Obstructive lung disease

intrapulmonary pressure, atmospheric pressure and airflow within the lungs. “Intrapulmonary pressure is the pressure within the lungs, atmospheric pressure is the pressure used in all directions at any given point by the weight of the atmosphere and air flow is simply the motion of air. Intrapulmonary pressure and atmospheric pressure are usually measured in units of millimeters of mercury. “Inspiration is the act of drawing air into the lungs and expiration is the exhalation of breath…

The second criterion that defines a disease is that a disease usually worsens if left untreated. Although not all diseases can be cured, most of symptoms and effects caused by a disease can be lessened with medications, therapy, surgery, and other treatments. For instance, a person born with asthma, a condition where the airway is being infected and swollen by certain factors such as dust or pollen, can live a healthy and productive life if he or she receives suitable treatments. Although it…

What is asthma? Asthma is a day-and-night lung weakness that lights and limits the air travel routes. Asthma reasons repeating times of wheezing (a shrieking sound when you inhale), mid-section snugness, shortness of breath, and hacking. The hacking regularly happens during the evening or at a young hour in the morning. To comprehend asthma, it knows how the flying routes work. The navigation routes are tubes that do air into and of your lungs. Individuals who have asthma have excited aviation…

Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…

and that these continuous requirements are met. Exploring the main role of the respiratory system in this process and its relationship with the cardiovascular system is best explained in 4 main steps. 1. “Uptake in the lungs 2. Carrying capacity of blood 3. Global delivery from lungs to tissue 4. Cellular use of oxygen” (Treacher &…

part of the upper respiratory system, and release toxins that damage the cilia and cause the airways to swell. Whooping cough is very contagious and usually spreads by spending a lot of time near someone who coughs or sneezes; babies tend to get the disease from caretakers or parents. People stay contagious up to about 2 weeks, but vaccines are the most effective tool and are 100% effective. Diagnosis and…

Respiratory distress syndrome (RDS) commonly known as hyaline membrane syndrome occurs in many premature births. As the gestational age for a baby decreases subsequently the likelihood of them having this condition will increase because their lungs are severely underdeveloped. The problems that stem from RDS include lack of surfactant, smaller alveolar surface span, elevated compliance of the small airways, and occasionally the ductus arteriosis might be a factor if it doesn’t close shortly…

Acute Respiratory Distress Syndrome (ARDS) occur when alveoli of the lungs are filled with fluids due to severe injury or illness. This fluid buildup instead of air in the alveolar air sacs causes decreased level of oxygen transfer from the lungs to the blood stream. A chest x-ray will show clinical appearance of acute pulmonary edema without elevated left atrial pressure or cardiogenic causes (Brochard, 2011). This will cause a severe deprivation of oxygen to vital organs and leads to…
