Bullets&Bandages p.16 explains the capabilities of medkits quite well:
"Published Shadowrun materials describe a number of systems that can deliver autonomous medical care using a variety of different terms: medkit, autodoc, stabilization unit, and more. All of these describe different medical expert systems and/or computers that analyze medical data and direct patient care. Medical expert systems generally fall into two categories. A medkit, as the name implies, is a kit that contains medical supplies as well as a medical expert system. Medkits can operate autonomously in a limited role by monitoring a patient’s biometric status, giving medications, administering gases, and more, but they often require a metahuman operator for hands-on tasks. An autodoc, on the other hand, is a medical expert system built on a more functional drone platform that is usually self-propelled and generally includes robotic appendages With these added features, an autodoc can perform a more robust range of hands-on tasks and is designed to function independently from a metahuman operator."
