Descriptions:
The Philips BiPAP S/T device is intended to provide non-invasive ventilatory support to treat adult patients weighing over 30 kg (66 lbs) and pediatric patients 7 years or older and weighing over 18 kg (40 lbs)
with Obstructive Sleep Apnea (OSA) and Respiratory Insufficiency. This device may be used in the hospital or home.

Technology Hightlight:
The BiPAP S/T device is intended to augment patient breathing by supplying pressurized air through a patient circuit. It senses the patient’s breathing effort by monitoring airflow in the patient circuit and adjusts its output to assist in inhalation and exhalation. This therapy is known as Bi-level ventilation. Bi-level ventilation provides a higher pressure, known as IPAP (Inspiratory Positive Airway Pressure), when you inhale, and a lower pressure, known as EPAP (Expiratory Positive Airway Pressure), when you exhale. The higher pressure makes it easier for you to inhale, and the lower pressure makes it easier for you to exhale. The device can also provide a single pressure level, known as CPAP (Continuous Positive Airway Pressure).
When prescribed, the device can also provide features to help make your therapy more comfortable. The ramp function allows you to lower the pressure when trying to fall asleep. The air pressure will gradually increase until the prescription pressure is reached. Additionally, the Flex comfort feature provides increased pressure relief during the expiratory phase of breathing.
Several accessories are also available for use with the device. Contact your home care provider to purchase any accessories not included with your system .
