Study Notes
Anesthesia Machine
- The anesthesia machine uses an iron box with two vacuum cleaners to create rhythmic negative pressure in the chest.
- This negative pressure inflates the lungs with air during inspiration, mimicking natural breathing.
- Expiration follows naturally.
- Anesthesia machines typically include a ventilator, vaporizers, humidifiers, CO2 absorbers, and other functionalities.
- Modern machines include patient safety features, such as monitors for heart rate, ECG, blood pressure, and oxygen saturation.
Gas Supply
- The hospital central medical gas pipeline is the primary source for anesthesia gas machines.
- Nitrous oxide is stored as a liquid in large tanks (745 psig - H tank).
- These tanks are connected to a manifold that regulates pipeline pressure to approximately 50 psig.
- Psig stands for pounds per square inch gauge.
- Cylinders (type E, G, or H) can also supply gas.
- Type E cylinders, commonly attached to the back of the anesthesia machine, contain 625 L of oxygen.
- G cylinders hold 5,300 L when full.
- H cylinders hold 6,900 L when full.
Cylinder Color
- The World Health Organization designates white as the color for oxygen cylinders.
