COPD 2 forms

Chronic Bronchitis
Emphysema

2

Chronic Bronchitis

Build up of goblet cells along the lining of the airway

Spending your life irritating your lungs (smoking, work)

Keep building those goblet cells!!! FULL OF MUCOUS

3

Emphysema

Loss of elasticity in the lungs
Breathe in no problem
No elastic recoil of alveoli

Add breath...

More air in alveoli than in their mouth

Negative pressure resources

Smaller airways shut = air trapped

4

Breathe in...

Diaphragm down
Intercostals out
Air is pulled in

5

Exhale..

Alveoli collapsing w/ elasticity forcing air out

6

Emphysema CO2 is usually

Low because they breathe so fast, PEEP themselves

7

Chronic hypoxemia you develop

polycthemia - makes blood heavy increasing the work load on heart (Cor Pulmonale)

8

Tx for asthma/COPD

Position of comfort
>90% for asthma
@ 90% for COPD
SABA

9

What is SABA

Short acting beta adrenergic

Beta 2 - Increased RR and bronchodilate

10

Problem with SABA

Will have Beta 1 stimulation as well

11

Drugs that don't affect Beta 1 as much

Anticholinergic (Atrovnet)
