Slate is a metamorphic rock. Metamorphic rocks are formed when sedimentary or igneous rocks are exposed to conditions of very high pressure or temperature, or are exposed to large amounts of very hot water.Slate is formed when fine-grained sedimentary rock (shale) is buried and exposed to high pressure deep beneath the Earth's surface.gneous rocks are formed from melted rock that has cooled and solidified. When rocks are buried deep within the Earth, they melt because of the high pressure and temperature; the molten rock (called magma) can then flow upward or even be erupted from a volcano onto the Earth's surface.
As a patient with COPD, your health care provider may determine your oxygen levels at rest, while sleeping, or during exercise to see if oxygen may help you. If your oxygen levels are low, oxygen therapy will help reduce the strain on your heart, brain, and muscles, and using oxygen as directed may help you feel better.
If you have COPD, you may have trouble eating enough because of your symptoms, such as shortness of breath and fatigue. (This issue is more common with severe disease.). As a result, you may not get all of the calories and nutrients you need, which can worsen your symptoms and raise your risk for infections.f you have severe COPD and low levels of oxygen in your blood, oxygen therapy can help you breathe better. For this treatment, you're given oxygen through nasal prongs or a mask. You may need extra oxygen all the time or only at certain times.
