12-inch patient monitor is a medical device used to continuously track vital signs in adult, pediatric, and neonatal patients, featuring a 12-inch or 12.1-inch color TFT display that shows key parameters like ECG, blood pressure (NIBP), oxygen saturation (SpO2), pulse rate, respiratory rate (RESP), and temperature (TEMP). These monitors are typically portable, have built-in rechargeable batteries, and offer features such as touch screen operation, data storage, alarm systems, and optional modules for advanced monitoring like EtCO2 and IBP, as well as central monitoring system connectivity and thermal printing.
