The systolic, diastolic, and the mean arterial systemic blood pressure decreased after thoracotomy (by -12%). The systolic, diastolic, and the mean pulmonary arterial pressure showed an immediate decrease (by 25%). The central venous pressure was not changed. The cardiac output (HMV) and the stroke volume could not be measured before the thoracotomy. However, the HMV (+17%), the HMV-index (+30%), and the stroke volume (+60%) increased from the 10th to the 30th min after the thoracotomy. The heart rate decreased continuously (by -19%). The maximum rate of pressure rise (dp/dtmax) increased primarily insignificantly and decreased afterwards (by -10%). The quotient dp/dt/p decreased immediately (by -10%). All measures were carried out until the 30th min after thoracotomy.
开胸术后，收缩压、舒张压和平均动脉系统血压下降（下降了12%）。收缩压、舒张压和平均肺动脉压立即下降（下降了25%）。中心静脉压未发生变化。开胸术前无法测量心输出量（HMV）和每搏输出量。然而，开胸术后第10分钟至第30分钟，心输出量（HMV）增加了17%，心输出量指数增加了30%，每搏输出量增加了60%。心率持续下降（下降了19%）。最大压力上升速率（dp/dtmax）起初无显著增加，随后下降（下降了10%）。dp/dt/p比值立即下降（下降了10%）。所有测量均在开胸术后第30分钟前进行。
