Percent-O2-Lock Air Entrainment System – Venturi Oxygen Mask 24–50% FiO2

The Percent-O2-Lock Air Entrainment System is a Venturi-style oxygen delivery system designed to provide precise and controlled oxygen concentrations. Unlike standard masks, this system allows users to dial in and lock a specific oxygen percentage for consistent therapy.

This complete setup typically includes an air entrainment mask, adjustable Venturi valve, humidity cup, and oxygen tubing, making it ideal for clinical and home care environments where accurate oxygen delivery is required.

Quick Summary

• Venturi system delivers precise oxygen concentrations
• Adjustable FiO2 settings from 24% to 50%
• Locking mechanism maintains selected oxygen level
• Includes mask, tubing, and humidity cup (varies by kit)
• Designed for controlled oxygen therapy

Why Choose a Venturi Oxygen System?

Venturi (air entrainment) systems are used when precise oxygen delivery is critical. Instead of delivering variable oxygen like standard masks, they mix oxygen with room air to achieve a consistent, prescribed concentration.

The Percent-O2-Lock design includes a dial-and-lock feature, allowing clinicians and caregivers to set and maintain exact oxygen levels without fluctuation.

Key Specifications

• System Type: Venturi / Air Entrainment Oxygen System

• Situations where consistent FiO2 is required

Important Use Note

This system is intended for controlled oxygen delivery and should be used according to prescribed oxygen settings. It is different from standard oxygen masks and cannulas that deliver variable oxygen flow.
