|Name || |
|Num || |
The number of the Respiration cycle. This number will appear on a primary graph page when validation marks are turned on and the cycle numbers are enabled. When running in a
logging mode other than 1 epoch, the last cycle number will be reported.
| BPM || ||
Breaths Per Minute is calculated from the time interval between Start Inspiration marks.
|TV* || |
Tidal Volume is calculated by multiplying the unscaled TV by the TV Scaling attribute.
The unscaled TV value is obtained by integrating the Rectified EMG signal between the following points: Start Inspiration of the current cycle and Start Inspiration of the following cycle.
| MV* || |
|Minute Ventilation is the product of the TV and BPM. |
| IT || ||
Inspiration Time is the time ion milliseconds between Start Inspiration and Start Expiration marks.
| TT || ||
Total Time is the time in milliseconds between Start Inspiration mark of the current cycle and Start Inspiration mark of the following cycle.
| ET || ||
Expiration Time is the time in milliseconds between Start Expiration and the following Start Inspiration marks.
| TV2* || ||
Tidal Volume is calculated by multiplying the unscaled TV2 by the user-defined TV Scaling attribute.
The unscaled TV2 value is obtained by integrating the Rectified EMG signal between the following points: Start Inspiration and Start Expiration.
| MV2* || ||
Minute Ventilation is the product of the TV2 and BPM.
: dEMG will only provide a partial representation of TV and MV, as it only accounts for diaphragmatic activity. It does not account for intercostal muscles activity or any other activity used during respiration.
