Table 5 The linear CVs of EBSs
From: Changes in bowel sounds of inpatients undergoing general anesthesia
Linear CVs | Calculation methods | Physiological significance |
|---|---|---|
Num_bs | The number of identified effective bowel sounds during the measurement | Frequency of bowel sounds in the 5 min |
Sum_bs | The sum of the absolute values of the identified effective bowel sounds | Reflecting the total energy of the bowel sounds |
Sum_Duration_bs | The sum of the duration of the identified effective bowel sounds | Reflecting the total duration of bowel sounds |
Mean_Duration | The mean of the duration of effective bowel sounds | Mean duration of effective bowel sounds |
Std_Duration | The standard deviation of the duration of effective bowel sounds | Standard deviation of duration of effective bowel sounds |
Mean_Mag_bs | The mean of the mean absolute value of effective bowel sounds | The average energy of effective bowel sounds |
Std_Mag_bs | The standard deviation of the mean absolute value of effective bowel sounds | The standard deviation of the energy of the effective bowel sound |
