The anaesthesia delivery system has the capability to operate at a very low Fresh Gas Flow. With its high end features and advanced ventilation capabilities, it can easily meet the challenging conditions in the room. Ventilating an obese or a patient in prone position is no longer a problem. The Hypoxic Guard and OFPD have been provided as standard safety protocol. While the hypoxic guard ensures FGF to contain at least 25% oxygen, the protection against oxygen failure (OFPD) activates a device to cut off the flow of NZO and wam, with a visual flash and an audio alarm. While the FGF Decoupling and the Circuit Compliance Compensation try to make for the net tidal volume, the system of breath to breath correction ensures the delivery unaffected with the change in lung characteristics. The Ascending Bellows in the ventilator provides visua! feedback for patient's response, leakages or low FGF. At times, the Pressure Control Mode is preferred to Volurne Control to avoid the likelihood of High Peak Pressure. The PRVC Mode, in such cases, delivers the target volume keeping the pressure to the minimum. The operator is relieved and is no longer required to adjust the pressure manually.
