On the periodic table‚ oxygen is the 8th element. It is located in period 2 and group 16. Oxygen is classified into many things. For example‚ on the periodic table‚ oxygen is classified as a nonmetal gas with an atomic number of 8 and atomic weight of 15.9994. In addition‚ it has 6 valence electrons. The symbol of oxygen is O and oxygen has 8 protons‚ 8 neutrons‚ and 8 electrons. The electron configuration of oxygen is 1s2‚ 2s2‚ 2p4. Oxygen had been produced by several chemists prior to its discovery

the lungs. The trachea pulls air into the lungs via the bronchi. The bronchioles then are a functional branch of the bronchi. The tiny pockets of alveoli store air briefly in order for oxygen to be absorbed in the bloodstream. Through the alveoli the gas exchange into the lungs occurs. Pathophysiology of COPD COPD stands for Chronic Obstructive Pulmonary Disease. It is typically caused by inhaled irritants such as tobacco smoke. It is a chronic inflammation of the airways‚ lung tissue‚ and pulmonary

Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism‚ the means by which animals derive the energy needed to sustain life. Furthermore‚ oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores‚ earths‚ rocks‚ and gemstones‚ as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic

After consultation the surgeon informs Paul that he will require a shoulder arthroscopy with rotator cuff repair followed by rehabilitation. The rotator cuff is a group of muscles and tendons (supraspinatus‚ infraspinatus‚ teres minor and subscapularis) attached to the bones of the shoulder joint. The rotator cuff connects the humerus (upper arm) to the scapula

disease Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease that results in obstructed airflow from the lungs. When a person takes a breath‚ air travels down the windpipe into airways. These airways scatter into smaller‚ much thinner tubes that end in a bunch of tiny air sacs. These air sacs stretch and inflates when a person breathes in and then deflates when the person breathes out. When a patient is diagnosed with COPD‚ their lung function is greatly lessened with air

Treatment for COPD Inhaled Therapies NICE COPD guidelines have made specific recommendations regarding the use of inhaled long-acting bronchodilators and inhaled steroids separately and in combination‚ but newer studies have assessed these drugs singly and in combination over longer periods of time. Bronchodilators (relievers) Short-acting beta2 agonists (SABA) Beta2 agonists act directly on bronchial smooth muscle to cause bronchodilation. They are the most widely used bronchodilators for COPD.

What is COPD? Chronic Obstructive Pulmonary Disease is a progressive disease that constricts airways and dramatically hinders a person’s ability to breathe. It affects around 13% of Australians aged 40 or over. It causes mucus or blood-filled coughing‚ chest tightness and severe shortness of breath. The disease is comprised of Chronic Bronchitis‚ Asthma and Emphysema‚ with the seriousness of it being judged by four levels‚ each level increasing in severity. To this day‚ there is no known cure
