Application of Respiratory Support Nursing Based on Circulation Monitoring in Acute Respiratory Distress Syndrome

目的：探讨基于循环监测的呼吸支持护理对急性呼吸窘迫综合征(ARDS)患者的呼吸功能、循环功能及预后的影响，为临床护理提供科学依据。方法：采用简单随机抽样的方法，选取2023年2月至2024年11月住院治疗的70例ARDS患者为研究对象，随机分为观察组和对照组，每组35例。对照组接受常规呼吸支持护理，观察组在此基础上实施基于循环监测的呼吸支持护理。对两组患者的氧合指数(PaO2/FiO2)、中心静脉压(CVP)、心输出量(CO)、机械通气时间及ICU住院时间等指标进行比较，并记录并发症发生情况。结果：观察组患者的氧合指数显著高于对照组(150.32 ± 20.45 vs. 140.56 ± 19.87, P Objective: To explore the influence of respiratory support nursing based on circulatory monitoring on respiratory function, circulatory function and prognosis of patients with acute respiratory distress syndrome (ARDS), and to provide scientific basis for clinical nursing. Methods: Using simple random sampling method, 70 ARDS patients hospitalized from February 2023 to November 2024 were selected as the research object, and randomly divided into observation group and control group, with 35 cases in each group. The control group received routine respiratory support nursing, while the observation group received respiratory support nursing based on circulation monitoring. The oxygenation index (PaO2/FiO2), central venous pressure (CVP), cardiac output (CO), mechanical ventilation time and ICU hospitalization time were compared between the two groups, and the complications were recorded. Results: The oxygenation index of patients in the observation group was significantly higher than that in the control group (150.32 20.45 vs.140.56 19.87, P < 0.05), and CVP and CO were significantly better than those in the control group (CVP: 11.15 1.96 vs. 12.34 1.88 mmHg, P < 0.05; CO: 5.48 ± 0.42 vs. 4.21 ± 0.46 L/min, P < 0.05). The time of mechanical ventilation (7.12 2.03 days vs. 9.01 ± 2.15 days, P < 0.05) and ICU stay (10.24 2.92 days vs. 12.87 ± 3.11 days, P < 0.05) in the observation group were significantly shorter than those in the control group. No serious complications occurred in both groups. Conclusion: Respiratory support nursing based on circulatory monitoring can significantly improve respiratory function and circulatory state of ARDS patients, shorten mechanical ventilation and ICU hospitalization time, and has good safety, which is suitable for clinical promotion.
