Analysis of arterial blood gas for 110 patients with acute respiratory stress syndrome

Objective To explore the significance of dynamic determination of arterial blood gas for early diagnosis,treatment and prognosis of patients with acute respiratory stress syndrome(ARDS). Methods The results of 700 times arterial blood gas assayed in 110 patients with ARDS were analysed retrospectively. Results (1)Types of acid-basic disturbance; The simply acid-base disturbances were 41 cases, Complex acid-base disturbances were 53 cases, Triple acid-base disturbances were 16cases. (2)The oxygenation indexes of all 110 patients were less than 26.7kpa. (3) The cured rate in 110 cases was 50 and the mortality was 60. Conclusions dynamic determination of arterial blood gas and calculation of oxygenation were of important clinical value in diagnosis and treatment of ARDS.
