Oxygen Therapy: What Are Your Options?

Oxygen Therapy

When you’re experiencing symptoms such as dizziness, fogginess when you wake up, chest pain, constant confusion, and high blood pressure, chances are that you are suffering from low blood oxygen levels. Diseases such as chronic obstructive pulmonary disease (COPD) and certain lung cancers could be the culprit and cause of these symptoms. 

Often, when your physician diagnoses such diseases, they will prescribe oxygen therapy, which is a method of administering medical grade oxygen to individuals with breathing disorders. 

If you need oxygen for your lung condition or breathing disorder, you may have to use a portable breathing machine to enable you to continue enjoying life. 

WebMD recommends that you choose a device based on:

  • Your frequency of travel 
  • Engagement in physical activity such as going up or down the stairs
  • Your weight, physical endurance, and strength
  • Your tendency to breathe either through your nose or mouth
  • The amount of oxygen your physician prescribes

There are different types of tanks available: 

  • Home oxygen concentrator

These are also known as standard oxygen concentrators. They are devices that have to sit in your home, and are plugged into electrical outlets. This system works by pulling in air from its surrounding and filtering it, thereby removing impurities and nitrogen. As a result, you are left with medical-grade oxygen.

  • Portable Oxygen Concentrator (POC)

POC devises rate high for oxygen therapy as they are small, portable, and battery or electric powered. Because of their mobility function, you can travel anywhere with them, be it on picnics, on an airplane, and even while driving.

We reviewed 4 of the best portable Oxygen Concentrators for 2020.

  1.     Inogen one G4

This device is the best choice for users with busy lifestyles who require continuous flow oxygen.


The internal battery of this device is quite hardy, and will work for 6-8 hours but is dependent on the settings. The pulse setting is extremely quiet, and gently pulses when you take a breath. It beats bigger POCs because of its oxygen delivery, which is the same as four liters per minute.
