Interactive Lab Exercises
Labs are interactive work areas that encourage students to compare and contrast
scenarios, adjust model parameters, and see results. The Disease States
Lab encourages students to compare spirogram tracings, compliance curves,
and expiratory flow rates for normal, obstructive, and restrictive pulmonary
diseases. Students may use a question bank to focus their exploration. The
Statics Lab enables students to specify a patient's lung volume and glottis
state. The resulting lung and chest-wall recoil pressures are depicted using
illustrations, graphs and equations.
Objective: User will be able to interactively change ventilatory variables, inspired oxygen, and introduce values typical of various pathologic conditions to see their effect on blood gas concentrations.
- Topics:
- Effects of ventilation
- Imbalance
- Diffusion
- Shunt
- Cardiac Output
- Hemoglobin
- VQ Mismatch
Estimated time to complete lab when used in conjunction with the on-line user guide: 2 hours
Objective: User will be able to identify the spirometer tracings, compliance
curves, and expiratory flow rates of patients with obstructive, and restrictive
diseases.
- Topics:
- Obstructive disorders
- Restrictive disorders
- Spirometer tracings
- Compliance curves
- Expiratory flow rate
Estimated time to complete tutorial: 20 minutes
Objective: Users will be able to demonstrate the relationship between chest
wall and lung recoil at various percentages of total lung capacity.
- Topics:
- Static pressures
- Chest recoil
- Lung recoil
Estimated time to complete tutorial: 10 minutes
