“…Small amounts of air may not produce detectable changes in the heart sounds but only produce .electrocardiographic abnormalities ( MICHENFELDER 1968). Recently a Swan-Ganz catheter was used for pulmonary artery pressure monitoring in a case of air embolism during posterior fossa surgery (MUNSON et al 1975). Its application was introduced by MARTIN (1968) and evaluated by MICHEN-FELDER et al (196913).…”

“…4 An increase in PAP is indeed one of the earliest signs of air embolism and the degree of pulmonary hypertension has been shown to be proportional to its severity. [5][6][7] During the first minutes of rapid blood transfusion, PAP and PCWP increased simultaneously, without any improvement in systemic blood pressure. These phenomena are often observed during rapid blood transfusion and probably result from transient depression of the myocardium by the citrate in the blood.…”

“…The former implies the need for continuous and accurate recording of arterial pressure and in the majority of centres (87%) measurement of intra-arterial pressure is used routinely. A variety of techniques is available for the early detection of venous air embolism, including the Doppler ultrasonic probe, measurement of end-tidal carbon dioxide concentration and, most recently, measurement of pulmonary artery pressure (PAP) using a flowdirected catheter (Maroon, Edmonds-Seal and Campbell, 1969;Brechner and Bethune, 1971;Munson et al, 1975). The insertion of a right atrial catheter is common practice and enables the anaesthetist to confirm the entry of air into the heart and, on occasions, to aspirate significant quantities of air.…”
