Hello any medical related students or professionals here?? I’ve been having a hard time understanding this one can someone explain it step by step and in a “dumb way” because ive been watching it on youtube and they dont really explain it comprehensively

I know this because my wife has a “frozen diaphragm”, meaning it doesn’t move.
The muscle we call the diaphragm is actually 2 despatch muscles, each referred to as a hemi diaphragm.
Diaphragmatic excursion is simply the AMOUNT of movement each hemi diaphragm makes during a breath. From relaxed position to full lungs.
The diaphragms are kinda curved upwards in a hemispherical shape when relaxed. To breathe in, the muscle tightens, becomes shorter. This flattens the muscle. The excursion is the distance traveled by the top of the curve to flat.
