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.
To observe experimentally, record and/or calculate forced expiratory volume (FEV) and maximal voluntary ventilation (MVV).
To compare the observed values of FEV with predicted normals.
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.
Breathe normally for three complete respiratory cycles.
Inhale as deeply as they can and hold their breath for an instant.
Exhale as quickly and completely as they can.
Resume normal breathing for three cycles.
Breathe normally for five complete cycles.
Breathe quickly and deeply for 12-15 seconds.
Return to normal breathing for 5 more cycles.
Extremely easy to setup and record the data.
The transducer is hand-held, lightweight and very easy to use.
Hygiene and safety: The system comes with disposable bacterial filters and mouthpieces, or reusable mouthpieces can be used.
The transducer has a removable head for sterilization.
The software automates the setup procedure for the student. There are no knobs and dials to confuse them.
Once the system is calibrated, a group of students can record data without re-calibrating.
On-screen commands prompt the students throughout the lesson.
BIOPAC’s Simple Sensors warn students if they plug the wrong device or transducer into the system.
The lesson will also work as part of a group study.
Student accessory packs of mouthpieces, bacterial filters, nose clips, electrodes and abrasive pads are available.
BSL Instructor’s Guide provides lab tips and lesson options.
BSL Answer Guide is included on the installation disc.
