In order to assess the functional state of the respiratory system, the vital capacity of the lungs is measured using a special device - a spirograph.
Vital capacity (VC) is a value equal to the volume of air that the patient can exhale after taking the deepest possible breath. VC characterizes the state of the external respiration apparatus, allows you to assess the physical development of children and adolescents, to diagnose various diseases.
The procedure for determining the vital capacity of the lungs is called spirography . Manipulation requires the nurse to have knowledge about the device and the principles of operation of the apparatus, as well as the skills of examining patients.
