A 230-volt incandescent light bulb, with a 'medium' sized E27 (Edison 27 mm) male screw base. The filament is visible as the horizontal line between the vertical supply wires. SEM image of a tungsten filament of incandescent light bulb. An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to a high temperature, by passing an electric current through it, until it glows with visible light (incandescence).
Cord blood gases are typically drawn from the umbilicus during delivery to document oxygenation status of the newborn during delivery. Acidosis (pH less than 7.1 in an arterial cord blood gas) may indicate blood flow and hence oxygenation from mother to newborn may have been occluded during delivery. The Umbilical Artery is where the baby's venous circulation dumps unoxygenated blood. This is blood that was on its way back to the mom's heart and lungs to pick up oxygen.
Collection: Arterial punctures must be performed by qualified personnel. Prior to radial artery sampling, a test for collateral circulation should be performed and documented. Once the puncture has been performed or the arterial line specimen drawn, immediately remove all air from the syringe. Remove the needle, cap tightly and gently mix. Forward the specimen promptly at ambient temperature. Note on arterial line draws: The IV solution must be removed from the system prior to collection to prevent contamination. Special Processing: Lab Staff: Deliver the specimen to the blood gas testing station.
