A high-quality patient monitor must provide accurate real-time data. You should prioritize the 'Standard 6-parameter' configuration, which includes ECG (Electrocardiogram), HR (Heart Rate), NIBP (Non-invasive Blood Pressure), SpO2 (Oxygen Saturation), RR (Respiration Rate), and TEMP (Temperature). For intensive care units (ICU), ensure the device supports advanced modules such as IBP (Invasive Blood Pressure), EtCO2 (End-tidal CO2), and Cardiac Output (CO). Additionally, check the ST-segment analysis and arrhythmia detection capabilities for cardiac monitoring.
