RLE and PLE Tools
The RLE Tool uses the ratio of the relevant respiration response and the comparison respiration response to produce a suggested respiration score. When the examiner selects a relevant question, the RLE tool compares the relevant respiration response to all comparison questions on the chart and then displays the R/C score(s). If a score meets or exceeds a recommended threshold, the score is displayed and the circular node will be colored accordingly. To use the RLE tool, simply click on the RQ in the question bar while viewing a chart, and read the RLE score and recommendation icon at the CQ that is chosen for comparison. Note: the software will not choose the CQ for the examiner. The examiner, based on their expertise, must choose the appropriate CQ for comparison. Below is a summary/representation of the various node colors:
 |
+1 | CQ respiration line excursion length is sufficiently shorter than the RQ length |
 |
-1 | RQ respiration line excursion length is sufficiently shorter than the CQ length |
 |
0 | There is an insufficient difference between the RQ and CQ length |
 |
The difference between the RQ and CQ length is too extreme |

There are two common methods of comparing Relevant Questions to Comparison Questions: to the left CQ, or to bracketing CQs. With either method, the first step is to inspect the evaluation window and a few seconds prior to it to make sure that the data is not unstable or artifacted. If it is, then do not evaluate this segment regardless of the recommendation made by the RLE Tool.
Below, the recommended score for the thoracic (upper) respiration tracing is zero (0), because the node is white. The recommended score for the abdominal (lower) respiration tracing is zero (0), because, once again the node is white. Next, collapse the two scores into one representative score to put into the scoresheet. Since both are zero (0), then the representative score for respiration, would be zero (0).
Below, the recommended score for the thoracic (upper) respiration tracing is minus one (-1), because the node is red. The recommended score for the abdominal (lower) respiration tracing is minus one (-1), because, once again the node is red. Next, collapse the two scores into one representative score to put into the scoresheet. Since both are minus one (-1), then the representative score for respiration, would be minus (-1).
Below, the recommended score for the thoracic (upper) respiration tracing is minus one (-1), because the node is red. The recommended score for the abdominal (lower) respiration tracing is zero (0), because, the node is white. Next, collapse the two scores into one representative score to put into the scoresheet. The representative score for respiration, would be minus (-1).
Below, the value of the thoracic (upper) respiration tracing exceeds the optimization threshold, because the node is gray. After visual confirmation, if there is an artifact, the representative score for this tracing would be Ø. If there is no visual artifact, score this tracing zero (0).
Additionally, the recommended score for the abdominal (lower) respiration tracing is plus one (+1), because the node is green. The combined respiration score would be either Ø (if an artifact is present) or plus one (+1) if an artifact is not observed.
For each CQ, the first step is to determine the integer score for each respiration tracing by selecting the recommended integer from the comparison question for each of the upper and lower respiration tracings. It is possible that the thoracic and abdominal respiration tracings may be scored to different comparison questions for the same relevant question.
Following that step, the thoracic and abdominal scores are combined into one respiration score and entered onto the scoresheet.
