How to use this manual
The Aestiva comes with several user manuals. This manual describes the
controls and how to use them.
1-2
Section 1 shows the different models and supplies information about the symbols used on the equipment.
Section 2 shows control locations.
Section 3 tells you how to use the controls.
Section 4 is a two-page, preoperative checklist.
The appendix provides complete instructions for the preoperative tests shown on the checklist.
The Aestiva/5 7900 can be equipped with several optional ventilation functions. References made in this manual to Heliox mode, and SIMV and PSVPro modes, are only applicable to systems equipped with these functions.
Use this manual together with Part 2, which includes setup, troubleshooting, calibration, and maintenance procedures.
What is an Aestiva?
The Aestiva is a flexible, accessible and intuitive anesthesia delivery system. A wide selection of frames, gases, and vaporizers give you full control of the system configuration.
Options include pendant mounted systems, extra gas cylinders or vaporizers, and left or right-hand breathing systems.

Ventilators and monitors |
The system uses a microprocessor-controlled ventilator with internal monitors, |
|
electronic PEEP, multiple modes of ventilation, and a pressure waveform dis- |
|
play. Built-in connectors and communication software permit optional |
