Full out version on top and quick/cheap version using AMBU bag kit plus filter and hose from breathing circuit - all eBay purchased. Still finishing text instructions/document showing how to make both. Document I post will show top one after all parts have been attached together. Many ways to make these .... all of mine are based on "to-and-fro" design from the old days, which works very well (old pic below).
