70 Y/O female viral infection of lungs, pneumonia, difficulty breathing,…

- - - - allow for expansion
        and recoil
    - - 3 lobes on
        right side
      - 2 lobes on
        left side
  - - - Type 1 alveolar cell
        
        main structure of alveoli
      - type 2 alveolar cell
        
        Produce surfactant
        
        reduce surface tension &
        prevent lung collapse
      - macrophages
        
        protect against infection
- - - - P1V1=P2V2
        
        as volume increases,
        pressure decreases & vice versa
    - - Gases act independently
        of each other
    - - solubility for each gas is different
  - - - shortness of breath
      - pain
      - dizziness
  - - - 160mmHg
        
        as atmospheric pressure decreases,
        partial pressure of O2 decreases
    - - 760mmHg
    - - 633mmHg
    - - 133mmHg
  - - - CO2 dropped off &
        O2 picked up by hemoglobin
- - - - increased capacity to deliver oxygen
        
        corrects effects of high altitude
- - - - viral takeover
  - - - blood becomes sludge
