ABGs

This set of flashcards covers key terms and concepts related to Arterial Blood Gas (ABG) interpretation and treatment from the lecture notes.

Acidosis

A condition where the pH level is below 7.35.

Alkalosis

A condition where the pH level is above 7.45.

Normal pH range

The normal range of pH in the body is between 7.35 and 7.45.

Uncompensated ABG

A status where the pH remains abnormal and either CO2 or HCO3 is normal.

Partially compensated ABG

A status where the pH is not normal and the abnormal value does not match the pH.

Compensated ABG

A status where the pH is normal, but the value (CO2 or HCO3) is abnormal.

Pulmonary compensation

The lungs compensate for metabolic disturbances by changing CO2 excretion.

Renal compensation

The kidneys adjust bicarbonate retention and H+ secretion to compensate for respiratory disturbances.

Metabolic Acidosis treatment

Involves using NaHCO3 IV in small amounts to prevent metabolic alkalosis.

Respiratory Acidosis treatment

May involve stimulating the patient and adjusting ventilator settings.

Respiratory Alkalosis treatment

Often treated by rebreathing CO2 using a paper bag or rebreathing mask.

Normal pCO2 range

Normal pCO2 levels are between 35 and 45 mmHg.

Normal HCO3 range

Normal HCO3 levels range from 22 to 26 mEq/L.

CO2 in acidosis

In acidosis, the CO2 level is typically high, indicating an attempt to compensate.

HCO3 in alkalosis

In alkalosis, the HCO3 level is typically elevated.

pH dividing line

A pH of 7.40 is the dividing line between acidotic and alkalotic.
