Puritan Bannett 840

The Puritan Bennett 840 (PB 840) is a premium, high-performance critical care ventilator engineered to deliver exceptionally reliable respiratory support. Recognized globally as an industry workhorse for high-acuity intensive care units, it safely accommodates the entire patient spectrum, from fragile neonates and pediatric cases to adult patients. The system balances a highly responsive pneumatic design with dual-microprocessor architecture to ensure rapid breath delivery and maximum patient safety.

The ventilator is built with a modular, dual-console design featuring the DualView LCD touch screen system. This unique setup splits information onto two separate screens—the upper screen displays real-time monitoring data and waveforms, while the lower screen handles control settings and parameters—providing clinical teams with excellent visual scannability at the bedside.

Key Clinical Advantages

• Dual-Microprocessor Safety Architecture: Outfitted with an advanced internal control system powered by two independent microprocessors. One processor focuses entirely on breath delivery and patient triggering, while the second dedicated processor monitors safety loops and clinical data, ensuring constant cross-checking.
• Proportional Assist Ventilation (PAV+): Features an advanced, patient-controlled software mode that tracks the patient's real-time breathing effort. It measures work of breathing breath-by-breath, automatically supplying proportional support to match the patient's demand and ease weaning.
• Volume Proportionate Breath Delivery: Includes Volume Control Plus (VC+) technology, which combines the safety of volume targeting with the physiological comfort of pressure-controlled breathing. The system automatically adapts to changes in lung compliance to deliver the target breath using the lowest possible airway pressure.
• NeoMode Specialized Infant Software: Can be expanded with a high-precision neonatal module to safely support infants down to a very low body weight. This software optimizes flow sensitivity, adjusts circuit compliance compensation, and delivers precise, low tidal volumes.
• High-Performance Flow Sensitivity: Utilizes the advanced Flow-i triggering mechanism, which detects the exact moment a patient initiates a breath. This rapid response time minimizes the physical work of breathing and reduces patient-ventilator asynchronous fighting.
• Tube Compensation Weaning Tool: Equipped with software that calculates and continuously offsets the extra physical resistance imposed by an endotracheal or tracheostomy tube, simulating a virtual extubation environment to assess a patient's true breathing capability.
• Leak-Compensated Non-Invasive Ventilation (NIV): Offers high-precision mask ventilation modes featuring advanced leakage compensation software. This ensures accurate volume delivery, maintains precise trigger levels, and prevents accidental alarms during high-leak scenarios.
• Uninterrupted Expiratory Valve Design: Engineered with a specialized, active exhalation valve that allows completely unrestricted breathing during any part of the breath cycle. This open design lowers peak airway pressures and improves overall patient comfort.
• One-Touch Pre-Oxygenation Protocol: Built with a dedicated standby function that allows clinicians to deliver high-concentration oxygen for a set timeframe before and after airway suctioning procedures, preventing sudden oxygen drops.
• Highly Modular Component Setup: Designed with a separable breath-delivery unit and display screen. This flexible architecture allows the ventilator components to be mounted on a rolling trolley frame, a heavy-duty wall bracket, or an overhead intensive care service column.
• Robust Backup Power Solution: Supported by an integrated Backup Power Source (BPS) battery module that automatically assumes operations if the main electrical supply fails, securing uninterrupted mechanical ventilation for extended periods.
