Study Notes

Acid-Base Balance Purpose

Maintains optimal pH levels in bodily fluids, crucial for cellular functions and metabolic processes.
Enables efficient functioning of enzymes and biochemical reactions by stabilizing hydrogen ion concentrations.

Regulatory System

The renal system primarily regulates acid-base balance through excretion of hydrogen ions and reabsorption of bicarbonate.
The respiratory system also plays a key role by adjusting carbon dioxide levels, which affects blood pH.

Consequences of Imbalance

Acid-base imbalances can lead to severe health issues, including acidosis (excess acidity) or alkalosis (excess alkalinity).
Symptoms may include confusion, fatigue, and disturbances in heart rhythms, potentially leading to life-threatening complications.

Assessment Methods

Arterial blood gas (ABG) analysis is a common method used to assess acid-base balance.
ABG measures pH, carbon dioxide, and bicarbonate levels in the blood to determine the acid-base status.

Excessive Acidity Condition

Metabolic acidosis can result from excessive acid accumulation in the body due to conditions like kidney failure, diabetic ketoacidosis, or severe dehydration.
This condition can lead to life-threatening complications if not addressed promptly.
