L13 Pulmonary Function II

BSL pulmonary function lesson
This BSL Pulmonary Function lesson demonstrates how to record and analyze Forced Vital Capacity, Forced Expiratory Volume (FEV 1,2,3) and Maximal Voluntary Ventilation (MVV), and builds on the principles established in L12 Pulmonary Function. Students will perform two tasks in order to record their data, and then they will compare their results with other students in the group and with published normal values for specified height, weight and age.
  • Great introduction to Pulmonary flow studies.
  • Automatically calculates values for FEV and MVV.
  • Uses a clinical grid for easy interpretation of the data.

Experimental Objectives

  1. To observe experimentally, record and/or calculate forced expiratory volume (FEV) and maximal voluntary ventilation (MVV).

  2. To compare the observed values of FEV with predicted normals.

  3. To compare MVV values with others in your class.

Tasks Performed by the Student

BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.

With new developments happening daily, it’s easy to forget to slow down and take a breath. Breathing can be as forgettable as it is crucial; the often forgettable automatic function inspires rituals in religions around the world. Studies have shown the importance of breathing not just in a spiritual sense but also in physiological health benefits. Lung functionality […]
