Anesthesia monitors are an array of sophisticated medical devices used during surgical procedures to continuously track a patient's physiological status while under anesthesia. These monitors provide real-time data crucial for maintaining patient safety and optimizing anesthetic depth. Key parameters typically include continuous electrocardiogram (ECG), non-invasive and invasive blood pressure, pulse oximetry (SpO2), capnography (EtCO2), temperature, and often advanced parameters like neuromuscular blockade monitoring (to assess muscle relaxation), and bispectral index (BIS) or entropy monitoring (to assess depth of anesthesia). Anesthesia monitors provide critical feedback to anesthesiologists, allowing them to precisely adjust medication dosages, manage ventilation, and respond immediately to any adverse physiological changes, thereby ensuring the patient's stability and safety throughout the entire surgical process.
