Study Notes
Acid-Base Balance
- Bicarbonate is a crucial buffer in the blood, regulating pH levels.
- The kidneys play a vital role in reabsorbing and producing bicarbonate.
- Imbalances in acid-base regulation lead to four major types of acid-base disorders.
Fluid Volume Excess
- Inspecting the jugular veins can help assess fluid volume.
- If veins are visible more than 3 cm above the sternal angle, it suggests excess fluid volume.
- Albumin, a plasma protein, contributes to maintaining blood volume through colloid osmotic pressure.
- Normal albumin levels range from 3.5 to 5.5 g/dL.
- The body compensates for fluid volume excess by increasing sodium and water excretion and reducing ADH production.
Buffer Systems
- Blood buffers work in pairs to maintain normal pH levels.
- These buffers act like sponges, absorbing hydrogen ions to neutralize acidity.
