🏃 Índice de actividad Duke (DASI)
UsoWhen to use: functional capacity / some preoperative discussions without CPET.
Estratificación<4 METs often flags limited capacity in perioperative conversations.
LímitesWhen not to use: as replacement for indicated CPET/stress testing. · Pitfall: over-reporting unusual peak efforts. · Language/culture may affect item interpretation.
