Olive Medical Oxygen Concentrator 5 Litre (OLV-5) – Reliable Home Oxygen Therapy in Bangladesh

When a doctor recommends supplemental oxygen, families in Bangladesh need a solution that is dependable, affordable and available at home. The Olive oxygen concentrator is a stationary electric oxygen machine that takes ordinary room air, removes most of the nitrogen and delivers a stream of oxygen-enriched air through a nasal cannula or mask. Unlike a cylinder, it does not need to be refilled, transported or exchanged – you plug it in, set the flow and it works for as long as there is power.

Advanced Medical Equipment supplies the Olive 5 litre oxygen concentrator to patients, caregivers, clinics and nursing-care providers across Dhaka, Chattogram, Sylhet, Rajshahi, Khulna and beyond. This page explains how the machine works, what its main features are, who it suits, how to use it safely and what to ask before you buy.

How an Oxygen Concentrator Works

Room air is roughly 21% oxygen and 78% nitrogen. An oxygen concentrator uses a process called Pressure Swing Adsorption (PSA). An internal compressor draws air through filters and pushes it into sieve beds filled with a molecular sieve material. The sieve holds back nitrogen, allowing oxygen to pass through to a small storage chamber. The beds alternate in cycles, so one is producing oxygen while the other is being cleaned. The result is a continuous supply of concentrated oxygen at the outlet, set by the flow knob and shown on the flow meter. The Olive OLV-5 specification lists an oxygen purity of 90% ± 3% across its 1–5 litres per minute flow range.

Key Features of the Olive OLV-5 Oxygen Concentrator

• 1–5 L/min adjustable flow: a flow-tube meter and knob let the caregiver set the flow prescribed by the doctor.
• 90% ± 3% oxygen concentration: a purity level in the range commonly specified for 5-litre home concentrators.
• PSA technology with molecular sieve: a maintenance-friendly design with no consumable gas to buy.
• Large LCD display and button panel: the front panel, visible in the product photo, makes the settings and running status easy to read.
• Designed for continuous operation: the distributor describes this model as suitable for round-the-clock use, which matters for patients who need oxygen overnight.
• Wheels and top handle: four castors and a carry handle make it easy to move between a bedroom and living room.
• Dual-voltage AC input: listed for 220 V / 110 V AC supply; Bangladesh households use 220 V.
• Filter system: includes a first-stage filter and HEPA filter in the supplied accessory set to protect the sieve and the patient's airway from dust.
• Humidifier connection: a humidifier bottle moistens the oxygen, which many patients find more comfortable on dry nasal passages.

Who Can Benefit from a Home Oxygen Concentrator?

Oxygen therapy is a medical treatment and must be prescribed and monitored by a doctor. Patients who are commonly advised home oxygen include:

• People with chronic obstructive pulmonary disease (COPD) or chronic bronchitis
• Patients recovering from pneumonia, severe respiratory infection or COVID-19 whose oxygen saturation remains low
• Patients with interstitial lung disease, pulmonary fibrosis or heart failure who have been assessed as needing oxygen
• Elderly patients receiving palliative or long-term care at home
• Clinics, small hospitals and nursing homes that need a back-up oxygen source in addition to cylinders

An oxygen concentrator is not a substitute for emergency hospital care. If a patient is breathless, confused, blue around the lips or unwell, contact a doctor or go to the nearest hospital immediately.

Oxygen Concentrator vs Oxygen Cylinder

Running cost: a cylinder must be refilled again and again, while a concentrator only uses electricity. Over weeks or months of treatment, a concentrator is usually the more economical option.

Convenience: there is no waiting for a delivery and no risk of running out at night, as long as the power is on.

Safety: a concentrator holds no large store of high-pressure gas, so there is no heavy cylinder that can topple.

Limitations: a concentrator needs electricity, so families in areas with frequent outages should keep a charged back-up cylinder or a power back-up available. Concentrators also produce about 90–95% oxygen rather than 99%+, which is adequate for most home therapy but may not meet the needs of every critical patient.

Setting Up and Using the Machine

1. Place the concentrator on a hard, level floor in a well-ventilated room, with at least 30 cm of free space around the air intake and sides. Keep it away from curtains, walls and heaters.
2. Fill the humidifier bottle with distilled or clean boiled-and-cooled water to the marked level, then connect it to the oxygen outlet.
3. Attach the nasal cannula or mask tube to the humidifier outlet.
4. Plug the machine into a stable power supply. A voltage stabiliser is recommended in areas with fluctuating voltage.
5. Switch on, allow the machine to warm up for the period stated in the manual, and set the flow rate prescribed by your doctor using the flow knob.
6. Check the flow meter reading at eye level and confirm that oxygen is flowing from the cannula before it is placed on the patient.

Safety Guidelines You Should Follow

• Never smoke, light candles, use gas stoves or allow open flames in the room where oxygen is in use; oxygen makes fires burn faster.
• Do not apply oil, petroleum jelly or alcohol-based creams near the connectors or the patient's nose. Use a water-based lubricant if recommended by the doctor.
• Never change the flow rate on your own. Follow the medical advice given for that patient.
• Do not cover or block the air intake and do not run the machine in a very hot, dusty or humid space.
• Use a pulse oximeter if your doctor has advised monitoring of oxygen saturation, and contact the doctor if readings do not improve.

Cleaning and Maintenance

Routine care keeps the machine efficient and extends its life. Wash or replace the intake filter at the interval given in the user manual – in dusty Dhaka conditions this is often more frequent than in cleaner environments. Wash the humidifier bottle regularly and change the water daily. Replace the cannula and tubing as advised. Wipe the exterior with a soft, slightly damp cloth while the unit is unplugged. Have the machine inspected by a qualified technician if the flow drops, the alarm sounds or the machine becomes unusually loud.

What Is Typically Supplied

The distributor specification for the Olive OLV-5 lists a spare first-stage filter, a HEPA filter, two nasal cannulas, a user manual and a warranty card. Please confirm the exact contents, including the humidifier bottle, when you place your order. Warranty length and service terms are confirmed at the time of purchase.

Frequently Asked Questions

What does 5 litre mean?

It refers to the maximum flow the machine can deliver – up to 5 litres of oxygen-enriched air per minute. This is the size most commonly prescribed for home therapy.

Can it run all day?

The model is described by its distributor as suitable for continuous operation. Always follow the user manual and keep the room ventilated.

Does it need a prescription?

Oxygen is a medical therapy. Please consult a doctor to decide whether you need it and at what flow rate.

Is it noisy?

All concentrators produce some compressor sound. Place the unit a little away from the bed and keep the filters clean to keep noise low.

Will it work during load-shedding?

No. Any electric concentrator stops without power, so keep a back-up oxygen cylinder or UPS plan for patients who cannot go without oxygen.

Do you offer installation or service?

Yes, please call our team to arrange set-up guidance, servicing and spare filters.
