Puritan Bennett 840 Ventilator Operator Manual
ABOUT THE PURITAN BENNETT 840 Ventilator
The Puritan Bennett® 840™Ventilator System is the flagship product in our line of critical care ventilators. It is responsive to patients and offers superior comfort, delivering sensitive, precise breaths to critically ill neonatal through adult patients. Patient comfort: With highly responsive proportional solenoid valves, an active exhalation valve and state-of-the-art flow sensors, the 840 ventilator provides exceptional responsiveness and control. These features deliver sensitive and precise breaths, and in turn, superior comfort to patients. SmartAlert™ Alarm System: Prioritized alarm annunciation distinguishes primary alarms from secondary, “dependent” alarms. System indicates the urgency level of each alarm to help you efficiently respond to alarm conditions. Protection from contaminants: A special filter heating process shields patients and clinicians from exposure to viruses and bacteria from exhaled gases. Expiratory filter is capable of filtering viruses such as SARS. Circuit disconnect alarm: Special circuit disconnect alarm does not rely on low pressure or tidal volume to activate. When a circuit disconnects, gas flow stops to prevent the spread of contaminants. Technicians are alerted so they can quickly identify the source of the disconnection. Self-diagnostic testing: Subsystems are thoroughly checked 100 times per second. Message display notifies technicians of potential failures if any drift in performance occurs while ventilating. Seamless communication: The 840 ventilator supports communication with all major patient monitoring and hospital information systems. It also provides seamless recorded data transfer into a patient’s electronic medical record. Puritan Bennett Clinivision Mobile Patient Charting System: The 840 ventilator teams up with the Clinivision system to automate respiratory care patient charting and help balance RT workloads. The Clinivision system offers the latest in wireless, mobile clinical information technology, puts patient information right where you need it—at your fingertips, produces more accurate records and improved charge capture, and supports evidence-based medicine for improved patient care. Ease of use: The innovative design of the 840 ventilator makes it easy for technicians to set up and navigate. It minimizes training requirements for your staff. DualView™ LCD touchscreens display monitored data separately from ventilator settings, so clinicians can change settings and view the impact in one easy place. Short self-test feature resets the 840 ventilator settings in between patient use in about two minutes. The test checks for proper ventilation operation and calculates circuit compliance. Best in class service: Puritan Bennett offers one of the most comprehensive field service programs in the ventilator industry. Our extensive team of Customer Service Engineers and Technical Support staff are dedicated to giving Puritan Bennett ventilator customers the highest quality service.

Indications for Usage
For use in providing neonate through adult patients with ventilatory support in the hospital environment.
Software Options
PAV™+ Software – Provides consistent support for the work of breathing even with changes in respiratory drive.
BiLevel® Software — Allows patients to breathe spontaneously at two levels of PEEP, for greater patient/ventilator synchrony.
Volume Ventilation Plus™ Software — A pressure control breath style with a guaranteed tidal volume.
Tube Compensation Software — A spontaneous breath delivery enhancement that accurately overcomes the work of breathing through an artificial airway.
NeoMode® Software — Allows the 840 Ventilator to ventilate patients as small as 500 grams without requiring a flow sensor at the patient’s airway.
