Measurement system analysis. A measurement systems analysis (MSA) is a specially designed experiment that seeks to identify the components of variation in the measurement.

PCA: Commonly used abbreviation for patient-controlled analgesia. Analgesia simply means relief of pain. PCA is a method by which the patient controls the amount of pain medicine they receive. There are a number of different PCA systems. In the classic PCA system, the patient receives a preset dose of morphine by pressing a button on a computerized pump that is connected to an IV catheter. With PCA the patient may receive a small continuous flow of morphine and add more morphine as needed to provide a more constant level of comfort.
