氧疗的方式及升级的时机

Oxygen therapy and time to upgrade the oxygen therapy

低氧血症是多种危重症的常见表现之一,氧疗是改善低氧血症最有效的治疗,若选择不合适的氧疗方式或延误升级氧疗的时机,可能造成细胞及组织持续缺氧、功能障碍甚至器官衰竭。当氧疗开始后,需要严密观察患者临床症状、体征、指脉氧饱和度、血气分析等多种指标,并充分利用近年来新兴的呼吸速率氧合指数、改良呼吸速率氧合指数、VOX指数、列线图模型及在线计算器等多种工具综合评定患者氧合动态变化,及时调整氧疗方式及参数,以改善患者预后。

Hypoxemia is a common manifestation of many critical illnesses,and oxygen therapy is the most effective treatment for improving hypoxemia.Choosing inappropriate oxygen therapy or delaying the timing of upgrading oxygen therapy may result in persistent cellular and tissue hypoxia,functional impairment,and even organ dysfunction.After starting oxygen therapy,it is necessary to closely observe various indicators such as clinical symptoms,physical signs,pulse oxygen saturation,blood gas analysis,and make full use of various tools such as the respiratory rate oxygenation index,modified respiratory rate oxygenation index,VOX index,L-line diagram model,and online calculators to comprehensively assess the patient′s oxygenation dynamically as well as timely adjust the oxygen therapy mode and parameters to improve patient prognosis.
