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.
Exercises. Different types of exercise can help COPD patients in different ways, for example: 1  Cardiovascular exercise involves steady aerobic activity that uses large muscle groups and strengthens your heart and lungs. 2  This type of exercise improves your bodyâs ability to use oxygen.
