One can predict acute lung injury

Health Care, Medicine, Social Health Community 977 Comments

The lung injury prediction score (LIPS) should be used to predict patients who are unlikely to develop ALI/ARDS.

  • LIPS >4 predicts ALI with a sensitivity and specificity of 69 and 78 %, respectively.
  • LIPS <4 has a negative predictive value of 97%.
