STUDY OBJECTIVES To determine if 100% oxygen administration adversely influences gas exchange in acutely ill asthmatic subjects. DESIGN Prospective preinterventional and postinterventional comparison. SETTING University hospital emergency department. PATIENTS Thirty-seven asthmatic subjects seeking care for symptomatic exacerbations. INTERVENTIONS Twenty minutes of 100% oxygen administr...
AIM To investigate the influence of acute changes in intraocular pressure on the oxygen tension in the vicinity of the optic nerve head under control conditions and after intravenous administration of 500 mg of the carbonic anhydrase inhibitor dorzolamide. METHODS Domestic pigs were used as experimental animals. Oxygen tension was measured by means of a polarographic electrode in the vitreous...
PURPOSE OF REVIEW Clinical practices in oxygen administration are in need of change based on the increasing understanding of oxygen toxicity. Hypoxemia is due to many pathophysiological causes; avoiding hypoxemia is an important objective during neonatal anesthesia. Nevertheless, the only known cause for hyperoxemia is the excess and unnecessary administration of oxygen by healthcare providers....
This study was performed to test the hypothesis that administration of recombinant human erythropoietin (rHuEpo) in humans increases maximal oxygen consumption by augmenting the maximal oxygen carrying capacity of blood. Systemic and leg oxygen delivery and oxygen uptake were studied during exercise in eight subjects before and after 13 wk of rHuEpo treatment and after isovolemic hemodilution t...
