A Biomedical Engineer’s Guide: Troubleshooting No-Mist Faults in Jet Nebulizers

In respiratory therapy, the jet nebulizer is a cornerstone device, responsible for converting liquid medication into a therapeutic aerosol. Its function is based on a simple but critical engineering principle: the Venturi effect, where compressed air creates a low-pressure zone that draws up and atomizes the medication. However, when a unit fails to produce mist, patient treatment is compromised. This guide provides a systematic, engineering-based approach for biomedical professionals to diagnose and resolve the most common causes of this fault, ensuring equipment reliability and patient safety.

The Hidden Epidemic: Up to 50% of Medical Equipment in Developing Countries is Broken. Here’s How We Fix It.

In the mission to advance global health, we often celebrate the arrival of new medical technologies: the MRI machine, the ventilator, the infant incubator. We must also consider what happens after the ribbon-cutting ceremony. The shocking reality is that in many low- and middle-income countries (LMICs), a staggering percentage of this vital equipment, in some regions as high as 50%, is out of service. This is a systemic failure, resulting in cancelled procedures, delayed diagnoses, and preventable deaths. As our foundational webinar, “Introduction to Medical Equipment

📰 Oxygen Alliance Newsletter: Celebrating Innovation, New Initiatives, and Community Involvement

BME Konza Mobile App We’re excited to share that our BME Konza mobile app has reached a significant milestone, with four versions released internally for testing. This app aims to support biomedical engineers by providing a platform to ask questions, share solutions, and access essential resources such as equipment manuals and maintenance videos. Feedback from internal users, including engineers from OpenO2 and the Global Health Innovation Initiative (GHII), has been invaluable. We are now preparing to test the app externally with engineers from Zambia, Uganda, Kenya,
