Fig. 4From: Prediction of mechanical ventilation greater than 24 hours in critically ill obstetric patients: ten years of data from a tertiary teaching hospital in mainland ChinaNomogram for prolonged mechanical ventilation using the independent prognostic factors critically ill obstetric patients. For example: If a patient was with AKI, myocardial injury, estimated blood loss of 3.91 L, and PaO2/FiO2 of 250 mmHg. The scores were 4, 4, 2.5 and 3.5, respectively. Then the total score was 14 and the probability of PMV was approximately 93%Back to article page
