A range of stationary and portable devices that filter and concentrate oxygen from ambient air. This category also includes the essential accessories—such as cannulas, masks, and tubing—required to safely deliver oxygen therapy to patients in clinical or home settings

Air & Oxygen Blender

An Air & Oxygen Blender is a Class II medical device that precisely mixes compressed medical air and oxygen to deliver controlled fractions of inspired oxygen (FiO2 21-100%) to patients requiring respiratory support. Essential in neonatal, pediatric, and adult critical care, these devices ensure accurate oxygen delivery via ventilators, CPAP systems, oxygen hoods, incubators, and transport systems. Operating at 40-60 psi inlet pressure, they maintain set FiO2 within ±2-5% accuracy across varying flow demands (0-120 L/min). Gas-specific DISS or NIST fittings prevent dangerous cross-connection between oxygen and air supplies. Available in wall-mounted, rail-mounted, portable, and ventilator-integrated configurations. Primary clinical applications include neonatal intensive care (oxygen hoods, incubators, nasal CPAP), pediatric and adult mechanical ventilation, non-invasive ventilation, and critical care transport. Critical safety requirements include verification of correct gas connections, regular calibration, leak testing, and immediate response to gas supply failure alarms. Indispensable for preventing both hypoxemia and oxygen toxicity (particularly retinopathy of prematurity in neonates) in patients requiring precise oxygen therapy.

Humidifier Bottle

A Humidifier Bottle is a water reservoir device that adds moisture to dry medical oxygen before delivery to the patient. It attaches between the oxygen flow meter and the patient's oxygen delivery device, bubbling oxygen through sterile water to achieve relative humidity levels of 80-95%. Essential for patients receiving oxygen at flow rates above 4-6 liters per minute, it prevents drying of the nasal mucosa, pharynx, and lower airways, reducing discomfort and maintaining normal mucociliary clearance. Available in disposable sterile and reusable configurations, the bottle requires daily water changes with sterile water and proper positioning below the patient to prevent water carryover. Pressure relief valves protect against over-pressurization.

Infant Oxygen Hood

An Infant Oxygen Hood is a Class II medical device used to deliver controlled concentrations of supplemental oxygen to spontaneously breathing newborns and infants. Made of transparent medical-grade acrylic or polycarbonate, the hood fits over the infant's head with a soft foam or rubber neck seal, creating an oxygen-enriched environment while allowing easy access for monitoring and care. Available in premature/neonatal, infant, and older infant sizes with gas inlet ports (22 mm) for connection to air/oxygen blenders (FiO2 21-100%), access ports for monitoring leads and IV lines, and outlet vents to prevent CO2 accumulation. Requires minimum flow rate of 5 L/min to ensure adequate CO2 washout. Used with heated humidifiers for prolonged therapy to prevent airway drying. Primary clinical applications include management of respiratory distress syndrome (RDS) in premature infants, neonatal pneumonia, post-extubation oxygen support, congenital heart disease, and palliative care. Critical safety considerations include maintaining adequate flow rate to prevent rebreathing, monitoring FiO2 at hood level, ensuring proper neck seal without constriction, and preventing hyperoxia to reduce retinopathy of prematurity (ROP) risk. Essential equipment in NICUs and special care nurseries for controlled oxygen delivery to vulnerable infants.

Non-Rebreathing Oxygen Mask

 An  Non-Rebreathing Oxygen Mask is a high-concentration oxygen delivery device designed for emergency use in critically hypoxic patients. It features a face mask with an attached reservoir bag and a system of one-way valves to prevent the rebreathing of exhaled carbon dioxide, allowing for the delivery of up to 95% FiO2. Its safe operation depends on a minimum oxygen flow of 10-15 L/min to keep the reservoir bag inflated. It is contraindicated where uncontrolled high-flow oxygen may be harmful (e.g., in some COPD patients) and carries a severe fire risk. It is a vital, immediate-intervention tool found in all emergency response settings.

Oxygen Concentrator

An Oxygen Concentrator is a Class II medical device that delivers 90-95% pure supplemental oxygen to patients with chronic hypoxemia using pressure swing adsorption (PSA) technology to concentrate oxygen from room air. Available as stationary/home units (10-30 kg, 0.5-10 L/min continuous flow) for long-term oxygen therapy (LTOT) and portable/ambulatory units (1-10 kg, 0.5-3 L/min pulse-dose or continuous flow) for active patients requiring mobility. Features include oxygen purity monitoring with alarms, digital flow control, hour meters, washable filters, and (for portable units) rechargeable batteries, FAA approval for travel, and pulse-dose delivery to conserve oxygen. Primary clinical indications include COPD, pulmonary fibrosis, cystic fibrosis, and other chronic respiratory conditions with resting, exertional, or nocturnal hypoxemia (PaO2 ≤55 mmHg or SpO2 ≤88%). Essential for home-based oxygen therapy, enabling patients to maintain independence, reduce hospitalizations, and improve quality of life. Critical safety precautions include NO SMOKING in the oxygen environment, keeping away from heat sources and open flames, proper electrical safety, regular filter cleaning, and having backup oxygen for power outages.

Oxygen Mask (Adult/Infant/Paediatric)

 An Oxygen Mask is a disposable, single-use interface used to deliver supplemental oxygen from a medical gas supply to a patient's airways. Available in types for specific clinical needs—Simple Mask for low-flow therapy, Venturi Mask for precise FiO2 control (especially in COPD), and Non-Rebreather Mask for emergency high-flow delivery—and in sizes for adults, children, and infants. Correct selection and application, including ensuring the proper oxygen flow rate for the mask type, are essential for effective therapy and patient safety. Adherence to strict fire safety protocols is non-negotiable due to the combustion risk posed by enriched oxygen environments.

Oxygen Regulator Set

 An Oxygen Regulator Set is a critical pressure control device that attaches to a medical oxygen cylinder, reducing its extremely high internal pressure to a safe, usable level and providing precise control over the flow rate delivered to the patient. Consisting of a pin-indexed yoke, high-pressure gauge, adjustable flowmeter, and safety outlet, it is the essential interface for safe oxygen delivery from cylinders in emergencies, during transport, and in home care. Its safe operation hinges on absolute adherence to oil-free handling procedures, correct connection techniques, and regular inspection for leaks or damage to prevent catastrophic oxygen-fuelled fires or equipment failure.

Oxygen set (gauge, humidifier, flow meter)

An Oxygen Set consists of a pressure gauge, flow meter, and humidifier that together regulate, monitor, and humidify oxygen delivered to a patient. The pressure gauge indicates cylinder contents, the flow meter controls delivery rate in liters per minute, and the humidifier adds moisture to dry medical oxygen to prevent airway irritation. Used with wall outlets or portable cylinders, this equipment is essential for all oxygen therapy delivery. Safe operation requires strict adherence to no-oil, no-smoking policies, regular monitoring of water levels and cylinder pressure, and proper orientation of the flow meter for accurate delivery.

Portable Oxygen Concentrator

 A Portable Oxygen Concentrator (POC) is a lightweight, battery-powered device that delivers oxygen via pulse dose technology, enabling active, mobile lifestyles for patients with chronic lung disease. By providing oxygen on-demand with each breath, it maximizes battery efficiency and portability, allowing users to travel, exercise, and socialize freely. It is a prescription-only device that requires careful titration to match a patient's needs during activity and is not a substitute for a stationary concentrator used at home and during sleep. Key considerations include FAA approval for air travel, battery life management, and understanding its specific use case as an ambulatory aid, not a primary oxygen source.
