Pulmonary gas exchange in response to rebreathing-induced hypoxia

, 2023
Rebreathing-induced hypoxia elicits changes in pulmonary gas exchange variables. PURPOSE: This report aims to determine the changes in pulmonary gas exchange variables in response to a rebreathing-induced hypoxia protocol in individuals who are healthy ...

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

Frontiers 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.

Pulmonary shunt in critical care: a practical approach with clinical scenarios

Journal of Anesthesia, Analgesia and Critical Care
Background Pulmonary shunt refers to the passage of venous blood into the arterial blood system bypassing the alveoli-blood gas exchange. Pulmonary shunt is defined by a drop in the physiologic coupling of lung ventilation and lung perfusion.

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

Military 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 ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Pulmonary arteriovenous malformations with pulmonary artery hypertension: Therapeutic implication

APIK 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–

Pulmonary gas exchange in elderly subjects [PDF]

European Respiratory Journal, 1996
Although important alterations in structure and function develop with age, the hypothesis that the lungs are capable of maintaining adequate gas exchange for the maximum human life span is generally accepted. This hypothesis was examined by measuring arterial oxygen and carbon dioxide tension (Pa,O2 and Pa,CO2) alveolo-arterial differences in oxygen ...
