Homeostasis: Acid-Base
Description
In this episode we delve into the concept of acid-base balance, exploring its significance in maintaining homeostasis within the body. The discussion covers the roles of the lungs, kidneys, and blood buffers in regulating pH levels, the analysis of arterial blood gases (ABG), and the various types of acid-base imbalances, including respiratory and metabolic acidosis and alkalosis. The episode emphasizes the importance of understanding these concepts for effective patient care and management.
Takeaways
Acid-base balance is crucial for normal cellular function.
The body maintains a specific pH range of 7.35 to 7.45.
Lungs, kidneys, and buffers work together to regulate pH.
ABG analysis provides insight into acid-base status.
Respiratory acidosis occurs when CO2 is retained.
Respiratory alkalosis results from excessive CO2 loss.
Metabolic acidosis can be high or normal anion gap.
Metabolic alkalosis often results from loss of acid.
Understanding these imbalances is key for patient care.
Effective treatment requires addressing the underlying cause.
