OBJECTIVES: The ratio between PaO2 and FIO2 is used as a marker for impaired oxygenation and acute respiratory distress syndrome classification. However, any discrepancy between FIO2 and O2 fraction in the alveolus affects the PaO2/FIO2 ratio. Correc

Rationale and Objectives In this study, we compared a newly developed multibreath simultaneous alveolar oxygen tension and apparent diffusion coefficient (PAO2-ADC) imaging sequence to a single-breath acquisition, with the aim of mitigating the compr

Dalton’s law of partial pressures applies equally to birds and mammals so, as gas moves from the nostrils to the smallest gas-diffusion airways, the sequential addition of water vapour and CO2, steadily reduce the partial pressure of O2 (PO2) withi

Transport of oxygen is one of the most important functions of blood. How oxygen moves from the air, where its partial pressure is about 150 mm Hg to mitochondria, where it drops down to a single digit is an evolutionary marvel. In this article, we di

Oxygen therapy is one of the most common forms of treatment in patients with respiratory distress. The main purpose of oxygen therapy is to increase alveolar oxygen tension and increase oxygen diffusion. This may be achieved by traditional oxygen del

Purpose This study tested the ability of a multibreath hyperpolarized HP 3He MRI protocol to increase the accuracy of regional alveolar oxygen tension (PAO2) measurements by lessening the influence of gas-flow artifacts. Conventional single-breath PA

Background: A non-invasive means of measuring pulmonary blood flow (PBF) would have numerous benefits in medicine. Tradition ally, respiratory-based methods require breathing maneuvers, partial rebreathing, or foreign gas mixing because exhaled CO2 v
