The M801 Respiratory Mechanics (RM) module is a proprietary solution developed by Witleaf for analyzing patient airway pressure, airflow, and lung volume. It accurately calculates key respiratory parameters such as airway resistance, work of breathing, compliance, tidal volume, and other pressure- and flow-derived metrics. Widely adopted in the integration and development of Class II and III medical devices—including ventilators and patient monitors—the module features dedicated consumables that support adult, pediatric, and neonatal applications, while significantly reducing both usage and maintenance costs in clinical practice.
