As a leader in the treatment and management of COPD and other breathing disorders, we’ve been asked many questions regarding oxygen therapy.
Apria’s Market Clinical Trainer and a registered respiratory therapist, Lesley Williams says, “We are always happy to answer questions about oxygen therapy: how it works, who needs it, its benefits, the types of therapy, and much more.”
Following are answers to the top 10 oxygen therapy questions.
A. People with lung diseases or breathing problems often struggle to get enough oxygen on their own. Oxygen therapy is prescribed to help supplement the oxygen their bodies need so they can perform everyday activities.
A. Oxygen therapy is often prescribed for people with the following conditions:
A. A healthy oxygen level (doctors call it “oxygen saturation”) circulating in blood is 95% or higher. If your oxygen blood level drops below 88%, your doctor will prescribe oxygen therapy.
A. When you have low blood oxygen levels (also called hypoxia), you may experience the following:
A. Healthcare providers use three methods to measure oxygen levels:
1. Pulse oximeter: A special device that painlessly clips onto your finger, toe, or ear. It sends light beams through your skin to measure the oxygen level in your blood vessels.
2. Arterial blood gas test: Similar to a standard blood test. Your doctor takes a blood sample from your arm, and a lab checks the sample’s oxygen and carbon dioxide levels.
3. Lung function tests: The most common test is spirometry, which gauges how much and how quickly you can inhale and exhale air.
A. The three most popular oxygen therapies include:
1. Compressed oxygen: Oxygen in a gas form is stored under pressure in a metal tank. The regulator on the tank controls the oxygen flow rate. It also shows how much oxygen is left in the tank; some tanks are refillable by the user while others need to be refilled or replaced by your oxygen supplier. Tanks are available in various sizes. Your doctor will recommend the most appropriate size for you. You should also have extra oxygen tanks available.
2. Liquid oxygen: Oxygen is usually a gas. But it turns to liquid when frozen. Liquid oxygen is often prescribed for people who need high levels of oxygen. When the liquid oxygen is released, it turns into gas that you breathe in. You can store and transport liquid oxygen more easily than compressed oxygen tanks. But because liquid oxygen is very cold, -2970 F, it can cause frostbite if not handled carefully.
3. Oxygen concentrators: These electric or battery-powered devices pull air from your surroundings. They then separate and remove nitrogen and other gasses and deliver purified oxygen for you to breathe, so you never run out of oxygen. Concentrators for home as well as lightweight portable oxygen concentrators are available.
A. The flow rate is the amount of oxygen that is delivered each minute by the device you are using. Your doctor will give you a prescription that specifies your appropriate flow rate.
It’s important to follow doctor’s orders: too much oxygen can cause oxygen toxicity (also called oxygen poisoning), which can slow your breathing and heart rate to dangerous levels.
A. Oxygen is generally delivered by one of these methods:
Other accessories are available to help make your therapy more comfortable and convenient:
A. Your doctor and oxygen supply company will provide instructions, including:
A. Following are simple tips to help you use oxygen safely:
