What is a normal urine output in cc/kg/hr?

Normal urine output is an important physiological parameter that can indicate renal function and overall hydration status. Typical urine output in a healthy adult is generally accepted to be around 1 cc (or mL) per kg of body weight per hour. However, it can also be normal to see values closer to 0.5 cc/kg/hr, particularly in specific clinical scenarios such as in patients who are more severely dehydrated or in certain medical conditions.

Choosing 0.5 cc/kg/hr reflects a slightly lower end of the normal range, acknowledging that while 1 cc/kg/hr is ideal, 0.5 cc/kg/hr is still considered acceptable in many settings, especially in cases where patients may be experiencing reduced fluid intake or have increasing bodily demands.

Understanding the context for this output is crucial; values significantly lower than these may indicate potential kidney dysfunction, dehydration, or other pathological conditions that would require further assessment. Therefore, while the ideal target is 1 cc/kg/hr, recognizing 0.5 cc/kg/hr as a normal output helps frame a broader understanding of patient monitoring and care in hyperbaric medicine.
