Oxygen Therapy FAQs

Home Oxygen Concentrator


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.

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.

It can be used 24X 7 with 5 to 10 minutes gaps after 3 to 4 hours so that heating problem does not arise.

Filter can be changed any time after usage of 4000 hrs but before 5000 hrs for better purity and prolong life.

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

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.

This mode enables the Oxygen Concentrator to produce Oxygen only when the patient is inhaling and not otherwise; hence, reducing the load on the machine. When a patient inhales, it causes negative air pressure which activates the Oxygen Concentrator to provide Oxygen at that very moment as and when required.

Continuous flow means the Oxygen produced by the machine is being delivered continuously to the patient, whether the patient is inhaling or exhaling.
