Handheld digital spirometer for FVC, SVC, MVV, and MV testing with real-time waveforms, Bluetooth/USB data transfer, and PC software. Ideal for asthma, COPD, and pulmonary function screening. The Global Healthcare Medical GHM-SP90 Spirometer is a handheld, digital device designed for testing pulmonary function and assessing respiratory status. Adopting the differential pressure acquisition principle, the device measures parameters related to Forced Vital Capacity (FVC), Slow Vital Capacity (SVC), Maximum Voluntary Ventilation (MVV), and Minute Ventilation (MV). It displays measurement results and respiratory waveforms on a TFT HD screen, with data upload capabilities for convenient cloud management. The GHM-SP90 is applicable for diagnosis and therapeutic evaluation of lung diseases (such as asthma, COPD, pulmonary fibrosis, and cough), routine physical examination, and more. It can be used in many scenarios, including respiratory medicine, thoracic surgery, anesthesiology, surgery, occupational disease prevention and control institutions, and physical examination institutions. This device is intended for professional use in clinical settings. Not a substitute for professional medical diagnosis.
