V/Q Decoded

Such an excellent app for understanding the intricacies of ventilation/ perfusion. With its accurate graphics it helps decode the mechanics behind pathologies associated with ventilation/ perfusion. Thank you sir for creating this wonderful app.

VP relations

V/Q relationship is at the very essence of life, and its disturbance is central to respiratory failure and support. This app simplifies this complex concept beautifully. Its simplicity and brilliant design make it an excellent teaching tool.

FAQ

What is SBD V/Q used for?

SBD V/Q is an interactive teaching cartoon designed to illustrate ventilation-perfusion (V/Q) mismatch in the lungs. It helps users understand how air (V) and blood flow (Q) interact and the implications for respiratory support.

Is SBD V/Q a medical device?

No, SBD V/Q is strictly for educational use only. It is not a medical device and should not be used to diagnose, treat, monitor, or make decisions about ventilation for real patients.

What concepts does SBD V/Q teach?

The app teaches about V/Q mismatch, including matched units where blue blood turns red, shunt where blood remains blue due to lack of air, and dead space with air but no blood. It also covers hypoxemic versus hypercapnic failure.

Can I adjust parameters in SBD V/Q?

Yes, you can drag parameters like the A-a gradient and FiO2 to observe their effects. The app shows how raising oxygen helps low V/Q but has less impact on true shunt.

What devices is SBD V/Q available on?

SBD V/Q is available for iPhone and iPad, making it accessible for users on Apple's mobile platforms.

How often is SBD V/Q updated?

The app was last updated on October 6, 2026, with version 1.0. This indicates it is a relatively new release, and future updates may follow based on user feedback and development.

Does SBD V/Q have ads?

No, SBD V/Q does not contain advertisements. It is a free application without any ad interruptions.

What is the age rating for SBD V/Q?

SBD V/Q has an age rating of 4+, making it suitable for a wide audience, including younger learners interested in the basic concepts of respiratory function.
