并发高碳酸血症的呼吸衰竭疾病,以不同方式影响呼吸肌。导致呼吸肌疲劳和衰竭的主要的非神经性因素,是呼吸功增加、机械性障碍、神经肌肉疾病营养不良、休克、低氧血症、酸中毒、钾镁和无机磷缺乏。人类呼吸肌可分为两组:吸气肌—胸锁乳突肌和斜角肌,膈肌和肋间外肌;呼气肌—肋间内肌和腹肌。 Concomitant hypercapnia in respiratory failure affects respiratory muscles in different ways. The major non-neurogenic factors that cause respiratory muscle fatigue and failure are increased respiratory work, mechanical disorders, malnutrition in neuromuscular diseases, shock, hypoxemia, acidosis, potassium magnesium and inorganic phosphorous deficiency. Human respiratory muscles can be divided into two groups: inspiratory muscle - sternocleidomastoid and scalene, diaphragm and intercostal muscles; exhalation - intercostal and abdominal muscles.
