Lung function and vascular effects of expert trumpet performance has not been elucidated. Airway mechanics, gas exchange and cardiovascular function were investigated in expert trumpeters during a challenging performance.

Respiratory impedance was measured in expert trumpeters and violinist controls prior to and following performance. Electrocardiography, pulse oximetry, transcutaneous CO₂ and pulse transit time were monitored continuously.

Performance did not alter lung function or gas exchange, except for a reduction in transcutaneous CO₂ in 14 expert trumpeters compared to 4 expert violinists. Heart rate variability and pulse transit time were significantly altered in the trumpeters only, associated with the performance ventilatory requirements with a weight to low frequency band reflecting elevated baroreflex feedback.

Trumpet performance at an expert level does not have an acute effect on airway mechanics and gas exchange was maintained. Repetitive increased intrathoracic pressure during performance resulted in marked heart rate and vagal tone variability. This study reveals the high demands placed on autonomic modulation of the cardiac response to expert trumpet performance.

尚未阐明专家小号演奏对肺功能和血管的影响。在具有挑战性的表演中，专家号手对气道力学、气体交换和心血管功能进行了研究。

在演奏之前和之后，在专家号手和小提琴手控制中测量呼吸阻抗。连续监测心电图、脉搏血氧饱和度、经皮 CO ₂和脉搏传导时间。

除了与 4 名专业小提琴手相比，14 名专业小号手的经皮 CO ₂减少外，表演并没有改变肺功能或气体交换。心率变异性和脉搏传输时间仅在小号手中发生了显着改变，这与性能通气要求相关，重量到低频带反映了压力反射反馈升高。

专家级别的小号演奏不会对气道力学产生严重影响，并且气体交换得以维持。在表演期间反复增加胸内压导致显着的心率和迷走神经张力变异。这项研究揭示了对专家小号演奏的心脏反应的自主调节的高要求。
