The effects of fetal hypoxemia on renal hemodynamics and renal function were studied in two groups of chronically catheterized young (< 120 days of gestation) and near-term lamb fetuses (> 130 days). Fetal hypoxemia produced, in both groups, a significantly decrease in renal blood flow (RBF) and a significant increase in the filtration fraction. However, the glomerular filtration rate (GFR) did...

BACKGROUND In adequately resourced clinical environments, diagnosis of hypoxemia via pulse oximetry is routine. Unfortunately, pulse oximetry is rarely utilized in under-resourced hospitals in developing countries. AIM The prevalence of undiagnosed hypoxemia among adults and children with illnesses other than pneumonia in these environments remains poorly described. METHODS This cross-secti...

BACKGROUND Supplemental oxygen is routinely administered to patients with acute coronary syndromes. The risk of significant morbidity during cardiac catheterization or coronary angioplasty has been well described; however, to our knowledge, the need for routine oxygen supplementation in these patients has not been investigated. METHODS In phase 1, we prospectively studied 142 patients undergo...
