The Ambulatory Lung Diagnostic System (ALDS) is a two-in-one device designed to perform both Airway Oscillometry and Forced Spirometry. This innovative system leverages a cloud-based algorithm to analyze test results, integrating clinical outcome parameters with patient history to deliver a clear physiological interpretation of lung function for healthcare providers. The system algorithm identifies obstructive and restrictive patterns, helping clinicians detect and understand corresponding respiratory limitations. Engineered for mobility, durability, and efficiency, the ALDS supports high patient throughput with each test typically taking just a few minutes. By combining both diagnostic methods in daily diagnostic routines, the ALDS offers a comprehensive, multidimensional assessment of lung function, enhancing pulmonary diagnostics.
