What is a patient simulator used for?

• A. To deliver patient medications automatically
• B. To mimic patient signals for testing medical devices
• C. To sterilize medical equipment
• D. To store patient data

Answer: (B)

The main idea is that a patient simulator creates realistic physiological signals so medical devices can be tested and validated without a real patient. By mimicking heart rhythms, blood pressure, breathing, and other signals, it lets technicians check that monitors, ventilators, defibrillators, and other equipment respond correctly, trigger alarms appropriately, and stay calibrated under different conditions. You can program scenarios from stable readings to dangerous variations to ensure devices perform safely in real-life situations. It’s not used to deliver medications, sterilize equipment, or store patient data.
