The A4/6 is a newly developed ventilator, which may be used in the operating theatre or in the intensive care unit. The machine is electronically driven (microprocessor) and is characterised by a highly sensitive triggering mechanism. It is designed for the ventilation of the newborn (including premature infants) and children up to approximately 5 years. The significant and important features of its control design including its triggering mechanism will be described.
