Educational Pearls
- Poiseuille's Law addresses the flow of a fluid through a tube.
- Many common ED presentations involve alterations in flow: asthma, MI, ischemic stroke, etc.
- According to the law, flow increases with the 4th power of the radius. That is to say, doubling the radius of the tube will increase the flow by 16x.
- Therefore, in situations that require re-opening of an anatomic tube (artery, airway), small changes in the size of the opening will result in dramatic effects.
