Abstract:
Point of care ultrasound (POCUS) is a portable and accessible tool that has immense potential in low- and middle-income countries (LMIC) for diagnostic accuracy and medical education. We implemented a hybrid in-person and virtual training curriculum to teach providers in Belize the basic techniques of lung ultrasound in the diagnosis of pneumonia. Between August 2021 and June 2022, a total of eleven lung scans were performed at Hillside Clinic for patients presenting with respiratory complaints. Deidentified images were shared via the ButterflyIQ web platform to POCUS experts in the United States. We found that training was solidified through virtual, immediate feedback using the common interfaces Butterfly iQ + and WhatsApp to share images and guide diagnostic reasoning. The aim of this review study is to share our experience and challenges in the implementation of a POCUS training curriculum in an LMIC, provide an example of training methodology that can be effective, and discuss how this can be implemented and modified for clinicians in similar settings.

Virtual Work
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
Effects of feedback
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...
Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
