Red Orange Yellow Mixtures Of Pigments Color
582 wordsThe color wheel taught to most people today is the twelve-hue color circle developed by the Swiss color scientist, Johannes Itten. This color wheel is based on three mixtures of pigments, or a triad mixture, with red, yellow, and blue as the primary triad. All hues are formed from mixtures of equal or unequal amounts of primaries. Equal mixtures of two primaries result in the secondary hues and form the triad of green, orange, and violet. In this color wheel, six intermediate hues are created by...

Blood Loss O 2
1,574 wordsIntra-anesthesia hypoxia may be due to a problem with the anesthesia delivery system or a problem within the patient. The following are possible causes of hypoxia. A low supply of oxygen may be due to an inadequate FiO 2 mixture. If the proportioning system fails to allow a proper ratio of N 2 O to O 2 (3: 1) then a hypoxic mixture will be delivered. A bobbin in the flowmeter that is stuck can fool the anesthetist into believing that more O 2 is being delivered than in actuality. A depleted O 2 ...
