May support brief postoperative ventilation to spare cardiac work after open-heart surgery; leaves open relevance to contemporary practice.
Does mechanical ventilation reduce the oxygen cost of breathing in patients after open-heart surgery compared to spontaneous breathing?
Prophylactic mechanical ventilation in the immediate postoperative period after cardiac surgery reduces the excessive oxygen cost of breathing and spares cardiac work.
Thung et al. (1963) studied this question.
