Frequently Asked Questions (FAQs)

Q1. Will my body get dependent on Oxygen if I use it continuously?

No, Oxygen is not addictive at all. A large number of patients express their concern regarding this and try to decrease the time they are on Oxygen or totally avoid it.

Supplemental Oxygen is prescribed because the lungs have become weak due to condition like COPD and the 21% Oxygen of air is now not sufficient for lungs which results in low level of O2 in blood.

In order to make lungs feel like as if they are exactly in a normal healthy environment, they need some extra Oxygen so that the Oxygen exchange with blood is exactly same as it would have been with normal healthy lungs.

Q2. Can I use more Oxygen than prescribed?

No, using more than prescribed oxygen can cause Oxygen toxicity/Oxygen poisoning in the body which has many harmful effects like damage to eyes, acute respiratory distress syndrome (ARDS), alveolar damage, destruction of neurons , etc.

Q3. Is it alright if I use less than prescribed Oxygen?

No, you should use Oxygen exactly as prescribed by the physician. Using less than prescribed Oxygen can cause low levels of Oxygen in blood which can further cause poor memory, irritable mood, poor cognition, shortness of breath, headaches and much more.

Using less than prescribed oxygen for longer periods of time also deteriorates lung’s health and causes the disease to grow.

Q4. How much Oxygen is ideal for me?

The ideal amount of Oxygen is decided by your physician; he does it by carefully analyzing your ABGs. In most cases, the goal is to keep your Oxygen levels above 88% which after prescription is monitored using Oximetry. In healthy individuals, ideal saturation of Oxygen in blood is 95-99%.

Q5. Do I also need to keep an Oxygen Cylinder at home if I am using a concentrator?

It is recommended to keep an Oxygen cylinder as a backup source. After all, concentrator is a machine and any machine can fail anytime.

Q6. What are the common sources of Oxygen for therapy?

There are mainly 3 sources of Oxygen for therapy:
Oxygen Concentrators: Machines that concentrate Oxygen from room air. Just need a power source to work. Main article: Oxygen Concentrator
Oxygen Cylinder: Compressed Oxygen in a cylinder – Conventional way of Oxygen therapy.
Liquid Oxygen: Usually used in central supplies of hospitals. Liquid oxygen is stored in freezing cold tanks and allowed to boil at 90.188K (-186.92°C) to release Oxygen gas.

Q7. What are the common Oxygen delivery systems that can be used?

Do not confuse Oxygen delivery systems with the Oxygen sources listed in the previous question. The Oxygen delivery systems are used to deliver Oxygen from sources like Oxygen concentrators or cylinders to nose or mouth.

The most commonly used delivery systems are Nasal Cannula and simple Face Mask. Some of the other Oxygen delivery systems are reservoir cannulas , trans-tracheal catheters, non-rebreathing face masks with reservoir and one way valve and venturi masks.

Q8. Which is the best Oxygen Concentrator brand for me?

All brands are good; the most important thing is that the Oxygen Concentrator you are planning to buy should carry some international approvals like FDA, CE & ISO.

The second most important thing is that the specifications should suit your requirement. The parameters you can consider to compare different models of different brands can be flow rate, battery backup, alarms (especially low purity of Oxygen), weight, power consumption and portability.

Q9. Can I use a portable Oxygen Concentrator while sleeping?

Yes, Portable Oxygen Concentrators (POC) can be used while sleeping. Note that POCs have 2 modes: Pulse mode and Continuous mode.

In Pulse mode, POCs will work as long as you breathe through nose and that too with sufficient pressure to trigger a breath in the machine. It is recommended to use POC with high sensitivity as during sleep the triggering pressure of each breath drops.

For sleep, continuous mode of Oxygen is ideal because while sleeping, there are chances that patient may not breathe through nose all the time which means if patient is breathing through open mouth then there are less chances of activating a pulse mode concentrator.

However, you must consult your physician before using a particular POC for sleep.

Q10. I feel that Oxygen coming out of the Oxygen machine is not as effective as that from a cylinder. What should I do?

You feel this because the temperature of Oxygen coming out of the machine is exactly the same as room temperature. However, this is proven that effectiveness of Oxygen from both the sources is virtually the same. What you need to see is the Oxygen saturation in your blood and you can check this using an Oximeter.

Q11. When do I need to use a humidifier bottle?

The purpose of humidification is to provide moisture which makes Oxygen therapy comfortable; if not used, can cause dryness in airways of nose and throat. Usually, use of humidifier is recommended in continuous flow of more than 3 LPM.

Q12. My Portable Oxygen Concentrator (POC) doesn't have humidifier connection. What do I do?

That may be because your POC is a pulse flow only POC. In Pulse Flow, Oxygen is delivered only when patient inhales which doesn't cause dryness unlike continuous flow of Oxygen, therefore, humidification is not required.

However, if your Portable Oxygen Concentrator has continuous flow option then you need to talk to your equipment provider.

Q13. What kind of water should I use in humidifier? How often should I clean it?

It is recommended to use clean drinking water for humidifier as after all you are going to breathe through it. There is no hard and fast rule for cleaning but there is no harm in having good daily cleaning practices just by rinsing through fresh water and replacing the water in the bottle.

Q14. Should I use a nasal cannula or a mask?

Most people prefer nasal cannula as it doesn’t look medical but most cannulas have a limitation that they are effective for flows up to 6 Litres Per Minute (LPM). There are special cannulas for higher flow (you may check with your equipment provider).

However, if you get rashes in your nostrils by use of cannula or if your flow requirement is above 6 LPM then a simple face mask is used by most people.

Q15. Can I use all Oxygen Concentrators with CPAP or bi-level devices?

All the concentrators with continuous flow can work with PAP devices. All stationary/home concentrators have continuous flow but some portable models have just pulse flow mode. Pulse flow is not suited for use with PAP devices.

My mom is 75 and suffering from ILD. She is also a diabetic patient. Currently she is using LPM at 1.5 however when she goes to washroom it drops the oxygen level to 58-60. I have recently increasing the LPM to 4 only when she goes to washroom then again reduce to 1.5 after few mins. Have few questions 1)Is it ok to Increase the oxygen level to 4? 2) can someone recommend some good pulmonologist in Gurgaon 3) Is there any reliable digital oxygen concentrator which can increase the oxygen level with up and down buttons as due to weak eye sight she is unable to increase the LPM of her own as the level ball is not visible to her.

Hi Abdullah, you will have to use oxygen cylinder for your mother as there is no portable oxygen concentrator that provides continuous flow more than 3 LPM. If you are looking for a stationary oxygen concentrator then you should go ahead and buy Airsep Intensity 10 which provides upto 10 LPM of continuous flow. We can't comment on the availability in Pakistan as we don't have the database of dealers in Pakistan.

I'm otherwise very healthy, fit and of normal weight etc. I'd like to use an oxygen concentrator at night just to blow extra oxygen at me while sleeping, frankly I don't think I'd be able to wear a mask or cannula - any suggestions? Thanks so much.

Hi Janie, you should not use oxygen concentrator without consulting your doctor because supplemental oxygen should only be taken if the oxygen saturation in your blood is low. From what you have described, it is likely that you would need a CPAP machine.

Oxygen Times
Replied on: 2017-09-05 at 23:13:47
Hi Ralph, you need to consult your doctor about how long and how frequent you need to use the concentrator in a day. To use it, you have to turn the concentrator on from the main supply, then you need to switch it on and set the LPM flow on your flowmeter. Simply attach the nasal cannula or mask to the nozzle and you are good to go.

I have COPD but when I go to the doctor my 02 levels are normal. I smother and my 02 level ranges from 90-94 most of the time according to my oximeter. My dad was like me and he died with COPD and his heart. My mom had to find a doctor who would prescribe 02 for him because his regular doctor would not. EVen when I had severe pneumonia in both lungs my 02 levels remained between 93-95 yet I was on 02 in the hospital.I have the same problem daddy had,in that the local doctor seems to think I don't need 02. Smothering is terrible. What should I do? I have my dad's 02 concentrator and I use it when I know I need it,usually around 2L-3L and it helps. Symbicort does not stop the smothering.

Replied on: 2017-07-17 at 00:24:45
Hi Anita, it is not recommended to use supplemental oxygen without the prescription of a qualified doctor as too much oxygen can cause oxygen toxicity. The normal oxygen saturation levels in human body is 95-100%. Usually the doctors prescribe oxygen therapy when the oxygen saturation in your blood goes below 92% and the patient is having respiratory illness or breathing difficulty. Since you are facing problems and at the same time you have COPD, best would be to take second opinion and go to a couple of more pulmonologists and see what they have to say. If all of them suggests that you don't need supplemental oxygen then there must be some reason for not prescribing oxygen as there are other factors like resting partial pressure of oxygen (PaO2) that weigh in when the doctor prescribes supplemental oxygen. Hope this helps!

Hi Malak, the lifespan of an oxygen concentrator largely depends on how you maintain it. If the machine is going through regular servicing, change of filters and proper cleaning then it can work for more than 15,000 hours. After that you will either have to get the sieve beds or the compressor replaced.

My mother is using Philips Evenflow concentrator for past 6-7 months. She is suffering from ILD. The doc has asked her to user this for at least 18 hrs a day. Recently I spoke with a Oxygen service provider and came to know that concentrators should be used only for 5-5.5 hrs at a time and then switched off for 1-1.5 hrs and then use again. Is this information correct?

Hi Sidhesh, Oxygen concentrators are made in such a way that they can work continuously for days. However it is recommended to give the machine a rest of 30 minutes after using it continuously for 7-8 hours. This increases the durability of an oxygen concentrator.

My sister has been recommended to have oxygen supply ready at home. 2litres a minute. At Chennai I find dealers willing to rent oxygen concentrators from Rs 4500 to Rs 10000. Why this high range?

Hi Anamika, different dealers work on different profit margins. Rent also varies based on product availability in market. Usually you can get a 5 LPM oxygen concentrator with monthly rent of Rs. 5000 - Rs. 6000.

Hi Kim, you can use his oxygen machine. Just make sure you use your own nasal cannula.

Hi Dilip, there are no home concentrators with battery backup in market at present.

Hi Dilip, We had used an inverter with a battery bank suitable for about 2 hours backup .

Hi! Would an Inogen At Home concentrator work in my car using a 400 watt inverter?
Oxygen Times
Replied on: 2016-04-29 at 21:42:13
Hi Terry, you need at least a 700W inverter for Inogen At Home to work. And it is a home concentrator not suitable for use in car.
Posted from India on: 2016-03-17 at 01:38:57
We have an oxygen concentrator at home and have been advised 24 hours use of oxygen. Wanted to check if the machine can be kept on continuously or will need to be switched off at periodic intervals - Maybe 10-12 hours or it should be stopped for 1 hour a day, etc.

Hi Linette, for long life of the machine, best practice is to give machine rest of about 20-30 minutes after every 7-8 hours of use.

Is the humidifier bottle a prescription ? or can I just buy one at a DME?
Oxygen Times

Hi Angie, humidifier bottle is not a prescription. As per AARC guidelines, you need humidifier only when your oxygen requirement is more than 4LPM.

Will my portable concentrator work state to state? Will it be ok to sleep with?
Oxygen Times
Replied on: 2016-01-20 at 01:31:22
Yes Donna, a portable concentrator can work from state to state. For use during sleep, stationary concentrator or a portable with continuous flow is better than a pulse only POC. Read Answer of Question 9 on this page for more details.

My father is 94 Yrs old, paralytic bed ridden patient. Due to his decreased lungs performance our doctor has advised to use an oxygen concentrator. Now, we are using it for 12-13 hrs continuously during night times. In the daytime we use it in breaks. His need for oxygen may increased in the future so we may have to use the machine for 24 hrs continuously. Which model do you recommend between Phillips Everflo and Airsep VisionAire 5 and NewLife Elite. This will help us to buy an appropriate concentrator for him. Thanks

Hi Raghuram, AirSep NewLife Elite is one of the oldest machine in Indian market and has been a consistent performer known for its reliability. Considering the kind of requirement your father has, this looks like a good machine for him. Hope this helps.

In your review of the AirSep models, you note that it might be too heavy for older people; yet, the Inogen model is somewhat heavier and you don't mention its weight as possibly being a negative. Why?
Oxygen Times
Replied on: 2015-11-07 at 01:50:10
Hi Gene, we understand that this is in reference to review of AirSep Freestyle 5 portable oxygen concentrator in which our exact words are: 'Not so light to carry especially for old people'.
AirSep Freestyle 5 weighs 2.8 kg (6.2 lbs) which is definitely not very light to carry on shoulders for long periods of time whereas the Inogen One G3 portable oxygen concentrator is 20% lighter weighting 2.2 kg (4.9 lbs). This may not look like a big difference but from what we have seen, this extra 600 grams (1.3 lbs) makes considerable difference in case of old patients when they are on supplemental oxygen. Hope this answers your question.

You have mentioned respironics everflo Q model in comparison with other models but i could not find the model with any Philips dealer they say that there is only the everflo model available, everflo Q is not introduced in india. Is this correct or do you know of a dealer who has it, and can you also compare the two everflo vs everflo Q and advice. Thanks.
Oxygen Times
Replied on: 2015-08-17 at 08:21:39
'Q' in Everflo Q stands for 'Quiet'. Sound level is the only difference between both models. Sound level of Everflo is 48dB as compared to 40dB of Everflo Q. Consider calling Philips Channel Partners and if you don't find it with them then clearly this model is still not available in India.

I am in normal health. I went to an "oxygen bar" over the weekend and noticed positive effects. Any reason not to buy one of these machines just for general well-being or sports performance?

Hello Gary, American Lung Association has stated that "there is no evidence that oxygen at the low flow levels used in bars can be dangerous to a normal person's health"; so if you notice the positive effects there is no reason not to buy the machine. Just remember that over intake can cause Oxygen Toxicity.
