The Dependence of Oxygen Uptake on Oxygen Delivery in the Adult Respiratory Distress Syndrome1–4

摘要: The relationship between delivery and uptake of O2 was evaluated in 20 patients with the adult respiratory distress syndrome (ARDS). Eleven were studied acutely, after progressive increments positive end-expiratory pressure. remaining 9 underwent serial determinations gas exchange during several days, because varied secondary to changes clinical status or therapeutic interventions. In all but one patient, decreasing led similar decreases O2. general, mixed-venous PO2 variable had no consistent relation cardiac output delivery. a contrasting group 12 without ARDS, not related, correlated well output. We conclude that there is direct Changes may reflect delivery, output, adequacy o...
