Introduction You have probably opened a soda before and had the liquid fizz right up out of the bottle, creating a huge mess. The, lower portion of the dual tapered flow tube has a fine, taper for measuring low flows and the upper portion. PowerPoint Presentation: 53 ROTATORY STYLE KNOB: F low control knob for O 2 must have fluted profile. Authors: Jan Höller, Vlasios Tsiatsis, ... David Boyle. On anaesthetic machines [Figure 1] with a regulated, pressures of 45-60 PSIG there may be a relief valve, also called as pop off valve which opens at a pressure, to the vapourisers and flow meters if the outlet is, The pressure regulators and the intermediate pressure, circuits are concealed by a metal top for keeping drugs, and equipments like Laryngoscope and Endotracheal, tubes. improve patient safety and user convenience. many years anaesthesiologists did not require a machine to deliver anaesthesia to the patients. All the subsequent changes which have been brought are mainly to improve the safety of, the patients. The bobbin floats freely in the tube at an equilibrium, position where the downward force on it due to, gravity equals the upward force due to the gas flow, The gas flows in the annular opening between the, bobbin and the tube. Anaesthetic machines have additional regulators and check valves to those shown above. Boyle’s Law is important for us to understand how gases behave under pressure. Boyle’s law, a relation concerning the compression and expansion of a gas at constant temperature. After the introduction of oxygen and nitrous oxide in the form of compressed gases in cylinders, there was a necessity for mounting these cylinders on a metal frame. The, control knob is colour coded and touch coded for each, gas. The smallest V(T) and V(E) were produced using the Ohmeda Modulus II Plus anesthesia machine. Placing a cylinder in a yoke – cylinder valve and yoke should not be contaminated with oil/grease Yoke checked to make certain that two pin index safety system pins are present. Rotating indicators ( rotameters ) have upper rim ,diameter of which is larger than body. These are the devices which reduce the high pressures, in the cylinders to a lower and more constant pressure, to maintain a constant flow [Figure 3]. Branch: ......................................
