Measure Vital Capacity |
This set is the simplest and least expensive tool we know of to measure vital capacity, which is the volume of air a person can expel after taking the deepest possible breath. This set can also be used to compare effects of height, age, physical activity, and smoking. It includes four heavy-gauge plastic bags calibrated to six liters, four holders, and four mouthpieces.
