Defibrillators and other such tools
You can imagine what would happen if $Deity forbid, a senior Microsoft official were laid out on a pavement with the Medics in attendance. So they were stood around fiddling with their Life-Saving equipment, neglecting the patient. "FFS don't just stand there, DO something" say a group of passers-by. A medic breaks off from concentrating to reply "We are - we're just waiting for Windows 10 to install and then we'll be right with him."
