Patient transport apparatus with crash detection

A patient transport apparatus comprising:

• a support structure comprising a base, a support frame, and a patient support deck defining a patient support surface to support a patient;
• an inertial sensor coupled to the support structure and configured to generate a signal representing a change in velocity of the support structure;
• a controller in communication with the inertial sensor and comprising a processor and a non-transitory storage medium having stored thereon a program that, when executed by the processor, is configured to:
• monitor the signal generated by the inertial sensor for changes relative to a predetermined threshold, and
• in response to an event in which the signal exceeds the predetermined threshold, the program is further configured to:
• generate a waveform based on the signal received from the inertial sensor;
• store the waveform at an overwritable address in the non-transitory storage medium;
• and
• generate an entry in an event log stored in the non-transitory storage medium, the entry comprising one or more parameters associated with the waveform.
