7.1 Introduction
The A7 anesthesia system can be broken down into 18 big parts based on its structure and functions.
Each big part includes several replaceable parts. Table 9-1 through Table 9-17 list the information
about each replaceable part and Figure 9-1 through Figure 9-17 indicate the position of each
replaceable part on the A7. 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 card) are
faulty, replacing the card 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.
