Bone Marrow Aspiration and Biopsy? There's an app for that
This app is clearly for professional doctors, not diletantes like myself, but 80 minutes of video plus plenty of images and diagrams make this quite a steal.
Apparently there are quite a few of these sorts of apps out there but this one is apparently the cheapest and uses the best clip art.
Here’s a video for your edification, but if you don’t think you need this app, you probably don’t.
