I moved him to my home because he kept falling and breaking bones. The rehab place couldn't even put rails on his bed. Now I have a bed with rails and an alarm under his mattress. He still tries to get up at night and if he makes it - he is on the floor before the alarm can sound.
I know I'm very lucky because he has 12 hour a day care and he's still pretty pleasant but I'm scared he's going to hurt himself again!
As far as Bed Monitors, They have more false alarms so its like the boy that cried wolf. What has been a godsend for me are the IP Camera's ( you can get them online or at Best Buy, Apple store etc. (Tip: Get the one with AUDIO )
You can view on a PC/MAC or a Ipad or similar device. most of the software available has Alarm Settings which are triggered by motion. And you can record the video so if there is a fall, you can watch to see how they fell or just as important , how they landed. I always go back to the video to see where the greatest impact was . ie. Did they hit their head ?
My sister (the idiot) watched her for a few days so I could get a break. She was on the couch not 5 feet from Moms bed. She(the idiot) slept on her GOOD ear! I didn't even know she had a bad one! So Mom fell and yelled for 10 minutes, bleeding.....before the IDIOT woke up. I call this sister the idiot so y'all don't get her confused with my other sister...the selfish, jealous, attention whore, bitch. I just call her bitch for short. Thank God I have 2 wonderful brothers!
After all the reasonable precautions, he eventually tore his bowel when he launched himself out of his geri chair onto his low lying bed.
MIL doesn't remember that she doesn't have the strength to stand up, much less walk. We could see her becoming a bigger and bigger fall risk. Then she fell and broke her hip. Hip is healed, she still can't walk, one of these days it is quite likely she will forget and in just a few seconds, end up breaking something else.
Because falling happens in just seconds, that's what makes it pretty difficult to prevent. Don't obsess (if you were thinking about it:) and don't be unrealistic about what can actually be prevented. Children and elderly people are going to fall, gravity should be blamed, no one else.
