2.3 7100 ventilator components
Major components of the 7100 ventilator are found in different locations of
the anesthesia machine. These components, in general, serve identical
functions in either machine; however, since some components have minor
differences and are not interchangeable, they are named differently.
The ventilator package consists of:
1. a Control Module (CM) — which is identical for both machines.
The CM includes:
• a Control Board (CB)
• an LCD Display
• a Keyboard (with rotary encoder switch)
• a Power Supply
• a backup battery
2. a Monitoring Interface Assembly (MIA) in an Aestiva machine
or a Ventilator Monitoring Board (VMB) in an Aespire machine.
3. a Serial Adapter Board (SAB) in an Aestiva machine
or a Serial Isolation Connector Board (SICB) in an Aespire machine.
4. a Pneumatic Engine (PE) with Pneumatic Engine Board (PEB) in an Aes-
tiva machine or a Vent Engine (VE) with a Vent Engine Board (VEB) in
an Aespire machine.
