Medical Oxygen Cylinder with Regulator and Flow Meter in Bangladesh

When a patient struggles to breathe, minutes matter. A medical oxygen cylinder is the most dependable way to deliver oxygen at home, in a clinic, in an ambulance or at the bedside when a concentrator is not available or the power fails. Advanced Medical Equipment supplies portable medical oxygen cylinders in several sizes, supported by a pressure regulator with flow meter and an optional humidifier bottle, so that you receive a ready-to-use oxygen set rather than a bare steel bottle. This listing covers the Linde-type medical oxygen cylinder range shown in the product photo, from a compact cylinder for short-term or travel use to taller high-capacity cylinders for longer therapy.

What You Receive

A complete oxygen therapy set normally includes the following parts. Please confirm the exact configuration and cylinder size with our team when you order, because capacity, fittings and accessories can differ between units.

• Seamless steel cylinder with a white shoulder, which is the colour code used for medical oxygen cylinders, and a dark body.
• Cylinder valve with a hand wheel to open and close the gas supply.
• Pressure regulator with a gauge that shows how much pressure remains in the cylinder.
• Flow meter to set the oxygen flow rate in litres per minute as prescribed by the doctor.
• Humidifier bottle on the outlet, shown on two of the cylinders in the photo, to add moisture to the oxygen during longer use.
• Nasal cannula or oxygen mask and tubing, available as accessories.

Cylinder Capacity and How Long It Lasts

The duration of a cylinder depends on its water capacity, its fill pressure and the flow rate set on the flow meter. As a reference, published Bangladesh market reports have described a 1,400-litre cylinder lasting roughly ten to eleven hours at a flow of 2 litres per minute, and a Linde medical cylinder with 2,000 litres of oxygen being listed for continuous use at low flow. Divide the oxygen volume by the flow rate to estimate the time: a cylinder holding 1,400 litres at 2 L/min lasts about 700 minutes, which is just under twelve hours before accounting for the unusable pressure that stays in the cylinder. Always keep a spare cylinder or arrange a refill before the gauge drops near empty, especially for patients who depend on continuous oxygen.

Smaller cylinders are easier to carry and are useful for transport, emergency response and short procedures. Larger cylinders last longer and are better suited to bedside use. Ask us which size suits your patient and how often you will need refills.

Common Uses

Home oxygen therapy. Patients with chronic lung disease, severe asthma, pneumonia recovery or post-COVID breathing problems sometimes need supplemental oxygen at home, as prescribed by their doctor. A cylinder gives a silent, electricity-free source that can be started instantly.

Backup for oxygen concentrators. Concentrators depend on mains power. In areas with load-shedding, a cylinder is a sensible backup that protects the patient when power is lost.

Clinics and small hospitals. Emergency rooms, observation wards, day-care units and diagnostic centres keep cylinders ready for sudden respiratory distress, cardiac events and recovery from procedures.

Ambulances and patient transport. A portable cylinder with regulator allows oxygen to continue while moving a patient between facilities.

Dental and minor surgical settings. Practices that perform procedures under sedation commonly keep oxygen available as part of their safety equipment.

Safety Rules You Must Follow

Oxygen does not burn by itself, but it makes fire far more intense. Handle every cylinder with care.

• Never allow smoking, candles, gas stoves or open flames within several metres of oxygen equipment.
• Keep oil, grease, petroleum jelly, hand cream, aerosol sprays and alcohol-based products away from the valve, regulator and fittings. Do not apply lubricant to any connection.
• Store the cylinder upright and secured with a chain, strap or trolley so it cannot fall. A falling cylinder can damage the valve.
• Open the valve slowly using only your hand. Do not use tools unless the manufacturer says so.
• Close the valve fully when the cylinder is not in use and release the pressure in the regulator according to the instructions.
• Keep the cylinder away from heat sources, direct sunlight and heavy traffic areas.
• Use the flow rate prescribed by the doctor. Do not increase the oxygen flow on your own, particularly for patients with chronic lung disease.
• Check the hoses and connections for leaks before each use.

How to Start Oxygen Therapy with a Cylinder

First, place the cylinder upright on a stable surface or trolley. Remove the protective cap and check that the valve outlet is clean and dry. Fit the regulator onto the valve outlet and tighten it by hand as instructed. Fill the humidifier bottle with clean distilled or boiled and cooled water up to the marked level if your doctor advises humidification. Connect the tubing and cannula or mask. Open the cylinder valve slowly and read the pressure gauge. Turn the flow meter control until the ball or indicator rests at the prescribed litres per minute. Place the cannula or mask on the patient and confirm that oxygen is flowing. When you finish, close the cylinder valve, let the remaining gas bleed out through the flow meter, and then turn the flow control to zero.

Refilling and Maintenance

Oxygen cylinders are refillable. Refills must be done by an authorised oxygen supplier, never by the user. Inspect the cylinder for dents, rust or damage to the valve before every use, and check the test date stamped on the cylinder according to local regulation. Wipe the body with a damp cloth and keep the regulator clean and dry. If the gauge does not return to zero after closing the valve, or if you hear hissing, stop using the equipment and contact us.

The humidifier bottle should be emptied, washed and refilled with fresh water regularly to avoid bacterial growth. Replace cannulas and masks according to the manufacturer advice and whenever they become dirty or damaged.

Why Buy from Advanced Medical Equipment

Buying oxygen equipment is a decision that involves safety, so choose a supplier who answers questions properly. We help customers pick the right cylinder size, regulator and accessories, explain how to use them safely, and guide you on refilling. We also supply oxygen concentrators, nebulizers, pulse oximeters, humidifier bottles and hospital furniture, so you can equip a patient room from one place. Delivery is available throughout Bangladesh, and bulk supply is possible for hospitals, clinics and NGOs.

Frequently Asked Questions

Is the cylinder supplied filled? Please confirm the filling status when you order. Filling and refilling are handled through authorised oxygen suppliers and may be charged separately.

Can I use this without a doctor's advice? Oxygen is a medical gas. Use it for emergency support only as advised, and follow your doctor's prescription for flow rate and duration.

Do I need a humidifier? For low flow rates over short periods, many doctors do not require one. For longer therapy, a humidifier bottle can make breathing more comfortable. Ask your doctor.

Can I carry the cylinder in a car? Secure it upright, keep the valve closed, and ventilate the vehicle. Never leave a cylinder in a hot closed car.

Which cylinder is best for home use? A mid-size cylinder with a trolley is usually the most practical for a bedridden patient. Call us with the patient's needs and we will suggest an option.
