A patient with acute severe heart failure, with a known recoverable underlying etiology can be transiently supported with a mechanical device until native function is recovered. Static stress means that the stress has been applied slowly and is maintained at a steady level. And finally, when failures belong to the wear out zone (ß>1), then a decision has to be made to either run the equipment to failure or develop a proper program for maintenance and overhaul of … Please do not submit your manuscript to the journal as it will not be processed.
