Puritan Bennett 560 Repair

If you are having issues with your ventilator, check out Puritan Bennett 560 Troubleshooting.

The Puritan Bennett 560 (PB560) was released to medical practitioners in 2010. It is currently sold in 35 countries around the world, for an average price of $10,000 per unit. It is lightweight and compact weighing only 9.9 lbs (4.5 kg). It also features a long battery life of 11 hours of ventilation operation (depending on settings) and it includes a real-time battery life indicator. It can also run on AC or DC power. The ventilator uses a USB memory device to transfer patient data from a home ventilator to the clinician’s computer allowing for great data portability. Included are alarm settings that reduce the risk of the device operating under inappropriate settings. Oxygen enrichment is available using a low pressure oxygen source.

Medtronic has open-sourced all documentation for the PB560 ventilator design in response to the COVID-19 pandemic, “to allow innovators, inventors, start-ups, and academic institutions to leverage their own expertise and resources to evaluate options for rapid ventilator manufacturing.” As a result of the COVID-19 pandemic, Medtronic announced that it expects to increase production to 25,000 devices available over the next six months as of April. The company has also announced that it will be sharing the design specifications for the Puritan Bennett 560 to accelerate the increase in global ventilator production.
