Excerpt

Several indices exist to monitor adequate oxygenation, but no such index exists for ventilatory efficiency. The ventilatory ratio (VR) is a simple tool to monitor changes in ventilatory efficiency using variables commonly measured at the bedside [1]:

VR = \frac{{\dot{V}}_{E_{m e a s u r e d}} \times P_{a_{c o_{2 m e a s u r e d}}}}{{\dot{V}}_{E_{p r e d i c t e d}} \times P_{a_{c o_{2 p r e d i c t e d}}}}
