Postable Spirometry: User-Assembled Vortex Whistle Spirometer.

Area of Science:

• Biomedical Engineering
• Medical Devices
• Public Health

Background:

• Clinical spirometers are standard for pulmonary function testing but lack accessibility.
• 3D printed vortex whistles offer a more accessible alternative.
• Mailing spirometers to users presents a logistical challenge for widespread adoption.

Purpose of the Study:

• To propose and demonstrate a novel method for mass-deploying pulmonary function tests.
• To investigate the feasibility of creating a spirometer system that can be mailed to individuals.
• To enhance the accessibility of pulmonary function testing through innovative design.

Main Methods:

• Designing and fabricating a vortex whistle spirometer using oilboard material.
• Evaluating the performance of the oilboard-based spirometer.
• Assessing the potential for mass deployment via mail.

Main Results:

• The oilboard vortex whistle maintained performance comparable to standard devices.
• The postcard-based spirometer, termed Postable Spirometry, proved effective.
• The device is suitable for mass deployment and mail delivery.

Conclusions:

• Postable Spirometry offers a ubiquitous solution for pulmonary function testing.
• This approach significantly increases the accessibility of lung health screening.
• The concept can be extended to other smartphone accessories, creating a range of 'Postables'.
