"Our company remains dedicated to providing the most effective therapeutic seating devices for wheelchair users." - Steve Kohlman - President

In 1997, Paul Kohlman became ill, resulting in paralysis from the waist down. He was prescribed a ROHO cushion for use in his wheelchair. After only a few weeks of using this cushion, it failed and became completely deflated. Unfortunately for Paul, this popular static air cushion has no way of alerting the user of a cushion leak, and because he had no feeling below the waist, he was not aware of the leak.

In 1997, Paul Kohlman became ill, resulting in paralysis from the waist down. He was prescribed a ROHO cushion for use in his wheelchair. After only a few weeks of using this cushion, it failed and became completely deflated. Unfortunately for Paul, this popular static air cushion has no way of alerting the user of a cushion leak, and because he had no feeling below the waist, he was not aware of the leak. The resulting damage to Paul's skin was a Stage 4 pressure sore in his ischial area. The sore required two flap surgeries to repair the damage and several weeks in bed to allow for healing time. If the ROHO cushion had a low pressure warning device, Paul would have been instantly alerted that the cushion was flat and could have avoided the expensive surgery and painful recovery while confined to bed. It is common knowledge that one of the primary causes of pressure sores for wheelchair users is periods of prolonged sitting time without pressure relief. While there were many different types of wheelchair cushions on the market at the time, there were none that provided automatic pressure relief and a low pressure warning system to instantly alert of the danger of a deflated cushion. To Steve Kohlman, Paul’s son, it was obvious that his father needed a more effective and safer cushion than what had been the industry standard for so many years. Steve decided to try and design a cushion for his father that would provide essential pressure relief and also create a warning system should the cushion ever lose air. After several months of trial and error, the result was the design of an alternating pressure cushion with a built in low-pressure audio and visual alarm. Steve named the cushion the Airpulse PK, in honor of Paul Kohlman. Paul used the Airpulse PK cushion and experienced no further problems with pressure sores. Steve saw an opportunity to help many more wheelchair users with his new design and left his job as an Account Executive for FedEx to start Aquila. The Airpulse PK has been continuously improved since that first model built in 1999, and Aquila now proudly offers the technologically advanced Airpulse PK2 (APK2). The goal is, and has always been, to make it the most effective cushion option for those at the highest risk of pressure sores.
