肺心病患者容易发生呼吸肌疲劳,可导致呼吸衰竭。锻炼呼吸肌增强其肌力和耐力,对预防呼吸肌疲劳而引起的呼吸衰竭很有帮助。呼吸肌锻炼还可以改善肺功能,加大呼吸幅度,有助于提高肺泡通气量,提高血氧饱和度。呼吸肌锻炼包括腹式呼吸、缩唇呼吸和全身性呼吸体操锻炼。 Patients with pulmonary heart disease prone to respiratory muscle fatigue, can lead to respiratory failure. Exercise respiratory muscle enhance their strength and endurance, to prevent respiratory muscle fatigue caused by respiratory failure helpful. Respiratory muscle exercise can also improve lung function, increase breathing rate, help to improve alveolar ventilation, improve blood oxygen saturation. Respiratory muscle exercises include abdominal breathing, reduced-lip breathing and general breathing exercises.
