more and more research has focused on the pulsatile modulation of RBPs in an attempt to provide ...

Prognostic value of pulmonary dead space in patients with the acute respiratory distress syndrome. [PDF]

open access: yes, 2011
A study published in the previous issue of Critical Care demonstrates that measurement of the pulmonary dead-space fraction is superior to hypoxemia as an indicator of a favorable physiologic response to prone positioning in patients with severe acute ...

Vascular Growth in the Fetal Lung [PDF]

open access: yes, 2011
The structure of the lung is truly remarkable. It is primarily composed of three branched tubular networks (the airway, pulmonary artery and vein, bronchial artery and vein) which supply blood and air to the site of gas exchange and which maintain ...

Anomalous systemic arterial supply to the left lower lung lobe: A case report

open access: yesFrontiers in Medicine, 2022
BackgroundAn anomalous systemic arterial supply to the lung lobes is a rare congenital pulmonary vascular malformation. Current treatments include thoracoscopic lobectomy, anatomical segmentectomy, simple ligation and arterial embolization.

Nitric Oxide in Experimental Pulmonary Embolism [PDF]

open access: yes, 2010
Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination.

Pulmonary arteriovenous malformations with pulmonary artery hypertension: Therapeutic implication

open access: yesAPIK Journal of Internal Medicine, 2020
Pulmonary arteriovenous malformations (PAVMs) are rare pulmonary vascular anomalies and represent fistulous connection between arterial and venous branches without customary intervening capillary network that is vital for gas exchange. The incidence is 2–

Reassessment of the evidence for postcranial skeletal pneumaticity in Triassic archosaurs, and the early evolution of the avian respiratory system. [PDF]

open access: yes, 2012
Uniquely among extant vertebrates, birds possess complex respiratory systems characterised by the combination of small, rigid lungs, extensive pulmonary air sacs that possess diverticula that invade (pneumatise) the postcranial skeleton, unidirectional ...

Early stage nonclinical pulmonary disorder in COVID-19 may present asymptomatic and fuel the contagion

open access: yesMilitary Medical Research, 2021
Evidence shows that pulmonary problems in coronavirus disease 2019 (COVID-19) may set off from vascular injury that progresses to physiological disturbances through a compromised gas exchange, following an infection with the severe acute respiratory ...

A modeling-based evaluation of isothermal rebreathing for breath gas analyses of highly soluble volatile organic compounds

open access: yes, 2011
Isothermal rebreathing has been proposed as an experimental technique for estimating the alveolar levels of hydrophilic volatile organic compounds (VOCs) in exhaled breath.
