Table 1 Classification of diaphragm motion
Classification
Definition
Normal motionThe amplitude of diaphragmatic excursion is > 4 mm, and the difference of amplitude between the hemidiaphragms is < 50%
Decreased motionThe amplitude of diaphragmatic excursion is ≤ 4 mm and the difference of amplitude is > 50%
Absent motionAbsent motion is considered by a flat line trace
Paradoxical motionParadoxical motion is considered when diaphragm moves away from the transducer in inspiration
