@Lilly, diabetesmine actually raised that question a bit ago, here is what they said:

"Leftover Powder – I was also very worried about seeing some residual white powder left in the cartridge after most doses: was all the insulin really getting into me?

But Boss [Sanofi Senior Medical Director] reassures us that a little leftover powder in a used cartridge should not cause concern. The manufacturers [of] Afrezza cartridge[s] don’t expect 100% absorption, which is also the case with injected insulin, he says. “It’s OK if about 8% still seems to be in the cartridge afterwards. That’s calculated in. You lose some in the mouth, some in the cartridge. It’s such a fine powder that most of it absorbs in the lungs.”

He’s been on the road for that entire time, so BG has been a bit wacky and we are not in the “testing” phase exactly. Just aiming for “adequately managed” presently. Anyhow, he had an unfortunate morning today - at a conference with a super carb-a-riffic breakfast option, he decided he’d just eat the pastries and fruit on offer, so he loaded up an 8u Afrezza…
