Refurbished - Datex Ohmeda 3800 Pulse Oximeter

The 3800 Pulse Oximeter has an easy-to-use interface and intuitive feature set, as well as advanced TruTrak® + technology, a proprietary clinical motion algorithm.

Features:

• TruTrak+ technology -- a proprietary clinical motion algorithm which identifies, quantifies and corrects clinical patient motion
• Always-visible Relative Perfusion Index™  (PI_r) -- a quick numeric value indicating pulse strength
• Plethysmographic waveform reinforces clinical decisions
• Backlit, always-on screen illuminate large numbers for fast recognition of readings
• Dedicated function keys and an always visible, simple menu system with no hidden functions
• Continuously displayed alarm limits for decisions at-a-glance
• Exceeds international durability standards through rigorous stress testing during design and manufacturing processes
• Full compatibility with all patient types and clinical situations using OxyTip®+ sensors and cables
