1982年Arafat、Mina和AL-Zahir三个中暑治疗中心对233例热射病人作了血气分析。在开始降温、清洁气道并用面罩吸入28%氧气时抽取动脉血、立即用血气分析仪在37℃下进行分析。结果233例中有40%病人的动脉血氧含量为15 ml/dl或少于此数。这种较低的血氧含量可以用氧张力来解释。30%病人有贫血,血红蛋白浓度为10%,甚至更低。使Hb不饱和的另一个因素是高热和酸中毒引起的氧合血红蛋白解离曲线右移。
In 1982, three heat stroke treatment centers in Arafat, Mina and Al-Zahir made blood gas analysis of 233 patients with thermal radiation. Arterial blood was drawn at the start of cooling, cleaning the airway and inhaling 28% oxygen with a mask, and immediately analyzed with a blood gas analyzer at 37 ° C. Results Of 233 patients, 40% of patients had arterial oxygen levels of 15 ml / dl or less. This lower oxygen level can be explained by oxygen tension. 30% of patients have anemia, hemoglobin concentration of 10%, or even lower. Another factor that saturates Hb is the right shift of the oxyhemoglobin dissociation curve caused by hyperthermia and acidosis.
