Title: Preliminary study to identify severe from moderate cases of COVID-19 using NLR&RDW-SD combination parameter Document date: 2020_4_14
ID: jecsj3xw_8
Snippet: The clinical standards for the identification of moderate and severe patients are as follows: 1) moderate, with fever, respiratory track symptoms and pneumonia imaging; 2) severe, having any of the following conditions beside the symptoms and sign of moderate: a) respiratory distress, RR ≥30 times/minute; b) oxygen saturation ≤93% under rest state; c) arterial blood oxygen partial pressure (PaO2)/oxygen concentration (FiO2) ≤300mmHg and d) .....
