Stretch the protector over the good arm first to see how it fits. If the Dry Pro is too tight, trim along the lines at the appropriate opening. Be careful no to trim too much, make sure a snug, flush fit is maintained around the arm.

Stretch the protector over the PICC line area until the site is completely covered, plus an additional inch on either side. The top and bottom opening should be smooth against the skin. Be carefull of fingernails or sharp objects that could puncture the protector.

Continuously press the pump until all the air is evacuated and the pump becomes flat. Move your arm around and make sure the seal remains intact, then remove the pump and put the cap on. After creating the vacuum seal, observe the Dry Pro for about 5 minutes before going into the water.  In order to remove the Dry Pro simply slide your fingers under the top cuff to let the air in and slide it off.
