    May 31, 2016 · FIGURE 15-3 Check valve in the pipeline gas supply inlet at the back of the anesthesia gas machine. Gas enters from the supply hose at “Inlet” and proceeds (downwards in the illustration) into the machine . The right panel shows that gas cannot leak out of the machine if the supply hose is disconnected.

  • Where does the oxygen in anesthesia machine come from?

    The hospital medical gas pipeline source is the primary source for the anesthesia gas machine. Oxygen is produced by fractional distillation of liquid air.

  • What is the back check valve on an anesthesia machine?

    As gas enters the machine, there is a back-check valve that keeps gas flowing only one way into the machine. If the machine has two O 2 tanks and both valves are open, the back-check valves prevent the equalization of pressure between the tanks (gas flowing from a full tank into an empty tank).

  • What do you need to know about anesthesia gas machine?

    It must have a check valve to prevent transfilling, and a cylinder pressure gauge. There must be cylinder pressure regulators. The machine must use pipeline gas as long as pipeline pressure is greater than 345 kPa (50 psi). Flowmeters: Single control for each gas Each flow control next to a flow indicator Uniquely shaped oxygen flow control knob

  • Where do you find information on anesthesia machines?

    We will trace it from the gas supplies through the flowmeters, the vaporizers, the ventilator, and the breathing circuit to the patient and out through the waste gas scavenging system ( Fig. 26.1 ). As an anesthesia technician, you need to know where you can get information about the machines your institution uses.

  • Understanding the anesthesia machine - Shoal Creek

    Understanding the Anesthesia Machine The function of an anesthesia machine is to deliver oxygen (O2) and anesthetic gases, remove carbon dioxide (CO2) from the breathing system and provide controlled ventilation. Understanding the functions of the anesthesia machine is essential to ensure proper use. Most veterinary clinics use compressed gas ...

  • Anesthesia Gas Machine- Components and systems- Introduction

    The anesthesia gas machine is also called the anesthesia workstation, or anesthesia delivery system. The components and systems as described in this document are typical for a anesthesia gas machine. The differences between older gas machines (Ohmeda Modulus, Excel, ADU, or Aestiva and the Dräger Narkomed GS, Mobile, MRI, 2B, 2C, 3 or 4) are ...
