• Heart rate (electrodes placed on the chest)
• Leg movements (electrodes placed on the legs)
• Breathing (breathing sensor placed near the nose and mouth)
• Breathing effort (two small elastic belts placed around chest and abdomen)
• Oxygen level (small sensor attached to the finger)
• Audio and Video Recording
