Summary Having trouble solving the total lung capacity?
The spirometer is an instrument that is normally used to measure the flow of air in and out of the lungs under varying conditions. The wet spirometer is based on the simple mechanical principle that air, exhaled from the lungs, will cause displacement of a closed chamber which is partially submerged in water. Basically, it consists of two vessels: a larger vessel containing water and having a breathing hose attached to it; and a smaller vessel inverted and suspended in the water. A counterweight and indicator are attached to the inverted chamber. Air blown into the inverted chamber will cause it to rise, thus moving an indicator arrow, which is calibrated in liters, to give lung volume measurements. In this exercise, you will use the wet spirometer to measure only exhalations. Therefore, all of the inhalation data will be calculated using mathematical relationships.
