Medical ventilator for G8

Caetlyn

I know there're a few sci-fi ventilators (masks) around but does anyone know where I can find a wearable present-day one (but not a mask)? Something that looks similar to this - https://healthscopemag.com/wp-content/uploads/2013/12/ventilator.jpg

I'm looking for one especially for a G8 character. Thanks!
