Mini Oxygen Regulator (Click Style, 0–15 LPM, Barb Outlet, CGA-870) by Drive™ DeVilbiss Healthcare

Drive DeVilbiss Healthcare’s Mini Oxygen Regulator (0–15 LPM, CGA-870) provides precise, reliable control of supplemental oxygen flow for patients requiring respiratory support. This compact, medical-grade regulator attaches to any standard CGA-870 oxygen cylinder (D or E size) and features an intuitive click-style flow knob that adjusts in clear 1 LPM increments (including an OFF position). Each “click” corresponds to a specific flow rate, so patients and caregivers can set exact oxygen delivery with confidence. The regulator’s aluminum alloy body houses precision brass internals and is cleaned for oxygen service, ensuring clean, safe oxygen output. It also includes a built-in pressure gauge and pressure-relief valve for safety, allowing users to monitor tank levels and preventing over-pressurization during therapy.

Ideal for respiratory care, this regulator is widely used in oxygen therapy to help ease breathing and improve lung health. It is commonly prescribed for people with chronic lung conditions (such as COPD, asthma, bronchitis or emphysema) or recovering from pneumonia, where controlled oxygen flow can relieve shortness of breath and maintain healthy blood oxygen saturation. By delivering supplemental oxygen at a steady, accurate rate, it supports pulmonary function and promotes better overall health. Lightweight and compact (about 4 inches long and 0.7 lbs), the mini design fits easily into portable oxygen packs, ambulances, or home-care settings. Its direct barb outlet connects quickly to nasal cannulas or oxygen masks, making set-up fast and foolproof. Whether used in hospitals, clinics, home healthcare, emergency kits or even high-altitude activities, the Drive DeVilbiss regulator ensures a patient-friendly oxygen supply that clinicians trust.

Key Features

• Precise Click-Style Flow Control: Adjustable from 0 to 15 LPM, the single-knob “click” dial provides exact control over oxygen flow. Each clearly marked liter-per-minute setting produces an audible click, so staff can set the flow rate by feel or sight without guesswork. This precision is vital for tailoring oxygen therapy to patient needs (e.g. setting 2 LPM for mild hypoxia or up to 15 LPM for acute respiratory distress).

• Built-In Safety Mechanisms: To protect patients, the regulator includes a pressure-relief valve and a transparent contents gauge. These features prevent dangerous over-pressurization and let users monitor cylinder pressure at a glance. Health practitioners rely on these safety measures to avoid hypoxia or oxygen starvation; the gauge indicates when a cylinder is nearly empty so it can be replaced in time, ensuring continuous oxygenation.

• Medical-Grade Construction: Engineered for durability and purity, the regulator has an aluminum outer body with brass internal components. All parts are machined (not cast) and oxygen-clean, meaning the regulator is free of lubricants or contaminants. The rugged metal design stands up to daily use in home or clinical settings without wear, and the green finish makes it easy to identify (green is industry-standard for 0–15 LPM high-flow oxygen regulators).

• Direct Oxygen Delivery: Equipped with a 1/4″ barb outlet, the regulator connects directly to standard oxygen tubing, nasal cannulas or masks. Because there’s no need for adapters or intermediate fittings, the setup is quick and reliable — perfect for emergency response or routine care. The CGA-870 inlet fits common oxygen cylinders used in hospitals and ambulances, so this one regulator works wherever an oxygen tank is used.

• Compliance & Warranty: This Drive DeVilbiss regulator meets/exceeds all ASTM, ANSI and CGA standards for accuracy and safety. It is UL® listed and comes backed by a three-year warranty, reflecting the manufacturer’s confidence in quality. Such compliance assures medical professionals that every unit delivers the consistent, exact performance needed for regulated oxygen therapy.

Health Benefits and Applications

This Mini Oxygen Regulator supports a wide range of health needs by enabling safe, controlled oxygen therapy:

• Improves Respiratory Health: Delivering correctly-metered oxygen can significantly help patients with chronic obstructive pulmonary disease (COPD), chronic bronchitis, asthma, pulmonary fibrosis or emphysema. By easing hypoxia, it reduces shortness of breath, enhances exercise tolerance, and can improve oxygen saturation in the blood. Better oxygenation also supports tissue healing and overall vitality.

• Enhances Medical Treatment: In acute care or emergencies (such as pneumonia, acute asthma attacks or post-surgical recovery), accurate oxygen flow control is life-saving. This regulator lets healthcare providers fine-tune oxygen therapy to patient condition, ensuring neither too little nor too much oxygen is given. Stable oxygen delivery can decrease strain on the heart and lungs, speeding recovery and preventing complications like organ stress.

• Supports Athletic and Altitude Use: Athletes and climbers at high elevation sometimes use supplemental oxygen to boost performance and endurance. The Drive DeVilbiss regulator’s compact, lightweight design makes it suitable for mobile oxygen kits. It provides steady oxygen support that can help reduce fatigue and improve physical stamina when oxygen levels drop at altitude or during intense exercise.

• Home Oxygen Therapy: Many individuals live healthier, more active lives with daily oxygen therapy at home. This regulator easily attaches to oxygen cylinders in home care, senior living facilities or ambulatory clinics. Patients with respiratory diseases or heart conditions benefit from consistent oxygen during sleep and daily activities, improving sleep quality, appetite and concentration.

• Emergency and Travel Preparedness: Paramedics, EMTs and safety officers keep this regulator on hand to manage oxygen cylinders in ambulances or emergency kits. Its quick-connect barb outlet and intuitive knob make it ideal for urgent situations. Outdoor enthusiasts and travelers can also use it with portable oxygen tanks to handle sudden breathing difficulties or altitude sickness.

By ensuring safe, precise oxygen delivery, the Drive DeVilbiss Mini Regulator plays a vital role in respiratory care and pulmonary health, helping users breathe easier and maintain active lifestyles.

Safety and Usage Notes

• Medical Use Only: This regulator is intended for use with medical oxygen under a doctor’s prescription or professional supervision. Always follow healthcare provider instructions.
• Operation: Turn the flow knob to OFF before opening the cylinder valve. After opening the valve fully, set the desired flow rate by turning the knob until you feel each click. Check the gauge to ensure adequate tank pressure.
• Oxygen Delivery Devices: Designed for use with approved oxygen masks, nasal cannulas, or BVMs (bag-valve masks). Verify tubing is properly attached to the barb outlet to prevent leaks.
• Safety Precautions: Keep oxygen equipment away from open flames or heat sources. Do not use oil, grease or flammable substances on or near the regulator. Store and transport cylinders upright and secure at all times.
