  2. Horowitz Index for Lung Function (P/F Ratio) Assesses lung function, particularly in intubated patients. INSTRUCTIONS. The P/F ratio should be used in patients where arterial oxygen partial pressure (PaO 2) and the fractional inspired oxygen (FiO 2) can be measured accurately. Any estimated values should be interpreted with caution. When to Use.

  3. 6 lip 2024 · PaO2/FiO2 ratio is the ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen (FiO2 expressed as a fraction, not a percentage) also known as the Horowitz index, the Carrico index, and (most conveniently) the P/F ratio; at sea level, the normal PaO2/FiO2 ratio is ~ 400-500 mmHg (~55-65 kPa)

    From your film formulation, determine the density of the film. Then estimate the density of the melt : ρm ~ 0.8 ρs. For this example: ρs = 0.919 g/mL. ρm = 0.740 g/mL. We are starting at ~ 500 lbs/hr extruder rate. Output Flow = extruder rate / melt density = 85.7 mL/s.

  7. Steps for Calculating the F Ratio. First, calculate the sum of squares between groups (SS between) which measures the variation among the group means. Then, determine the sum of squares within groups (SS within), indicating the variation due to differences within individual groups.
