SunMed Percent-O2-Lock Oxygen Entrainment Systems

When a patient needs a precise, reliable fraction of inspired oxygen, guesswork isn't an option. The SunMed Percent-O2-Lock system delivers controlled FiO₂ through the venturi principle, drawing in a fixed ratio of room air to oxygen so respiratory therapists and clinicians can dial in the concentration a patient's condition actually calls for. This collection brings together the entrainment assemblies, masks, and kits that make that possible.

The heart of the system is the color-coded air entrainment mechanism. The SunMed Percent O2 Lock Air Entrapment Assembly (8057-0-50) and the latex-free Percent-O2-Lock Entrainment Assembly Without Masks (8058-7-50) let facilities pair the entrainment hardware with their preferred masks or existing stock, while the Percent-O2-Lock Oxygen Entrainment Masks Kit (8150-7-50) arrives ready to use with masks included. Each is engineered so the locking connection holds the selected oxygen percentage steady, even as flow demands shift.

Two questions come up most often. First, which version do I need? If your unit already stocks compatible masks, the assembly-only options keep costs down; if you want a complete, ready-to-hang setup, the masks kit is the straightforward choice. Second, is it latex-safe? The 8058-7-50 and 8150-7-50 are not made with natural rubber latex, an important detail for patients and staff with sensitivities. All are sold in case quantities of 50, which suits hospital respiratory departments, surgical centers, and EMS supply rooms restocking in volume.

Because venturi masks deliver a known, consistent concentration rather than the variable output of simple face masks, they're a mainstay for COPD patients and anyone requiring careful oxygen titration.
