7.1 Introduction
The A5/A3 anesthesia system can be broken down into 18 big parts based on its structure and
function. Each big part includes several replaceable parts. Tables 8-1 through 8-18 list the information
about each replaceable part and Figures 8-1 through 8-14 indicate the position of each replaceable
part on the A5/A3. The selection of replaceable parts gives consideration to the characteristics of the
parts, cost of replacement, and maintenance efficiency. When the parts whose sub components are
not convenient to replace (such as the electronic component on the board) are faulty, replacing the
board can improve the maintenance efficiency. For example, if a pressure gauge on the instrument
panel is faulty, replacing the pressure gauge can reduce the cost.
