Regulation of <strong>Fluid</strong> Output<br />
• Hormonal control<br />
– 1 Antidiuretic hormone (ADH) [neurohypophysis]<br />
– 2 Aldosterone [adrenal cortex]<br />
– 3 Atrial natriuretic peptide (ANP) [heart atrial walls]<br />
• Causes of physiologic fluid im<strong>balance</strong>s<br />
– Dehydration: ↓ blood pressure, ↓ GFR<br />
– Overhydration: ↑ blood pressure, ↑ GFR<br />
– Hyperventilation - water loss through lungs<br />
– Vomit<strong>in</strong>g & Diarrhea - excessive water loss<br />
– Fever - heavy perspiration<br />
– exudat<strong>in</strong>g Burns, contusion - fluid loss<br />
– Hemorrhage – if blood loss is severe
