Continuous Cardiac Output Catheters | 合法醫療器材資訊網

Noninvasive CCO systems include transthoracic electrical bioimpedance, [4,5][1]suprasternal continuous-wave Doppler ultrasonography, [6]and transcutaneous continuous-wave ultrasonic Doppler. [7,8][2]Although studies have suggested limited accuracy of these devices in clinical use, Thangathurai et al. [9]noted improved performance of the recent thoracic bioimpedance device. Continuous, invasive methods include transesophageal Doppler, [10,11][3]transtracheal Doppler, [12,13][4]transesophageal Doppler echocardiography, [14]and automated border detection. [15]The Baxter CCO catheter has comparable accuracy compared with standard thermodilution CO in stable surgical and critically ill patients. [16-22][5]Its reliability has been questioned with cold-fluid infusion, [23]after hypothermic cardiopulmonary bypass, [24]and in postreperfusion of liver transplantation. [25]Response time delays of 5-7 min have been show...
