As a PS In the past most inverters I have looked at have said that they are not for use with medical life support equipment.
300 watts/VA at mains voltage is not much but at 12 volts that is going to draw 25 amps, that needs decent wires and a good battery.
Graham mentioned the Prosime 1000i that can deliver 240v at 10A. That would draw 200A assuming 100% efficiency.That can really do damage to a battery if used for any significant time.
One of the problems with inverters is not the output but the input.
