How to Read ABGs Like a Boss: Master Acid-Base …

18/8/2019· Acid-base ialances are an important concept of nursing practice, not to mention something you’ll need to learn in school. Teachers have different ways to teach students how to interpret ABGs, but here’s my preferred method. What are ABGs? ABG stands for Arterial Blood Gas. You will need to stick an artery to get ABG values. ABGs will include a few different lab values including pH, …

Buffer capacity (video) | Buffer solutions | Khan Academy

Buffer capacity is a property of a buffer and it tells you how much acid or base you can add before the pH starts changing. Basically, as your buffer capacity goes up, which I''m going to abbreviate BC, as your buffer capacity goes up, you can add more of your acid or base before the pH starts changing a lot.
