How is COPD diagnosed?

Oxygen Therapy COPD

The most common test ordered by the doctor to detect COPD is the Spirometry test. This test is painless and essentially measures how well your lungs work. The patient simply blows air into a mouthpiece with tubing attached and the machine measures the amount of air that the patient can blow out and how fast they can blow it.

This test can detect COPD even before symptoms develop!

Other tests can include a chest x-ray or an arterial blood gas test, which can establish the oxygen level in the patient’s blood.

COPD is most commonly diagnosed in middle-aged and older adults. Remember, COPD is not contagious.

How is COPD treated?

Oxygen Therapy COPD

The prescribed treatment for COPD is dependent on the patient and their stage of the disease. For some, treatment will include a prescribed inhaler, while others will need to get the assistance of supplemental oxygen delivered via a portable oxygen concentrator, stationary oxygen concentrator or liquid oxygen system.

It is important to follow the treatment plan that you and your doctor decide upon. Explore all of CAIRE’s oxygen therapy products and talk to one our oxygen experts.

FAQs of Oxygen Therapy How do I select which oxygen therapy device is best for me?

How do I select which oxygen therapy device is best for me?

Selecting an oxygen therapy device is based on your prescription from the doctor. Devices range in size and weight based on the amount of oxygen they deliver to the patient. CAIRE’s smallest portable oxygen concentrators deliver pulse flow only. If continuous flow or higher pulse flow settings are required larger units must be employed to deliver oxygen to the patient. Regardless of your prescription, CAIRE offers the full continuum of care for your oxygen therapy.

What is the difference between continuous flow and pulse flow?

Continuous flow delivers oxygen continuously to the patient dosed and prescribed in liters per minute (LPM) by your doctor. It is typically used for at home and during sleep at a minimum. It is also used for portability for patients in disease states that will not allow them to tolerate pulse flow. CAIRE’s stationary oxygen concentrators all provide continuous flow settings for at home use. And our transportable concentrators provide continuous flow options for portability.

Pulse flow delivers oxygen intermittently when the user inhales through their nose. The oxygen device senses inhalation and delivers a bolus (a puff of oxygen) with each breath. Pulse flow is general used for portability exclusively because it conserves oxygen to extend battery life and/or activity time. All CAIRE portable and transportable provide pulse flow settings.

How do I know that I can use pulse flow for portable oxygen therapy?

Pulse flow must be prescribed by your doctor. Your doctor can perform tests to establish if your breathing patterns or disease state will allow your oxygen levels to stay up during pulse flow.

Do I need a prescription for an oxygen therapy device?

Yes. Oxygen is considered a prescription drug and a prescription from your doctor must be presented to receive an oxygen therapy device. Your prescription generally will specify your flow rates for continuous or pulse flow use.

Can I travel with my oxygen concentrator on an airplane?

Yes. All CAIRE portable and transportable concentrators are FAA Approved. Our products also are functional in your car and can be charged or operated on DC vehicle power. Visit our Travel Page.

Why is a portable oxygen concentrator better than a traditional oxygen cylinder?

A portable oxygen concentrator offers patients more freedom and time away from home. Oxygen cylinders have a limited supply of oxygen and require the patient to carry multiple tanks or limit their time away from home based on their supply of oxygen. With a portable oxygen concentrator you never have to worry about running out of oxygen because they run and recharge on both AC and DC power. Oxygen concentrators also allow you to maximize travel because they are FAA approved and can be used in the car during road trips. There are no limits on your lifestyle with a portable oxygen concentrator.

What is the difference between stationary, portable and transportable oxygen concentrators?

A stationary oxygen concentrator is designed to be your at home oxygen therapy device. Using tubing extensions attached to their nose cannula, you are able to move about doing regular activities. Stationary oxygen concentrators are also used at night for sleep. CAIRE’s stationary oxygen concentrators include the AirSep VisionAire 5, CAIRE Companion 5, AirSep NewLife Elite and Intensity, and AirSep SureFlow. Stationary oxygen concentrators are larger in size (typically 30 pounds or more) and provide only continuous flow.

A portable oxygen concentrator is designed to help the patient take their oxygen anywhere. This device is wearable – on a belt or from a shoulder strap. CAIRE’s portable oxygen concentrators are the AirSep Focus, the AirSep FreeStyle and the AirSep FreeStyle 5. Portable oxygen concentrators typically provide pulse dose only.

A transportable oxygen concentrator is a device that is typically attached to wheels or cart mechanism because it weighs too much to be wearable. It is easy to use and navigate. CAIRE’s transportable oxygen concentrators are the SeQual Eclipse 5 and the SeQual eQuinox. Transportable oxygen concentrators typically provide both continuous and pulse flow options. They can be used at all times during the day, for both stationary and portable use.
