Physiological Processes
Gas exchange occurs because of the body’s involuntary response to breathe in response to: exchange carbon dioxide and oxygen, deliver oxygen to tissues and to regulate acid-base concentrations in the bloodstream. The air travels into the nose, down the trachea, bronchi, bronchioles, alveolar sacs then to the pulmonary capillaries. Froom the pulmonary capillaries hemoglobin picks up the oxygen molecules and travels through the arteries in the body to deliver the oxygen while picking up carbon dioxide and delivering it to the lungs through the veins and the process repeats. Since my patient has asthma along with a smaller diameter for air to pass through it causes severe inability to oxygenate the body during an asthma …show more content…

The concepts that are directly related to impaired gas exchange are: acid- base balance, perfusion, mobility, growth/development and anxiety. All these concepts were an issue when the patient first presented into the hospital; once the asthma attack was resolved and respiratory status because within normal limits these concepts resolved themselves as well. Acid-base balance is effected because the patient is breathing so fast and the body is not being able to exchange gasses affectively so there is a higher concentration of carbon dioxide in the blood than oxygen which illustrates as respiratory acidosis. Since there is decrease of oxygen in the blood the cells are not being perfused with adequate oxygen and then signs and symptoms of poor perfusion starts to be expressed. Then since the body is not being perfused well the cells and tissues do not have enough ATP to energize the cells which results in mobility issues. The mobility issues demonstrate in the patient since she got tired very easily and did not have energy to play. Also, another interrelated concept is growth and development because the patient is four years old and is still growing it is important that the body receives enough oxygen to supply the high demand for the body’s maturing features. Anxiety is also very inevitable for anyone going through an asthma attack, the body feels like it is being suffocated form lack of oxygen and the brain starts to go into fight or flight. With the patient being only four years old it is a very scary situation since she does not fully understand what’s going on and has a first reaction to want to scream and

Al 's AP chest diameter is increased ("barrel chest") from the chronic air trapping. Excess air is trapped in the lungs, which is shown in his PFTs results (NIH, 2016). The lungs are hyperinflated, which is why the RV and FRC are increased. COPD pathophysiologically prevents the trapped air from being breathed out, which is indicated by the decreased VC. 5.

Acute is a condition in which carbon dioxide builds up very fast, before the kidneys can return the body to homeostasis. Symptoms of respiratory acidosis may include: Sleepiness, easy fatigue, confusion, and shortness of breath and lethargy. Treatment is aimed to the underlying disease, oxygen if the blood level is low, treatment to stop smoking, Noninvasive positive-pressure ventilation (called CPAP) or a breathing machine and some Bronchodilator drugs to reserve airway obstruction. Compensation refers to the body 's natural mechanisms of counteracting a primary acid-base disorder in an attempt to maintain homeostasis. In Respiratory Acidosis, the elevation in PCO2 result from a reduction in alveolar ventilation.

The trading of gasses in the middle of air and blood happens cross the dividers of respiratory alveoli. Alveoli are microscopic flimsy walled air sacs that give a colossal surface zone to gas dispersion. The locale of the lungs where gas trade with the blood happens is known as the respiratory zone. The trachea, bronchi, and bronchioles that convey air to the respiratory zone include the leading zone. The thoracic cavity is constrained by the mid-section divider and diaphragm.

Hyaline membranes help to the development of fibrosis and atelectasis (collapse) essential to decrease in gas exchange capability and lung dysfunction. These changes cause the lungs to become stiff, patient work hard to inspire. Hypoxemia and the stimulation of juxtacapillary receptors in the stiff lung parenchyma leading to increase respiratory rate and decrease in tidal volume. Breathing irregular increase carbon dioxide removal,

While Jose and Jorge are identical twins, their lives could not have been any more different. They have different health determinants to their unfortunate diseases that differ from each other. The case study of Jorge and Jose emphasizes the idea that your zip code determines your health more than your genetic code. Just a quick reminder, Jose is the twin who grew up in a largely improvised family, while Jorge is the twin who grew up in an upper-middle-class family. Since both brothers have asthma it can be assumed that the brothers have asthma in their genetics, however, needed to be triggered.

From these questions that were given out by Dr. Frander, many students should have a great understanding what to expect to the mid-term exam. Dr. Frander really encouraged us to study because most of these questions are difficult. For instance, she gave us an example in a patient who has COPD/ emphysema. What we have concluded from this question what they are looking for the emphysema patients don’t have a problem of taking air in rather they have a problem of taking the air out. The main problem of the emphysema, they have a lot of mucus, and the alveoli which where the gas exchange takes is impaired.

Annette’s reason for admittance at the hospital is an overall weakness, flu-like symptoms, and difficulty with breathing (Prizio, n.d.). She is diagnosed with diabetic acidosis, left upper lobe pneumonia, and a bacterial infection (Prizio, n.d.). Unfortunately, her condition becomes worse. Annette’s right lung collapses, her heart rate is irregular, and she has an episode of unresponsiveness that leads to mechanical ventilation (Prizio, n.d.). Annette has challenges weaning off the mechanical ventilation, which resulted in the placement of a tracheostomy and percutaneous endoscopic gastrostomy tube (Prizio, n.d.).

The alveoli is filled with fluid. The lungs are not able to expand fully to get enough air in due to the inflammation and exudate. Therefore, when the carbon rich blood comes to the lungs to be oxygenated, there isn’t enough oxygen to fully oxygenate the blood. If this continues overtime, the rest of the body will become hypoxic because of the low oxygen levels.

The diaphragm and accessory breathing muscles are challenged with increased demands on inspiration, and elevated lung resistance and compliance. Concurrently, the efforts of the muscles of inspiration to produce pressure is decreased due to disadvantageous mechanical nature inflicted by hyperinflation.4 Abnormal gas exchange will also occur and oxygen levels will decrease progressively throughout the disease, which can be identified when examining arterial blood gas (ABG) values. COPD is divided into two types which includes emphysema and chronic bronchitis. The two conditions can be differentiated by assessing ABG values. ABG values indicating emphysema demonstrate a decrease in PaO2 and CO2, whereas chronic bronchitis is noted to have an increase PaO2 and

The doctors had constantly told me that I would never be able to do things that would require me to do physically taxing activities. I was told that I would never be able to sing, dance, or play any kind of sport ever. I was distraught at this fact because at that time I was very passionate about playing soccer and participating in my elementary school’s choir. My asthma prevented me from living my life to the fullest. I had to take what felt like thousands of

To start, the bronchial airways are much more stressed even when relaxed. At the same time, the mucus layer on the side of the muscles is increased to a thick level. When an asthma attack happens, the muscles tighten up and trap air in the alveoli, making it very hard- if even possible- to breathe. Asthma attacks the integral function of our body, but this is because of a malfunction- not a virus. Researchers say there may be a gene for asthma that may open new doors for asthma research.
