A Simple Respiratory Guide for Respiratory Therapy in the Trauma Patient
Abstract
The respiratory index (R.I.), P(AaDO-2)P(aO2) was investigated in 177 intubated patients. An R.I. of 0.1-0.37 is normal. An R.I. of two or greater was an indication for intubation, and over six was associated with a 12% probability of survival. The R.I. reflects the presence of pulmonary shunting in a variety of circumstances including atelectasis, pulmonary contusion or pulmonary emboli. A nomogram which allows one to follow the course of the patient with respiratory problems is described. Movement along the same isobars or between isobars can be followed by plotting the P(aO2) against the F(IO2). Thus, the rationale and effect of respiratory therapeutic manipulations may be graphically recorded.
