Dan Simmons, respiratory therapist at the Bond Center, was doing a routine check of a portable oxygen concentrator at a patient's home when he noticed that she was faint in color. He checked her oxygen saturation and her heart rate, both were uncharacteristic for someone who had only gotten up to answer the door. Dan thought that perhaps it was his pulse oximeter that was not accurate. After testing it on himself, the oximeter was proven to be correct. He then rechecked the patient, and with no change, he immediately contacted the patient's physician and asked for a verbal order to increase the patient's oxygen levels.

Dan continued to monitor her oxygen and heart rate, recording the values every 10 minutes. And while getting her cylinder ready for transport to the hospital, he discovered that all three backup tanks were empty. Dan then contacted dispatch supervisor Wayne Breaz, who then had delivery technician Rob Montague at the patient's house with the cylinder in less than 20 minutes. The patient was then transported to the hospital.

Later that evening, Dan received a phone call from the patient's husband, thanking him for saving his wife's life. The ER physician explained to the husband that if it weren't for Dan's intervening, his wife wouldn't have been alive when he got home.
