Once you have logged in you will see a scrollable list of play throughs (instruments & procedures) that you have access to.
All the content is available from the PeriopSim servers and needs to be downloaded to your iPad to be used.
A play through is a bundle of content, instruments and instructions to teach you how to recognize and pass the instruments. The play through bundles can be marked in one of three states:
Download - the content is available but a copy has not yet been downloaded to the iPad. If pressed the download will start.
Play - a copy of the content has been downloaded to the iPad and is available for play though.
Update/Play - a copy of the content has been downloaded to the iPad and is available for play though using the right hand side of the button labelled Play. There is, however, an updated version of the content available for download. Pressing the Update on the left hand side of the button will start the download of the changes and will update the local copy to the latest version.
