Narrative:

Mid way through the flight; the captain noticed a low hydraulic level 2 message on the EICAS. We reviewed the procedure for it; and discussed what our actions would be should we lose pressure and the entire hydraulic system as per the procedure for loss of hydraulic system 1 or 2. As we monitored the fluid quantity; we saw the quantity was decreasing. After reaching a quantity of zero; we noticed the pressure began to gradually drop. It was not until checking in with approach that we lost all pressure to hydraulic system 2. At this time we declared an emergency with approach control. The captain made the landing without any incident or difficulties. And we were able to taxi to the gate under our own power. The captain did an excellent job of managing threats by briefing well ahead of time what we would do in case of a loss of hydraulics in system 2. We kept everyone in the loop including dispatch; flight attendant; and ATC when appropriate. Because we discussed as a crew what our actions would be well in advance of the hydraulic system failure; we were able to easily manage a normally high workload phase of flight. I learned a lot from the captain's leadership and forward thinking. I will be sure to incorporate this in my flying by taking action and thinking ahead of the aircraft to manage threats before they happen.

Title: An EMB-145 EICAS alerted LOW HYD LEVEL 2 at cruise so crew briefed emergency procedures in advance of the arrival and when the quantity indicated zero; declared an emergency and completed the approach well prepared for any eventuality.
