Hi justlearning, welcome to the forum!
In almost all of our apparatus, we have mounted laptops (toughbooks) with evdo connectivity. We use them primarily for dispatching (marking on-scene, cleared from scene, etc...), we also use them to send messages back to dispatch or to send messages to other units. The county has been planning on adding pre-plans, reporting, and GPS data to our MDCs but that is a ways out.
As for PPCRs, we use a product called SafetyPad to enter data. It is a tablet style computer that we cary with us when dealing with patients. We record every detail about the patient as possible. Once at the hospital, we put the safetypad in to a cradle and do our final report. We then bring the safety pad to an ER nurse for their signature and transmit the data to the county for reporting purposes.
Oh, we can also use a USB interface to connect the safety pad to our LifePak 1200 to record EKG information; but that is too technical for our station!
