GENERAL DESCRIPTION GENERAL DESCRIPTION
The CROSSVENT-3+ Intensive Care/Transport Ventilator is an ultra compact, electronically controlled,
time cycled, volume or pressure limited ventilator with intensive care capabilities. It provides a wide range
of operating parameters to allow ventilatory support of patients from pediatric through adult.
CROSSVENT-3+ delivers the same oxygen concentration as the supply gas unless the optional entrainment
is in use in which case it is a nominal 50% O
The ventilator's microprocessors provide all operational functions, as well as monitoring the patient and
providing alarms. It allows the user to enter many different operational and alarm parameters to
accommodate a wide variety of clinical situations.
Airway pressure is sensed using an internal pressure transducer, and pressure is displayed as a bar graph on
the LCD. The patient inspiratory effort is also sensed using a pressure transducer. An absolute pressure
transducer monitors atmospheric pressure and automatically compensates the displayed flow for altitude
changes.
Since the CROSSVENT-3+ is totally separable from a compressor and since it may be used with any 31 to
75 psi (214 – 517 kPa) psi gas source, it is extremely versatile. It may be used in most areas of the hospital
and in transport. It may be mounted on a compressor, on a pedestal stand, a cart, a wall bracket, or a bed
rail. It may also be mounted in vehicles such as helicopters and ambulances.
CAUTION: Do not use in a MRI room.
The CROSSVENT-3+ has an internal battery which provides power during transport and in the event of an
AC power failure. If the external power should fail, the ventilator automatically switches to its internal
battery and sounds an alarm. The battery operation is approximately 6 hours on a fully charged battery. If
more time than that is required, the backlight may be turned off as described in this manual. Whenever
external power is restored, the CROSSVENT-3+ switches back to external power operation. It will charge
the battery whenever external power is available.
The CROSSVENT-3+ Ventilator's extreme reliability is made possible by:
• An absolute minimum of moving parts.
• An extremely low total parts count.
In addition to increased patient safety, the high reliability insures low downtime and thus more economical
use.
The CROSSVENT-3+ provides a complete array of features and ventilatory modes and functions which
include:
• Microprocessors control of all operational functions and monitoring.
• A Graphic LCD (liquid crystal display) with a touchscreen keypad, allowing the clinician to select
functions just by pressing the function displayed by the LCD. This provides the friendliest and
most flexible possible user interface.
• Automatic switch-over to battery backup operation.
• Auto-test mode with complete microprocessor diagnostics.
• Sensors to measure airway pressure, oxygen concentration (optional).
• Exhaled Tidal Volume and Minute Volume displays & alarms (optional).
• Displays and alarms for Peak Pressure, Rate, Mean Pressure, PEEP Pressure and Oxygen
concentration and more.
• Programmability and expandability.
• Built-in triggered demand flow for minimum work of breathing during SIMV and CPAP and a
simplified system design.
• Integral ASSIST CONTROL, SIMV, CPAP, PEEP, and Pressure Support functions.
• Altitude Compensation
• RS-232 input for PC interface for software updates.
