Stefan Young was the person who brought out the oxygen equipment. He met us at when we arrived home from hospital. Mr Young took the time to explain and demonstrate how to use everything, as well as give us tips and advice on some of the other accessories that are available. Mr. Young was adamant about the safety that needed to be adhered to while using the oxygen, as well as personal stories and danger that the oxygen can create if not adhering to the safety precautions. He was very helpful and informative.
