The M603 is a four-channel invasive blood pressure (IBP) module, offering the clinical gold standard for hemodynamic monitoring. It supports real-time, synchronized measurement for arterial, venous, and intracranial pressure (ICP) in critical scenarios such as complex surgery, ICU care, and cardiac catheterization. With intelligent algorithm switching between arterial and venous modes and wide-range pressure detection, it delivers accurate, continuous monitoring for diverse clinical needs. As a key vital sign, IBP enables timely assessment of cardiovascular status, guiding treatment and enhancing patient safety in critical care.
