The world is going through the COVID-19 pandemic, which has high virulence and transmission rate. More significant the viral load during exposure, the greater is the likelihood of contracting a severe disease. Healthcare workers (HCWs) involved in airway care of COVID-19 patients are at high risk of getting exposed to large viral loads during aerosol-generating actions such as coughing or sneezing by the patient or during procedures such as bag-mask ventilation, intubation, extubation, and nebulization. This viral load exposure to airway caregivers decreases considerably with the use of an aerosol box during intubation. The safety tent proposed in this article is useful in limiting the viral load that HCWs are exposed to during airway procedures. Its role can be expanded beyond just intubation to protect against all aerosol-generating actions and procedures involving the patient's airway.
世界正在经历新冠疫情，新冠病毒具有高毒性和高传播率。暴露期间病毒载量越高，感染重症疾病的可能性就越大。参与新冠患者气道护理的医护人员在诸如患者咳嗽或打喷嚏等产生气溶胶的行为期间，或在诸如面罩通气、插管、拔管和雾化等操作过程中，面临接触大量病毒载量的高风险。在插管过程中使用气溶胶盒可大幅降低气道护理人员接触的这种病毒载量。本文提出的安全帐篷有助于限制医护人员在气道操作过程中接触的病毒载量。其作用可扩展到不仅仅是插管，还能防范涉及患者气道的所有产生气溶胶的行为和操作。
