Puritan Bennett 840 Ventilator Continuous Alarm

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.
