Anatomy and Physiology of the Upper Airway Brining oxygen into the body There are two ways in which a person brings oxygen into the body: …show more content…
As oxygen passes through the trachea it makes way down to the main bronchi. As air enters the bronchi it will either go to the left or right bronchus into the lungs. "The right main bronchus has a larger diameter, is oriented more vertically and is shorter than the left main bronchus. The practical consequence of this arrangement is that foreign bodies passing beyond the larynx will usually slip into the right lung" (Britannica). After the oxygen molecules enter either the right or left lung through the bronchi it then enters the smaller divided region called the bronchioles. The bronchioles are lined with smooth muscle tissue making the bronchioles able to constrict or dilate allowing the amount of air able to move in and pit at the end of the bronchioles the there are air sacs called alveoli where the capillaries meet and gas exchange occurs. At capillaries you have capillary beds which connect the arterioles and the venules. The atrioles play a role in the respiratory system by bringing blood from the heart which has nutrients and oxygen rich blood while the venules are responsible carry deoxygenated blood back from the …show more content…
A person in respiratory arrest is experiencing shortness of breath because they are continuing to lose oxygen and their blood oxygen level will decrease below 94%. Respiratory distress begins when the capillaries are not getting enough oxygen which will cause a decrease in perfusion making your blood oxygen levels drop and cell death will begin to occur as your body becomes hypoxic. There are many signs and symptoms that go along with respiratory distress that include: a chief complaint of shortness of breath, restlessness, an increased pulse rate in early distress, skin color changes, abnormal breathing, difficulty speaking from shortness of breath, altered mental status, excessive coughing, tripod positioning and a decrease in their pulse ox level (Mistovich, 449). Patients who are in respiratory distress will always need oxygen but those who are in early distress are possibly able to use a nasal cannula to slightly increase or maintain an adequate blood oxygen level of 94%. But, for those patients who are in the later stages of respiratory distress or severe hypoxia are going to need to be administered oxygen through a CPAP in order to bring the levels up and get enough oxygen into the capillary beds. Lastly, a patient who may present with severe hypoxia and severe levels of
