"Liters Per Minute" (LPM) is a unit of measurement that indicates the flow rate of a liquid or gas. It tells us how many liters of a substance pass through a specific point in one minute. This measurement is commonly used in various fields, including medicine, engineering, and environmental science, to assess the efficiency of systems like pumps, engines, and respiratory devices. For example, in a medical context, the flow rate of oxygen delivered to a patient may be measured in LPM. Understanding LPM helps ensure that the right amount of fluid or gas is being delivered for optimal performance and safety in different applications, such as oxygen therapy or industrial processes.
