Introduction
The 700 Series Ventilator System (including the 740 and 760
Ventilators) provides respiratory support for a wide range of
pediatric to adult patients for a wide variety of clinical conditions.
The ventilator’s mixing technique allows it to ventilate critically ill
patients at adjustable oxygen concentrations without the need for a
blender, compressor, or hospital-grade wall air.
The 700 Series Ventilator System can be mains- or battery-powered.
Each ventilator includes two microcontrollers: one for breath delivery
(which controls ventilation), and one for the user interface (which
monitors ventilator and patient data). Each microcontroller verifies that
the other is functioning properly. Using two independent
microcontrollers in this fashion prevents a single fault from causing a
simultaneous failure of controlling and monitoring functions.
The 700 Series Ventilator System supplies mandatory or spontaneous
breaths with a piston-based pneumatic system. Table 1-1 summarizes
the modes and breath types offered by the 740 and 760 Ventilators.
Mandatory breaths can be volume control ventilation (VCV, available
on 740 and 760 Ventilators) or pressure control ventilation (PCV,
available on the 760 Ventilator only). VCV delivers breaths to the
patient at a preset tidal volume, peak flow, waveform, and oxygen
concentration at a minimum respiratory rate. PCV delivers breaths to
