In HFT mode the device provides a constant flow of five to 60 liters per minute. An oxygen feed also can be added. The flow of air is heated and humidified (for example, with prisma VENT AQUA) and delivered to the patient via a nasal cannula. The patient interface comes in different sizes for non-invasive use. A different interface is available for invasive application.
The prisma VENT50-C also may be used with a single tube with patient valve and with other tube systems with nasal cannula for High-Flow Therapy.
