We are trading & supplying DreamStation BiPAP Pro Machine from New Delhi, Delhi, India. Philips Respironic's DreamStation BiPAP Pro Machine combines pressure relief technology with OPTIONAL humidification to increase comfort on a dual pressure machine. Bi-Flex is built into the device to soften the transition between the higher IPAP and the lower EPAP. Warm air from the humidifier and water chamber is provided to therapy air by integrating the OPTIONAL DreamStation Heated Humidifier with the machine. Therapy results can be viewed on a handheld device (not included) by connecting the machine's Bluetooth to the PR DreamMapper app.Manufactured by Philips Respironics.
