why do some people need oxygen tanks

There are a number of different types of oxygen therapies that can be used. These include:
Oxygen gas can be stored in a portable tank. These are called compressed gas systems. A larger stationary concentrator is used within the home, and a smaller oxygen tank can be taken to use outside the home. The smaller tanks might be used along with oxygen-conserving devices so that the oxygen supply lasts longer. The oxygen is delivered in pulses, not continuously. Liquid oxygen also can be stored in a portable tank. Liquid oxygen is more highly concentrated, so more oxygen can fit in a smaller tank. This is helpful for people who are very active, but it will evaporate if it isnвt used in a timely manner. These tanks are refillable. Both liquid oxygen and oxygen gas are available for home delivery in many locations. Oxygen concentrators are less portable than the other options. An oxygen concentrator is a device that takes oxygen from the room, concentrates it for therapeutic use, and removes other naturally occurring gases. The benefits of concentrators are that they are less expensive and donвt require filling like tanks. Portable versions are available. However, most models are too large to be truly portable. Oxygen is distributed from the tank through a tube. It enters the lungs through nasal tubes, a face mask, or a tube inserted directly into the personвs windpipe. Hyperbaric oxygen therapy is unlike the other methods of oxygen therapy.

People will breathe in pure oxygen in a pressurized room or chamber. In the hyperbaric chambers, the air pressure is increased to three or four times the normal air pressure levels. This increases the amount of oxygen delivered to the bodyвs tissue. This type of oxygen delivery is often used to treat wounds, serious infections, or bubbles of air in your blood vessels. Hyperbaric therapy should be carried out carefully so that blood oxygen levels donвt become too high. The most common delivery method is the, which consists of a tube that runs through both nostrils. Other delivery methods include: Sometimes people with COPD need to inhale more oxygen than what is provided in the air. PThe way this is accomplished is by using oxygen therapy. PSo what is oxygen therapy, and do you need it? Oxygen in room air contains 21 percent oxygen. PUsually this is plenty of oxygen. PHowever, certain disease conditions, such as what may occur as, or during COPD flare-ups, may create areas inside your lungs where oxygen is inhaled, but cannot get to your bloodstream. PWhen enough of these areas exist, your blood oxygen levels may decline. To learn more about oxygen and oxygen levels, please read my post. M What is oxygen therapy **? ** It involves inhaling supplemental oxygen, or oxygen percentages that are greater than 21 percent. PIt allows you to inhale 22-100 percent oxygen, depending on the device used.

Nasal Cannula. P This involves inserting prongs into your nose. PA low flow allows you to inhale anywhere from 22-44 percent oxygen. PThis is all that is needed for most people with COPD. PIt is very comfortable and tolerable. Masks. PA variety of masks can used to provide up to 100 percent oxygen. PThese are not used very often, but are available if needed. To learn more about oxygen devices read my post. M There are three ways of getting oxygen therapy into your home. Compressed Oxygen Gas Cylinders. These are tanks with regulators and flowmeters. PSome are larger and stay at your home, and some are smaller for travel. Liquid Oxygen. They hold more oxygen and are smaller and more lightweight, making them ideal for people who are constantly on the move. Oxygen Concentrators. PThey are electronic devices about the size of end tables that make oxygen by concentrating oxygen from room air. PThese are nice because, so long as you have electricity, you always have a source of supplemental oxygen. These are described in more detail in the post. M Most people who require oxygen therapy will use oxygen concentrators at home, and have a variety of tanks as a backup in case of a power outage, and also for travel. Do you need oxygen therapy **? ** PIf your oxygen levels are chronically low, this puts strain on your body that can shorten your lifespan.

PThat said, supplemental oxygen is the only drug proven to prolong life. Common signs and symptoms of low blood oxygen levels (hypoxemia) are. Bluish tinge to your fingertips, toes and lips Feeling winded, especially with exertion If you, or a loved one, observes these signs, you should seek medical attention immediately. PYour doctor may at first treat your COPD flare-up. POnce you are deemed to be in a chronic stable state, M your doctor may qualify you for oxygen therapy. **Do you qualify for home oxygen therapy? P**The are set by the Centers for Medicare and Medicaid Services (CMS), and they prefer numbers over subjective signs and symptoms. PSo qualifying is determined by the following test results: PO2 is 55 or less or your SpO2 is 88 percent or less at rest while breathing room air. PO2 is 55 or less or your SpO2 is 88 percent or less while you are sleeping; or, if your PO2 drops 10 percent or more, or your SpO2 drops 5 percent or more, while you are sleeping, and you are also displaying symptoms of hypoxemia. PO2 is 55 or less or your SpO2 is 88 percent or less while you are exercising. How much oxygen do you need? PThe goal of oxygen therhapy is to provide you with the least amount of supplemental oxygen to maintain an SpO2 at 90 percent or greater. PUsually, a low flow of 2-3 LPM using a nasal cannula works great. PAnd, considering the benefits, most people tolerate it very well.
