Using Oxygen at Home:What You Need to Know

Oxygen is what your body needs to work properly. Your cells need oxygen for energy. Your lungs absorb oxygen from the air you breathe. Oxygen travels through your blood from your lungs and to your organs and tissues.

Some medical conditions can cause low levels of oxygen in your blood. Low blood oxygen may make you feel shortness of breath, tired, or confused. It can also damage your body. While oxygen therapy can help you get more oxygen.

Oxygen therapy is a therapy that gives you extra oxygen. It's also known as supplemental oxygen. It can increase the arterial oxygen partial pressure, improve the tissue hypoxia caused by the decrease of blood oxygen, and maintain the functions of the brain, heart, kidney, and other important organs; It can also reduce the workload of the heart and lung caused by increased heart rate and respiration during hypoxia. It has a good effect on respiratory diseases caused by decreased arterial oxygen partial pressure. It can only partially improve the hypoxic condition in patients with circulatory dysfunction or anemia. It is worth noting that oxygen therapy can only be obtained through the prescription of your health care provider. You can get it in hospitals, other medical institutions, or at home. According to the individual situation, some people only need a short period, some people will need long-term oxygen treatment.

Different types of devices can provide you oxygen.

The nasal cannula is used in nonsevere cases, or if there is only mild hypoxia. (e.g. saturation is maintained at 92% stably in patients without lung disease). It's a soft plastic tube with two small tips at one end. They go into your nose, the tube goes into your ear and holds it. The other end is connected to your oxygen supply. Nasal intubation delivers stable oxygen. It makes your nose dry.

Non-rebreather masks can deliver 85-90% oxygen for patients with acute disease. A non-breathing mask is a mask that covers the nose and mouth. It has two check valves: one is located between the mask and a plastic reservoir (usually 1 liter) connected to the oxygen supply. The valve does not allow exhaled air or outside air to enter the airbag, so only oxygen flows from the airbag to the mask. The other valve allows exhaled air to enter the atmosphere but does not allow outside air to enter. If you need high levels of oxygen, but don't need help breathing. Covering the nose and mouth, the non-rebreathing mask has two check valves. A valve allows oxygen to be drawn in from a bag attached to the oxygen source.

Venturi Mask is a kind of low-flow mask. When pure oxygen is transported through small holes, it uses Bernoulli's principle to inhale indoor air, to produce a larger total flow under predictable FiO2. Venturi mask can provide 24-60% oxygen. Different color models have different oxygen flow rates. The venturi mask is often used in COPD. Notably, it is important not to over oxygenate the patient.
