Subclavian catheter insertion
A lot of fallacies are taught in universities.
Forty years ago, I studied anesthesiology for 24 months.
Teachers at that time were saying you cannot insert a subclavian catheter through a Venflon sheath.
Of course, it is obvious the plastic tubing collapses with pleural movements.
Nobody was giving a second thought that if there is no movement, then the J-wire comes through.
As for instance holding breathing, or in an anesthetized patient.
