My father who has a c5/c6 spinal cord injury moved in with me about a year ago. He has been calling me using Siri. However, he now has to use a CPAP machine (full mask) and is unable to remove the mask himself. I am looking for a home wireless paging system that he will be able to activate. He can move his arms a little and can let his hands fall on his chest. I tried out a few wireless systems from amazon but he didn?t have the strength to activate the push button. When he was in an inpatient therapy hospital he was able to activate a paddle type pager. However, I haven?t been able to find one online. Does anyone have any suggestions?
