Lung volumes were measured using helium dilution. RESULTS: 15,838 PFTs were collected on individuals ranging from 17-74 years of age. 9,356 of these PFTs contained lung volume measurements. 10,144 contained diffusion capacity (DLCO) determinations. 3,469 lung volume and 3,936 DLCO measurements...

Explain the relationship between lung volume and lung capacity. Fill in the blanks: During acute high altitude exposures, oxygen diffusion across the alveolar-capillary membrane is ___ and this results in an ___ alveolar-arterial oxygen ...
Furthermore, airway closures induced by surfactant depletion compromises CO2 diffusion into the airspaces, which may explain the improved correlation and closer agreement between ELV and the other lung volume variables in the present of diminished surfactant function. These considerations highlight the ...
There are many causes of low oxygen saturation: various lung diseases can lead to too little oxygen reaching the pulmonary alveoli (ventilation disorder). Diffusion disorders are also possible, in which the gas exchange between alveoli and capillaries is disturbed. In addition, diseases of the blood...
Vital capacity d. Total lung capacity e. Expiratory reserve Under normal circumstances, the diffusion of oxygen is: a. perfusion limited. b. diffusion limited. c. neither perfusion limited nor diffusion limited. The ___ returns blood from head, ...

the transmural direction was obtained using the Curvilinear Coordinate interface and the diffusion method, which solves the Laplace equation (Eq.1) for the specified inlet (\(\:U=1\)at the endocardium boundary surface) and outlet (\(\:U=0\)at the epicardium boundary surface) boundary condition...
(c) assessment of the diffusion of small tracer molecules18. Due to the key function of the ion channel CFTR in airway fluid homeostasis and therefore, mucociliary clearance, assessment of its function will also further enhance our knowledge of the primary 3D airway epitheliumin vitromodel19,20...
How can you measure maximal anaerobic capacity? Fill in the blank: Body temperature below the normal range is called. What is the significance of lung elasticity to exhalation? Would you classify the alteration in normal lung function as a disorder of ventilation or...
