15 صفحه اولCorneal swelling at low atmospheric oxygen pressures.
Corneas of 28 human subjects were exposed to oxygen partial pressures, in a gas goggle, of either 6.9, 17.1, or 22.2 mm Hg, and the corneal swelling was measured by pachometry for 4 hr. Following an initial rise, the swelling stabilized after about 3 hr; in many subjects it was reversed, indicating an adaptation process. The average corneal swelling after 4 hr for the three oxygen partial press...
متن کاملCorneal swelling at low atmospheric oxygen pressures
both cornea and conjunctiva occurred as early as 15 min after bacterial inoculation. By 1 to 3 hr after bacterial inoculation, shrinkage of corneal epithelial cells was pronounced (Fig. 5, a and b). Fewer microvilli were seen on the shrunken regions of these affected cells, and the cell surfaces appeared roughened and irregular. Additionally, intercellular junctions were dilated to 1.0 fim in d...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...
