BMC Pulmonary Medicine, 2018 Background The relationship of spirometric values to other respiratory and functional parameters in advanced age is not well studied. We assessed this relationship in elderly subjects with either good or poor spirometric parameters to reveal whether ...

Capacity of discrete molecular diffusion channels [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 In diffusion-based molecular communications, messages can be conveyed via the variation in the concentration of molecules in the medium. In this paper, we intend to analyze the achievable capacity in transmission of information from one node to another in a diffusion channel. We observe that because of the molecular diffusion in the medium, the channel

Spirometry, Static Lung Volumes, and Diffusing Capacity [PDF]
, 2017 BackgroundSpirometric Z-scores from the Global Lung Initiative (GLI) rigorously account for age-related changes in lung function and are thus age-appropriate when establishing spirometric impairments, including a restrictive pattern and air-flow ...

Regional diffusing capacity in normal lungs during a slow exhalation [PDF]
, 1982 From an analysis of carbon monoxide uptake and xenon-133 distribution after two bolus inhalations of these gases, we calculated regional diffusing capacity in the upper and lower volume halves of the lungs during the middle 60% of an exhaled vital ...

Lymphangioleiomyomatosis: circulating levels of FGF23 and pulmonary diffusion [PDF]
Jornal Brasileiro de Pneumologia, 2023 Objective: Lymphangioleiomyomatosis (LAM) is a rare, destructive disease of the lungs with a limited number of determinants of disease activity, which are a critical need for clinical trials.

Carrying Capacity of a Population Diffusing in a Heterogeneous Environment
Mathematics, 2020 The carrying capacity of the environment for a population is one of the key concepts in ecology and it is incorporated in the growth term of reaction-diffusion equations describing populations in space.

New insights into the aspects of pulmonary diffusing capacity in Fontan patients [PDF]
, 2014 BACKGROUND: Patients with a functionally univentricular heart, palliated a.m. Fontan, consequently have non-pulsatile pulmonary blood flow and are known to have a reduced pulmonary diffusing capacity. However, the cause of this reduction remains unclear.

Effects of exercise on thoracic blood volumes, lung fluid accumulation, and pulmonary diffusing capacity in heart failure with preserved ejection fraction [PDF]
, 2020 Patients with heart failure with preserved ejection fraction (HFpEF) experience symptoms of exertional dyspnea that may be related to lung fluid accumulation during exercise.

A modeling approach to the estimation of CO diffusing capacity [PDF]
, 1987 Standard methods of measuring the diffusing capacity of the lung for CO are susceptible to inhomogeneity and to errors in the performance of a breathing maneuver by the subject.
