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.

📰 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,
Oxygen Conservation and Management During Health Emergencies
Systems for delivering oxygen play a critical role in deciding how patients receive oxygen therapy and are essential to conservation initiatives. Low-flow and high-flow systems are the two general categories into which these systems fall. Low-flow devices, like simple face masks, non-rebreather face masks and nasal prongs, deliver oxygen at a rate lower than the patient’s total respiratory requirements, conserving oxygen while meeting patient needs. High-flow devices, such as high-flow nasal cannulas, are essential for patients in critical respiratory distress because they deliver a larger volume
The journey of oxygen, from its creation to reaching patients.
In medicine, medical oxygen plays a role in respiratory treatments and critical care. Besides highlighting the importance of sustainable oxygen therapy ecosystems, the global impact of the COVID 19 pandemic exposed weaknesses in our supply chains and infrastructure. In this article, we explore the process involved in delivering oxygen to patients focusing on the logistical challenges heightened by the pandemic. Medical oxygen is produced using a number of methods and procedures. The main technique for creating oxygen is through air separation. Purifying the air through the
