Pleural effusion is a medical condition where there is an unusual amount of fluid around the lungs. It is often linked to patients with cancer, pneumonia, tuberculosis, autoimmune conditions, and those with heart, liver, and kidney diseases. Current diagnosis methods are either invasive or radiation-heavy, and there is also no way to monitor pleural effusions outside a hospital. Monitoring this information in a timely manner can lead to reductions in hospitalization time and costs. SensoriumLab makes a user-friendly and non-invasive diagnostic system for pleural effusion. Patients can be monitored remotely, even by non-professionals. The system uses electromagnetic waves to detect pleural fluid, and provides information that could help a doctor decide medical treatment—automatically sending alerts when the pleural fluid volume is high.
