For customers that currently receive order acknowledgements: All ventilator and range of accessories orders are currently being monitored to allow us to allocate them across the European and the Middle East regions. To maintain this, all ventilators are shown as backorders on your order acknowledgment. So as to have a fair allocation system, delivery volumes are being allocated very late in the process, to be shipped for the next coming days. To ensure an efficient process, we are not able to send any advance delivery notification. However, if you have received a partial delivery and would like to confirm the number of outstanding items in an order, please contact our customer service team. All outstanding orders or part-orders are kept in our system and will be reviewed during the next biweekly allocation process. For non-ventilator products, backorders are shown on the order acknowledgment as normal. ResMed is fulfilling all backorders as soon as stock becomes available and our warehouses are working very hard to fulfil orders daily. We are aware that for some countries there are transport delays due to congestions at borders; rest assured, we are working tirelessly to keep goods flowing. All orders are kept in our system and dealt with as quickly as possible.   For customers that currently do not receive order acknowledgements: All ventilator and range of accessories orders are currently being monitored to allow us to allocate them across the European and the Middle East regions.
