Tell us about a time when you had to troubleshoot and resolve issues with a medical device.

In my previous role as a Biomedical Engineer, I had to troubleshoot and resolve issues with a medical device. One specific instance was when a patient monitoring device was malfunctioning, causing inaccurate readings. I immediately took action by reviewing the device's specifications and conducting a thorough assessment of the problem. I found that the issue was with the internal sensor calibration. To resolve it, I collaborated with the device manufacturer's technical support team to develop a calibration procedure. I then performed the calibration and validated the accuracy of the readings through extensive testing. The device was back in proper working order, ensuring the patient's vital signs were accurately monitored.

In my previous role as a Senior Biomedical Engineer, I encountered a situation where I had to troubleshoot and resolve issues with a medical device. The device in question was a state-of-the-art MRI machine, and it was encountering intermittent image distortion during scans. To tackle this issue, I first gathered data on the occurrences and analyzed the patterns to identify potential root causes. After extensive research and collaboration with the MRI manufacturer's technical team, I discovered that the issue was related to electromagnetic interference from nearby equipment. I designed and implemented an electromagnetic shielding solution around the MRI machine, effectively eliminating the image distortion problem. To ensure the long-term success of the solution, I also conducted rigorous testing and validation. The result was a significant improvement in image quality and overall performance of the MRI machine, ultimately benefiting patients and healthcare professionals.

During my tenure as a Senior Biomedical Engineer, I faced a complex challenge regarding a life-saving implantable cardiac device. The device was experiencing intermittent and unexpected failures, jeopardizing the lives of patients who depended on it. To address this critical issue, I collaborated with a multidisciplinary team consisting of cardiologists, electrical engineers, and regulatory experts. Together, we conducted an extensive root cause analysis and identified a flaw in the software algorithm that controlled the device's functioning. Leveraging my strong technical knowledge and skills, I proposed a software update that would modify the algorithm and improve device reliability. This proposal involved rigorous testing, risk assessment, and regulatory compliance. After successful implementation, the device failure rate reduced by 90%, ensuring the safety and well-being of countless patients. This experience reinforced the importance of collaboration and the value of interdisciplinary teamwork in the resolution of complex biomedical device issues.
