Cards

Term
What do all metabolic process require?
Definition

Normal acid-base range

7.35- 7.45

Term
Explain Acid Base Balance
Definition
  1. Metabolic process require normal range
  2. Balance is reflected by PH
  3. PH is determined by number of acids and bases in blood

 

Term
What is the Equation for Acid Base Balance
Definition

HCO3- H+= H2CO3=CO2+H20

Bicarbonate + Hydrogen = Carbonic Acid= Carbonic acid is weak it falls apart to from Carbon dioxide and H20

 

Increase in H= move toward Carbonic

Decrease in C02= move other way

Term
What does body do to maintain Hemostasis to maintain acid base balance?
Definition

K+ exchange for H+ to reduce acidity

Lungs- release C02 in acoditic state and retain C02 in alkaline state

Kidney increase/decrease H+ or HC03- secretion.

If you get acidic body hangs on to H+ if you get alkalinic body will dumb HC03 into urine

Term
Respiratory Inbalances are?
Definition

Acidosis-Excess of C02/ ineffective respiration

Alkalosis- Decreased C02/ excessive respirations

Term
Metabolic Imbalances
Definition

Acidosis- increased levels acid H+ and/ or decreased bicarb levels... have to have even number of bicarb and acid. ex... excessive metablic activity and or renal failure

Alkalosis- decrease H+ or increased Bicarb... ex metabolic loss of acids or gain of alkalinity d/t responce to drug overdose

Term

Normal Lab Values

Where are these gases found?

 

  • PH
  • Paco2
  • HC03
Definition

Ph- 7.35- 7.45

Paco2- 35-45= partical pressure of C02

HC03- 22-26

 

Found in arterial blood.... IT HAS NOTHING TO DO WITH VENOUS BLOOD.

Term
What works to adjust PH balance
Definition

Lungs blow off c02 or retain

Kidney adjust Bicarb and H+ion

Term

How to interperite Arterial blood gases

Acid or Base?

Resp or Meta?

Definition

Acidosis=low ph

Alkalosis= high ph

Resp= PaCO2 change

Met HCO3- change

Term

Interpreting ABGs

 

Definition

  Acidosis        Alkalosis

PH     7.2   7.40   7.6

 C02(lungs)     60   40   20

Metabolic(kidneys) 18   24   30

 

 

 

What ever is on same side of ac/alk is how you name

C02 and Met work op to try and resolve problem

Term
Does 02 have anything to do with Acidosis?
Definition
NO
Term
When does compensation occure
Definition
When PH is returned to normal
Term
Who would have a PH that is almost normal but everything else out of aline
Definition
Compansates Resp Acidosis= C02 patients... CO2 person will never have a normal blood gas.
