Allen's Test
|
A test to assess for collateral circulation to the hand by evaluating the patency of the radial and ulnar arteries.

|
Compensation
(When is it implemented?) (How do you know when it is in affect?) |
Compensation refers to the body processes that occur to counterbalance an Acid-Base disturbance.
When compensation has occured, the pH WILL BE WITHIN NORMAL LIMITS (7.35-7.45) |

|
Metabolic Acidosis
(What is it?) (Results from?) |
MA is a total concentration of buffer base that is lower than normal.
Results from: 1. Loss of buffer base or retention of too many acids w/o sufficient bases 2. Renal failure 3. Diabetic ketoacidosis 4. Production of lactic acid 5. Ingestion of toxins (aspirin) |
|
|
Metabolic Alkalosis
(Results from?) |
Results from:
1. Hypovolemia 2. The loss of gastric fluid 3. Excessive bicarbonate intake 4. Massive transfusion of whole blood 5. Hyperaldosteronism |
|
|
Respiratory Acidosis
(Results from?) |
Caused by primary defects in the function of the lungs or by changes in normal respiratory patterns as a result of secondary problems.
Any condition that causes an obstruction of the airway or depresses respiration status can cause respiratory acidosis. |
|
|
Respiratory Alkalosis
(Results from?) |
This occurs in conditions that cause overstimulation of the respiratory system.

Regulatory Systems for Hydrogen Ion Concentration in the Blood
|
1. Buffers
a. Hemoglobin System b. Plasma Protein System c. Carbonic Acid-Bicarbonate System d. Phosphate Buffer System 2. Lungs 3. Kidnesy 4. Potassium Exchange |

Normal Arterial Blood Gas Values
|
pH = 7.35 - 7.45
Pco2 = 35 - 45 mm Hg HCO3 = 22 - 27 mEq/L Po2 = 80 - 100 mm Hg |
