Our Dad is in heart failure. He had trouble relaxing, Marilee came in and showed him how to use the oxygen by breathing in through his nose and exhaling through his mouth. Thanks to her our Dad is finally breathing easy without panicking. She took the time to listen and understand what he was saying and took the time to show him how to use oxygen to relax. The first time he really relaxed in 40 days! Wish someone had showed them this method sooner. He is a happier patient and easier for us to deal with. Thank you Marilee! You are a prayer answered.
