Serum Osmolality - What Is the Osmolarity of Your Plasma?

Explore the concept of serum osmolality in this 25-minute video lecture from Medicosis Perfectionalis. Delve into the differences between osmolality and osmolarity, learn how to measure serum osmolality, and understand its clinical significance. Discover the effects of water efflux, dehydration versus volume depletion, and the relationship between osmolality and tonicity. Examine measured versus calculated osmolality, the impact of glucose and sodium levels, and the concept of remote plasma tonicity. Gain insights into effective osmotic solutions, the osmolality gap, and various clinical applications. Engage with quiz questions, mnemonics, and practical examples to reinforce your understanding of this crucial physiological parameter.
