text: The officers attached to the unit each undertook a four-week course in pre-hospital care, funded by TfL. TfL estimated that around one third of delays on the London Underground were caused by "passenger incidents", of which the majority related to medical problems with passengers; the purpose of the unit is to provide a faster response to medical incidents, providing treatment at the scene with the aim of reducing disruption to the network.
