心血管性衰竭证据伴心脏指数下降是进行体外膜肺氧合 (ECMO) 支持的指征。[41]Chang B, Crowley M, Campen M, et al. Hantavirus cardiopulmonary syndrome. Semin Respir Crit Care Med. 2007 Apr;28(2):193-200.http://www.ncbi.nlm.nih.gov/pubmed/17458773?tool=bestpractice.com
研究表明,在应用体外膜肺氧合支持治疗后,72% 具有高死亡风险的汉坦病毒心肺综合征患者已存活至出院。[41]Chang B, Crowley M, Campen M, et al. Hantavirus cardiopulmonary syndrome.

提示高死亡风险的特征包括:心脏指数 <2.5 L/min/m²;血清乳酸 >4 mmol/L;心律失常(心室颤动、心动过速或无脉性电活动);补液难治性休克;以及使用血管活性药物治疗。[56]Crowley MR, Katz RW, Kessler R, et al.
