If your loved one moves with the help of a cane or walker, ensure that the rooms and hallways have enough room for it to be used properly. If your loved one is wheelchair-bound and faces a risk of falling out as a result of weakness, you should use a lap tray (this can be provided by any supplier of medical equipment). If your loved one requires a hospital bed, you must decide to install bed rails in order to prevent them from falling off. If your loved one needs an oxygen concentrator, you must make sure that it is plugged into its own power outlet - you should also make sure that nobody smokes in its vicinity. A bedside commode can be very helpful in reducing trips to the bathroom, particularly at night. A mechanical lift can help with moving your loved one around, particularly if they are heavy. If your loved one will be spending any amount of time alone at home, you should set them up with a medical alert system (e.g. Lifeline), which can alert somebody right away if they are need of urgent help and cannot access the telephone.
Another thing that can help is to have your loved one's eyesight checked out - poor vision, incorrect prescriptions, cataracts and glaucoma can all have an effect on their safety while moving. Any medications that your loved one is taking should also be looked over carefully by a healthcare provider - some medications can cause dizziness and drowsiness, or can affect their balance which is why you need to also have Medical alert for elderly people. Falls cannot be prevented with complete certainty, of course, but ensuring that your home is as secure as it can be will certainly make the task of caring for your loved one easier, along with giving you substantial peace of mind.
