A twin-tube breathing system for inhalational anaesthesia in dental surgery is described. The system is a modification of a parallel Mapleson 'A' breathing system and is suitable for use with continuous flow anaesthetic machines. Resistance to airflow has been evaluated and is within the recommended ranges at all flows likely to be experienced in normal clinical conditions. The system is suitable for children and adults, easy to use and efficient. The expiratory valve is located remote from the face and the system is suitable for scavenging by active, assisted or passive systems.
本文描述了一种用于牙科手术吸入麻醉的双管呼吸系统。该系统是对平行Mapleson 'A'呼吸系统的改进，适用于连续流麻醉机。已对气流阻力进行评估，在正常临床条件下可能遇到的所有流量下，其阻力均在推荐范围内。该系统适用于儿童和成人，使用方便且效率高。呼气阀远离面部，该系统适用于主动、辅助或被动系统进行废气清除。
