Why the study?
Does a multiple-breath analysis of diffusing capacity detect static pulmonary blood in patients with pulmonary vascular obstruction or hemorrhage?
Does a multiple-breath analysis of diffusing capacity detect static pulmonary blood in patients with pulmonary vascular obstruction or hemorrhage?
A novel multiple-breath DLCO analysis can detect static pulmonary blood, demonstrating sequential decreases in DLCO in patients with pulmonary vascular obstruction or hemorrhage.
No takes yet. Share an insight, caveat, or question.
May detect static pulmonary blood via sequential DLCO decline in obstruction or hemorrhage; hypothesis-generating and requires prospective validation.
Hallenborg et al. (1979) studied this question.
