Normals
What is normal PaCO2
35-45mmHg
What determines the acidity of the blood
the pH
metabolic alkalosis is most determined by what two ABG parameters
pH and HCO3
Why is hypoventilation more severe in REM
respiratory muscles are "paralyzed"
What is normal PaO2
80-100mmHg
When the CO2 goes down, how does this affect the pH
The pH goes up because the blood is less acidic
If a patients CO2 is less than 35 should they increase or decrease their breatging
decrease
A patient falls asleep and his PCO2 is 10mmg higher than it was when he was awake( at 40mmhg) Now it is 50mmHg. What is this guys issue
Hypoventilation
high CO2 = knock out drive to breathe =decreased rate and depth of breathing= hypoventilation
What is percent FiO2 in room air
21%
When the CO2 goes up (Acidic) how does this affect the pH
The pH decreases and becomes more acidic
Kyphoscoliosis is and example of acute or chronic hypoventilation syndrome
chronic
What is normal SpO2
94-100%
If a patient has a CO2 is 54. What is the medical term for his breathing response
Hypercapnia
Head trauma would be considered acute or chronic hypoventilation syndrome
Acute
What is normal pH
7.35-7.45
Giillian Barre and obesity are considered acute or chronic hypoventilation syndromes
Chronic
What is normal Bicarb HCO3
22-26mEq/L
What is normal Hgb
12-16 g/dl
