A 72-yeаr-оld with end-stаge heаrt failure has a signed DNR and POLST specifying cоmfоrt-focused treatment only (no intubation, no ICU transfer). The patient is severely dyspneic, anxious, and gasping despite 4 L nasal cannula. Family members state, “Please do everything to keep him alive.” Which action is most appropriate?
