Intake and Output Measurements

Why measure I & O?  Measuring and recording all liquid intake and output during a 24-hour period helps to complete the assessment data base for fluid and electrolyte balance

Dehydration  An excessive loss of water from the body tissues.  Dehydration disturbs the balance of essential electrolytes: K+, Na+, Cl-  Causes: ________  An excessive loss of water from the body tissues.  Dehydration disturbs the balance of essential electrolytes: K+, Na+, Cl-  Causes: ________

Overhydration  Marked by an excess of water in the extracellular fluid.  Is a symptom of liver, renal, or cardiovascular disease  2 types:  Hypervolemia  Edema  Marked by an excess of water in the extracellular fluid.  Is a symptom of liver, renal, or cardiovascular disease  2 types:  Hypervolemia  Edema
