Question 1

HCO3

Answer 1

High-alkalotic

Low-acidic

Question 2

BE

Answer 2

High alkalotic

Low acidic

Question 3

CO2

Answer 3

High acidic
Low alkalotic
Changes quickly

Question 4

PO2

Answer 4

COPD won’t have normal O2 levels

Question 5

Compensation vs no compensation

Answer 5

no compensation-change in pH but no change in HCO3/CO2

Question 6

Respiratory alkalosis

Answer 6

High pH, low CO2
Hyperventilation, hypoxia
Corrected with paper bag/pain control, kidneys save acid and dump base

Question 7

Respiratory acidosis

Answer 7

Low pH, high CO2
Obstructive lung disease, over sedan, hypoventilation
Correction-kidneys dump acid save base; narcan, BiPAP/ventilator, tracheostomy, ECMO

Question 8

Metabolic alkalosis

Answer 8

high Ph, High HCO3
Loss of H or gain of HCO3
Loss of HCLfrom stomach, excessive antacids
Correction-electrolyte replacement, diomox/diuretic-takes time!

Question 9

Metabolic acidosis

Answer 9

Low pH, low HCO3
DKA, poisoning, lactic acidosis, diarrhea, kidney disease
Correction-hyperventilation, BiCarb drip

Question 10

Anion Gap

Answer 10

If high-high acid in blood
Low-low protein/electrolytes/lithium
If high, check creatine levels, GFR

Question 11

Obstructive diseases

Answer 11

COPD, bronchiectasis, asthma, bronchitis, emphysema (CBABE)

Hard to get air OUT

Question 12

FVC

Answer 12

if % changed by >10, albuterol works

Question 13

DLCO

Answer 13

Function of capillary membrane
decreased in emphysema, pulmonary hypertension
Treated with amiodarone (side effects are a bitch-brachycardia, interstitial lung disease, thyroid, corneal/cutaneous, hepatic/hypotension)
