Here are a couple of suggestions:
"Mia, is product 77622 currently in stock?"
"Do we have any substitute available for CFN 49 49?"
"Has purchase order PO7423 shipped yet?"
"Do you know if CFN 12112 arrived at St. Mary’s Hospital this week?"
"Hey Mia, what cardioplegia vents do we have available right now?"
"When will CFN 4949 be restocked, and how many units are incoming?"
"Can you show me the pressure-flow graph for CFN 77622 and tell me if there are available substitutes?"
