目的探讨急性冠脉综合征合并低氧血症的患者应用无创机械通气治疗进行干预的时机.方法2014年7月至2015年7月在昆明医科大学附属延安医院诊断为急性冠脉综合征合并低氧血症的患者46例,使用面罩供氧后,脉搏血氧饱和度仍然持续下降至≤90%时,给予经口鼻面罩进行双水平气道正压通气(Bi Level)治疗,观察机械通气前和通气2 h后呼吸频率、脉搏血氧饱和度、动脉血气分析等指标的变化.结果 46例急性冠脉综合征合并低氧血症的患者,给予无创机械通气治疗2 h后,呼吸频率、脉搏血氧饱和度、动脉血氧分压均有明显改善,临床症状缓解明显.结论急性冠脉综合征合并低氧血症的患者,在使用面罩供氧后,脉搏血氧饱和度仍然持续下降至≤90%,出现呼吸衰竭时,开始应用无创机械通气治疗,能够安全、迅速地纠正低氧血症和呼吸衰竭.
Objective To investigate the timing of intervention with noninvasive mechanical ventilation in patients with acute coronary syndrome complicated with hypoxemia.Methods From July 2014 to July 2015, Yan-An Hospital Affiliated to Kunming Medical University was diagnosed as having acute coronary syndrome Oxygenmia in 46 patients, the use of mask oxygen, pulse oximetry continued to decline to ≤ 90%, given nasal mask bi-level positive airway pressure (Bi Level) treatment to observe the mechanical ventilation Respiratory rate, pulse oximetry and arterial blood gas analysis were performed before and 2 h after ventilation.Results In 46 patients with acute coronary syndrome complicated with hypoxemia, after 2 h of non-invasive mechanical ventilation, the respiratory rate , Pulse oximetry and arterial partial pressure of oxygen were significantly improved and clinical symptoms were relieved.Conclusion The patients with acute coronary syndrome complicated with hypoxemia still maintained pulse oximetry after using oxygen mask Decreased to ≤ 90%, respiratory failure occurs, the application of non-invasive mechanical ventilation began to be treated, can safely and quickly correct hypoxemia and respiratory failure.
