How many people go on ECMO?

I'm curious to know, could you provide an estimate of the number of individuals who undergo Extracorporeal Membrane Oxygenation (ECMO) therapy? Given the specialized nature of this life-saving procedure, I'm wondering if there's a rough figure that can be shared about its usage globally or perhaps within specific regions or healthcare systems. Is ECMO commonly utilized in certain medical conditions, and if so, how does that impact the patient numbers receiving this advanced form of support?
