I'm not at all familiar with infant PFTs, but I am a self proclaimed math guru so here is what I can gather from your daughters test results.
First I'll look at the FEV 0.5 because that is what I am most familiar with. In adults they test the FEV1, which is the volume of air expelled during the first second of expiration. (we take a big deep breath in and then blast it out as forceful as possible for 6 seconds during our adult test) So my assumption is, somehow, during and infant test they measure a similar volume of air (in mL, not Liters) during the first half second of expiration after filling the lungs with air.
Based on the percentage predicted it seems a baby with your daughters length and age can be expected to expel 180mL of air during the first half second of the test. It looks like she expelled 220mL, which was more than expected. So her FEV 0.5 is 122% (or 220mL). If I'm reading the results correctly, that is fantastic and she has above normal "lung capacity". (more than 100%)
I hope this helps.
