CPAP Hose Holder for Bed - Adjustable CPAP Hose Hanger with 360° Rotation - Tangle-Free CPAP Tube Support Pole for CPAP Hoses - Essential CPAP Accessories

You're welcome, I've helped more than a few parents with their children's titrations/modes and sleep setups in past, the hose hanger I will link to is able to telescope out of the ring that holds the hose (using a stretch cord) so that the hose can move down from the position (unlike the one you're using), it will help him: https://www.amazon.com/dp/B0B4RL3BMY That's the one I use too :)
