FOYERTANS

FOYERTANS physical health index calculation: VFOYERTANS includes calculations for the following physical indicators: 1: BMI（Body Mass Index） BMI=weight ÷ square of height (weight in kilograms; height in meters) 2: The formula for calculating glomerular filtration rate is: body weight (kg) × (140 age)/72 × serum creatinine value (mg/L) 3: Lung compliance Pulmonary compliance=VT/(Pplat PEEP) VT (tidal volume): ml Pplat (suction platform pressure): cmH2O PEEP (Positive End Respiratory Pressure): cmH2O The normal range of lung compliance indicators is 50-100ml/cmH2O. Pulmonary compliance is sensitive for early diagnosis of small airway diseases, and decreased pulmonary compliance is commonly seen in pneumonia, pulmonary edema, atelectasis, and pneumothorax
