Poorly ventilated indoor spaces pose a risk for airborne transmission of SARS-CoV-2. We measured carbon dioxide levels in a multiple areas in an acute care hospital to assess the adequacy of ventilation. Carbon dioxide levels remained below 800 parts per million in most areas but exceeded this level in a small conference room with 8 occupants, an office with 3 occupants, and a bathroom with 2 occupants. Measuring carbon dioxide levels could provide a simple means for healthcare facilities to assess the adequacy of ventilation.
通风不良的室内空间存在 SARS-CoV-2 空气传播的风险。我们测量了一家急症医院多个区域的二氧化碳水平，以评估通风是否充足。大多数区域的二氧化碳水平仍保持在 800ppm 以下，但在一个容纳 8 人的小会议室、一个容纳 3 人的办公室和一个容纳 2 人的浴室，二氧化碳水平超过了这一水平。测量二氧化碳水平可以为医疗机构提供一种简单的方法来评估通风是否充足。
