Arterial blood gas (ABG) analysis is a common test ordered in critically ill patients. Often, it is performed very frequently without influencing patient care. Hence, we decided to check the utility of the ABG test in our intensive care unit (ICU).
The data of the previous day ABGs were captured by reviewing the chart in an online pro forma which was filled by the authors. Data relating to patient's details, who ordered ABGs, reason for ordering ABGs, and did the ABG influence patient's management were entered. A total of 985 ABGs were performed in 173 patients for 2 months which was analyzed.
Out of 985 ABGs, in 259 instances (26.29%), interventions were done after reviewing an ABG. The major interventions among these ABGs were ventilator settings adjustment in 134 ABGs (13.6%). A total of 790 ABGs were done routinely with no specific indication (80.20%), while doctors ordered one following an event for 195 ABGs (19.80%).
Our data suggest that 80% of ABG tests were ordered as part of a routine test.

动脉血气（ABG）分析是危重症患者常用的一项检查。通常，该项检查频繁进行，但对患者治疗并无影响。因此，我们决定在重症监护病房（ICU）评估ABG检查的实用性。
通过查看作者填写的在线格式表格中的病历，获取前一日ABG检查的数据。录入患者详细信息、开具ABG检查的人员、开具检查的原因以及ABG检查是否影响患者治疗等相关数据。对173例患者在2个月内进行的985次ABG检查结果进行分析。
在985次ABG检查中，有259例（26.29%）在查看ABG结果后进行了干预。这些检查中主要的干预措施是134次ABG检查（13.6%）调整了呼吸机设置。共有790次ABG检查是常规进行，无明确指征（80.20%），而医生在195次ABG检查（19.80%）中因某一事件后开具了检查。
我们的数据表明，80%的ABG检查是作为常规检查的一部分开具的。
