The invention relates to a rescue instrument with a function of sleep monitoring. The rescue instrument comprises a circuit board, a radar, a sound collector and a signal generator, wherein the rescue instrument is formed by arranging the radar, the sound collector and the signal generator, which are connected with the circuit board, in a casing; the radar comprises a radar wave generator regularly and intermittently sending broadband and high-frequency radar waves and a radar wave receiver, and can also be a laser radar; independent electrodes, each equipped with an induction coil and a heartbeat sensor, are mounted outside the rescue instrument. The rescue instrument has the advantages that by optimizing the design, the radar or the laser radar is used for sending the radar waves, the sleep condition, the breathing condition and other physiological conditions of a sleeping person are tested without contact with the body, an alarm can be performed, the tester is not interfered, and an unmanned monitoring state is achieved; the independent electrodes with the coils are equivalent to a remote wireless charging manner, are used for monitoring or stimulating a monitored person, or performing heart emergency treatment, and can be used for monitoring conditions including fires, gas leakage and the like.
