Introduced here are approaches for capturing and recording medical event details during cardiopulmonary resuscitation (CPR) events and other emergency medical events. A recording begins when an operator inputs a request to initiate recording. The operator may use a recording system with a combination of input devices to record medical actions. The recording system acknowledges the operator's actions by various means which may include icons displayed for the operator. The operator's interactions with the icons indicate corresponding actions observed by the operator, which are recorded as a log of the actions in temporal order that serves as a non-transient record of the medical event. An analysis of the recorded details of the medical event, by comparing the actions to prescribed actions in one or more professional standards, can provide an assessment of the actions taken.
