Periodic breathing may be observed in patients with severe congestive heart failure during exercise. We describe a patient with such a breathing pattern. We noted that nadir of oxygen consumption cycles slightly preceded the nadir of ventilation cycles, suggesting that this breathing pattern is due to cardiac output periodic changes, possibly through an interplay among the two ventricles and the pulmonary blood reservoir.
重度充血性心力衰竭患者在运动期间可能会出现周期性呼吸。我们描述了一位有这种呼吸模式的患者。我们注意到,耗氧量周期的最低点略先于通气周期的最低点,这表明这种呼吸模式是由于心输出量的周期性变化所致,可能是通过两个心室与肺血容量之间的相互作用引起的。
