The tricky part isn't the mechanics of it, it's regulating the composition of air you're delivering and also making sure that air remains as clean as possible. Hypothetically, you could just plug a set of bellows into a breathing tube, shove that down your throat, and use that as a ventilator, but you'd risk mold growth and dust accumulation in the air you're pumping in there, and you'd be limited to the 20-22% oxygen found in regular air. Shove a filter in the intake and run the breathing tube through a strong UV light, and maybe you'd be getting somewhere.
An iron lung is a totally different kind of machine than a ventilator. The body is encased in a large chamber with the head sticking out. The pressure is lowered in the chamber, which causes the lungs to expand. By repeatedly increasing then decreasing the pressure, the patient is made to breathe.
