We use information systems to assist medical staff with advanced cardiac resuscitation procedures (ACLS). In the past, medical staff would resuscitate patients with cardiac arrest based on their own knowledge and would then need to call back to complete their medical records. Now we use the system to help us, which can instruct all team members to perform their respective tasks and record the entire process in real-time. This information system relieves the stress in high-pressure situations and improves the quality of medical records.
