Research output: Contribution to journalArticlepeer-review


Lung functions were measured on 13-day-old conjoined thoracopagus twins. Mean values for tidal volume and minute ventilation were 14.8 ml and H2O ml/min for twin A and 12.8 ml and 963 ml/ min for twin B. Functional residual capacities (FRC) were 35 ml/ kg and 39 ml/kg for twins A and B, respectively. Pulmonary compliance and flow resistance for twin A were 2.8 ml/cm II20 and 75 cm H20/liter.sec"1 with 45% of the total work used to overcome elastic resistance. Although values for resistance and work of breathing are within the normal range for studies reported elsewhere, these results tend to be elevated and probably reflect an abnormal state.
