An elderly, 70-year-old, female patient with a viral infection of the…

- - - - Low blood oxygen level
  - - - Unfortunately, the lungs respond to the lack of oxygen by tightening the blood vessels
  - - - Yes, because people older than 65 are most likely to develop pneumonia.
      - Since she had a viral infection in her lung, it could lead to contracting pneumonia, which probably means she has viral pneumonia
- - - - 2. Oxygen diffuses from the blood into the alveoli
        
        3. More water vapor is present within the alveoli because of the higher humidity there.
  - - - Trachea (windpipe)
      - Bronchi
      - Bronchioles
      - Superior Lobe
      - Middle Lobe
      - Inferior Lobe
      - Primary Bronchus
      - Lobar Bronchus
      - Segmental Bronchus
      - Cardiac Notch
    - - Epithelial cells
      - Nerve cells
      - Hormone-producing cells
      - Blood cells
      - Structural or supporting cells
  - - - States that at a constant temperature, the pressure (P) of a gas decreases if the volume (V) of the container increases, and vice versa.
        
        In the process of breathing-in, our chest grows slightly and the rib cage gains in size (and volume), and so the air inside our lungs occupy a larger space (volume)
    - - The rate of transfer of molecules or atoms by diffusion through a unit area is proportional to concentration gradient
    - - Applies to gas exchange as the partial pressures for oxygen and carbon dioxide equilibrate across the respiratory membrane
        
        They do so such that PO2 = 100 mmHg and PCO2 = 40 mmHg in the blood after it flows through the lungs
- - - - The fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen
    - - Causes inflammation of the lungs, which causes the patient to have breathing problems
  - - - Bacterial Pneumonia
        
        Causes inflammation of the lungs, which causes the patient to have breathing problems
      - Atmospheric Pressure
        
        The fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen
    - - Lead to respiratory failure and possibly death
      - Cause the inefficient access of oxygen in our blood in order to make our body function properly
  - - - Can invade the heart and cause the death of heart muscle cells
      - develop a major acute cardiac complication
    - - A pneumonia infection can spread from the lungs into the bloodstream
        
        It can reach other major organs and result in organ damage or even death
      - Septic shock can cause very low blood pressure and a reduced blood flow to the body’s major organs
      - The lungs are responsible for adding oxygen to the blood and removing excess carbon dioxide
        
        If they are unable to do this, your major organs can get too much carbon dioxide and not enough oxygen
    - - Weakened immune system due to another condition, like HIV or cancer that’s being treated with chemotherapy, are at a higher risk for developing pneumonia and experiencing complications
      - Fatigue is being experience as the immune system is working really hard to fight off the virus
    - - As the body tries to fight an infection, weakness or muscle soreness may also occur
      - Chills happen when muscles expand and contract
    - - The urinary tract infection can spread and lead to pneumonia
      - Two types of pneumonia-causing bacteria, Streptococcus pneumoniae and Legionella pneumophila, can also be found in the urine
        
        Streptococcus pneumoniae
        
        leading cause of bacterial pneumonia and otitis media (middle ear infections) and an important contributor to bacterial meningitis
        
        Legionella pneumophila
        
        a severe, often lethal, form of pneumonia
    - - Vomiting
      - Nausea
    - - Bluish Skin
        
        Due to the lack of oxygen in the blood, it leads to the skin turning blue
