The invention discloses an information interaction method for a network hospital first aid service. The information interaction method includes the steps that a cloud server is connected with detection equipment and a medical institution terminal; the detection equipment collects physiological parameters and compares the physiological parameters with a safety threshold range; when the physiological parameters are not within the safety threshold range, the detection equipment outputs data to the cloud server; when receiving the data output by the detection equipment, the cloud server sends the data to the medical institution terminal. The invention further discloses an information interaction system for the network hospital first aid service. The information interaction system and method for the network hospital first aid service enable medical appointment to be intelligent, and further improve the timeliness and effectiveness of medical appointment information interaction.
