16
Q

Acidemia vs. acidosis (same with alkalosis and alkalemia()

A

Acidemia - blood pH below normal range

Acidosis - process that lowers ECF pH

17
Q

Metabolic acidosis/alka

A

Changes serum HCO3 concentrations and pH

18
Q

Metabolic acid/alk response

A

Respiratory response moving pCO2 in same direction as HCO3 change

19
Q

Respiratory acid/alk

A

CHanges arterial CO2 and pH

20
Q

Respiratory response

A

Initial - Change in HCO3 by buffering

Later - Renal response changing HCO3 in same direction of pCO2

21
Q

Met acid - cause and response

A

cause - HCO3 dec

Resp - pCO2 dec via resp

22
Q

Resp acidosis cause and resp

A

cause - pCO2 inc
Acute - HCO3 inc via buffer
Chronic - HCO3 inc via renal

23
Q

Met alkalosis - cause and response

A

Cause - HCO3 inc

Resp - pCO2 in via resp

24
Q

Resp alkalosis - cause and response

A

Cause - pCO2 dec
Acute - HCO3 dec via buffer
Chronic - HCO3 dec via renal

25
hyperventaltion incdicates
metabolic acidosis
26
Deeper, slower breaths indicates
Metabolic alkalosis
27
Initial diagnosis
Serum electorlyters (HCO3)
28
Definitive diagnosis
Serum pH and pCO2
29
Essential to collect
Patient hisotry
30
Vomiting causes
Metabolic alkalosis
31
Hypovolemia (what is it and what does it cause)
Low volume from diarrhea | Lactic acidosis
32
Aspirin poisoning
Acidosis
33
SID
Strong ion difference | Cation - anion
34
Decrease in SID difference causes
acidosis
35
Mechanism of SID changing pH
POsitive charges must equal negative...body compensates by increasing H+ ions
36
Hyperchloremic acidosis
Caused often from fluid resusciation
37
How to avoid SID changes
Ringer's/Hartmann's solutions Ringers - bicarb Hartmann's - lactate Replaces Cl with something else
