如果不用negative pressure , 就是普通流感类细菌或是病毒传染，什么口罩都可以。不能和武汉病毒比吧。武汉这个和肺结核都需要负压和n95。不知道为什么手术口罩可以，不理解，如果手术口罩可以，为什么给active肺结核病人做手术需要n95，直接手术口罩就可以啦。建议还是n95。而且不是每个人用1860 的n95都可以高度隔绝，脸型，鼻子都会有影响。会有专门公司来测试，都会测个有效过滤值。 Operating Room Patients with suspected or confirmed tuberculosis deemed infectious require Airborne Precautions. Only emergency or medically necessary surgery is performed on a patient with suspected or confirmed infectious tuberculosis disease. Elective operative procedures on patients with tuberculosis should be delayed until the patient is no longer infectious. If at all possible, patients with infectious tuberculosis should be scheduled at the end of the day to limit risk to other patients and healthcare workers. Perform the procedure with a minimal number of personnel. HEPA respirators or N95 respirators are indicated for all persons entering the OR room for respiratory protection. The doors to the OR will be kept closed and the number of personnel allowed in the OR will be kept to a minimum. Tuberculosis patients must be recovered in a negative pressure ventilation room and personnel will follow Airborne Precautions and wear N95 respirators. Patients should then be transported to a negative pressure ventilation room as soon as possible. The patient will have both nose and mouth covered with a regular surgical mask during transport. Personnel performing environmental cleaning and disinfection in the room of a patient who has an infectious airborne disease must use a properly fit tested N95 mask until complete air exchange has been achieved. The period of time required for the ventilation system to achieve a 99.9% air exchange should be noted, for example 21 minutes for a 20 air exchanges per hour cycle. Access to the room should be restricted until the 99.9% air exchange has been completed. 我家孩子12 月因为RSV感染住院，RSV是呼吸道合胞病毒，是传染的，病房门口会有传染病标志。我们住的是斯坦福儿童医院，从ER到ICU再到普通病房，没有任何医护人员戴N95，医生护士来查房的时候，标准装备是发帽，口罩，眼镜，手套和防护服，全都是一次性的，从嵌在走廊墙上的橱子里拿，进屋前穿上，出去时候脱掉扔了。斯坦福医院用的口罩品牌是Halyard, 我拆开看过，有三层，应该是Level 3. 请大家不要因为买不到N95而恐慌。
你看那个seattle的怎么对待就是。不能绝对的比。
前两天收到的通知是如果遇到武汉来的发烧的要穿N95或者CAPR, goggles、gloves、gown。
