Q

In Obstructive lung disease

Airflow obstruction can be related to 4 things:

A
  1. Retained or excessive secretions
  2. Inflammation of mucosal linings of airway walls
  3. Bronchial constriction:
    1. ​tone
    2. spasm
    3. size
    4. inflammation
  4. Weakening of support structure or alveoli

Q

PFT Test

Normal vs. Obstructive

Break it down!!!

A
  • Normal: Example
    • ​FEV1= 3.0L
    • FVC (tot. air we breathe OUT)= 4.0L
    • FEV1/FVC= 75% (Nrml is .70)
  • Obstructive: example
    • ​FEV1= 1.0L (cant get air OUT)
    • FVC= 4.0L
    • FEV1/FVC= 25% (LOW bc cant get air OUT)
      • ​Obstructive Dis.=
      • **As FEV1/FVC shrinks==> MORE severe OLD***

COPD: MSK Component

Sequela #1:

Talks about EXPIRATION

A
  • Anatomically Barrel Shaped diaphragm—> ​
    • ​CLASSIC S/S—> ribs now angled out horiz.
  • Diaphragm pulled to flat pos.—>
  • Length-tension relationship changes—>
  • Exhalation now active or forced—->
    • ​remember should be passive
  • Leads to excessive fatigue + caloric use—->
    • ​using mm’s not norm. active
    • all energy goes to breathing
    • these people DO NOT eat
  • Excess abd. pressure==> urinary incontinence

A
  • End-stage dev. of R. Sided HF from Pulm HTN
83
Q

88
Q

CF

Pathophysiology

What is the CFTR Gene?

A

CF Transmembrane Conductance Regulator Protein

  • gene loc’d on chromosome 7 that creates abnorms in CFTR PRO
    • ​this CFTR PRO usually provides a channel by which Na+/Cl- can pass thru epithelial cells
  • SO…gene mutations cause lack of (or malformed) CFTR
89
Q

What is another good way to remember the CFTR PRO?

A

Where sodium goes, H2O follows!!!

Na + Cl live together

*w/ malformed CFTR PRO—> now mucus cannot get hydrated (to thin out)==> Thicccc mucus that cannot get coughed out!!!

90
Q

    • Impaired cilia function
    • bronchial obstruction by lg mucus
    • Hyperinflation
    • atelectasis
