Noisy new air mattress disrupting sleep cycle circadian rhythm. Any thoughts on this?

maybe I don't understand but why would the air turn on, isn't it a mattress with air already pumped and sealed in it?  then if that is the case why is the air pump kicking on?  hope someone else can explain

Imho, perhaps there is a flaw in this air mattress, e.g. a bed/mattress is supposed to be akin to a quiet setting to get restorative sleep.

I had to get a topper. If you cannot return it, research toppers.

I’m inclined to agree with Grandma1954 that you will get used to it. When I first went off to college our dorm heating would come on in the early hours of the morning. I am not exaggerating to say it sounded like someone was inside of it banging on the metal with a hammer as hard as they could! Everyone complained bitterly about it. But after about a month most of us slept through it. Also, I grew up in Ga with the noisy nights of insects and frogs. I loved it. But, when my DH’s family arrived from the UK for our wedding, they all slept very badly because it was so noise at night! I think if it is a “normal” noise your brain eventually accepts it and blocks it out. Perversely when I moved to the UK I found it very difficult to sleep because it was too quiet with so few nighttime wildlife noises.
Of course you could always have a go with ear plugs or play white noise to muffle it. Good luck.

I got used to it.
As a matter of fact the day that he died it was so quiet I could not recall the house being so quiet. That night I could not get to sleep so I turned the bed back on, laid on the bed and fell asleep.
If it is not bothering her I would not be worried about HER sleep.
If the bed is in a different room can you close doors to deaden the sound?
Have you tried putting a towel or blanket over the motor to muffle the sound. Or is it the air that is noisy to you?
If you got the bed through Hospice talk to them about it. There might actually be a problem the motor and or the mattress can be swapped out. Or another type ordered. If you got this yourself contact the company and see if they can take a look to make sure noting is wrong. But if they all say this is "normal" it will be something you will get used to. And you will miss it when it is gone.

If your mom isn't sleepier during the day, it would appear that she is doing ok with the noise. If she is restless at night, then it might be a problem. You can try playing soft music, using a white noise machine, using an overhead fan, or putting on headphones to try to cancel the noise.

The mattress is in fact one of those alternating pressure mattresses to prevent bed sores.... My mom developed a little one the size of my pinky nail so Hospice said they can get me this type of mattress. THey said they are all like this but that it does not necessarily mean that the noise is disrupting my moms sleep pattern. THat i can look at her eyes when i hear the noise and see if she is waking up. I will do that....Also i will try and track her cognition during the day.
If these types of mattresses are all the same and all noisy, then i am stuck and have to hope it is not disrupting her.

I am wondering if there is actually something wrong with this bed. It is difficult to imagine a machine so disruptive. Some of the portable negative pressure machines they use for air exchange in some hospital setting are difficult to hear over, for certain, but this just wouldn't be acceptable in a bed I would think. Call the place that delivered this to you.

I have an Aerobed, that I use when I have company spend the night. It automatically fills itself up when any air is lost while sleeping on it. It's very quiet when it refills itself, and I've never had any family members complain that it woke them up, nor have I ever heard it , and I am a very light sleeper. It's one of the nicer Aerobeds, that I ordered several years ago from QVC.
