心脑血管病患者为何不宜深呼吸?问:我是一名心脑血管病患者,平时我总喜欢练习胸式或腹式深呼吸运动。可是医生却说:心脑血管病患者不宜做深呼吸锻炼。请问这是为什么?答:研究发现,强烈的深呼吸可使血管狭窄50%~66%,使大脑、心脏、肾脏等重要脏器的血流量减少75%~80%。因此,虽然深呼吸增加了氧气的摄入,血液含氧量也明显增加,但组织器官的供氧量却显著减少。组织缺氧会刺激中枢神经,进一步使呼吸加深加快,形成恶
Why should not patients with cardiovascular disease take a deep breath? Q: I am a cardio-cerebral vascular disease patient. Usually I always like to practice chest or abdominal deep breathing exercise. However, the doctor said: Cardiovascular and cerebrovascular disease should not do deep breathing exercise. A: The study found that a strong deep breath can stenosis of blood vessels 50% to 66%, so that the brain, heart, kidneys and other vital organs blood flow decreased by 75% to 80%. Thus, while deep breathing increases oxygen intake and blood oxygen levels increase significantly, oxygen supply to tissues and organs is significantly reduced. Hypoxia tissue will stimulate the central nervous system, to further deepen the respiration, the formation of evil
