Description
Description
Nasal high flow (NHF) is a mode of noninvasive respiratory support that delivers high flows of blended air and oxygen through a nasal interface.
There are several mechanisms of action and benefits associated with NHF therapy for neonates, infants, and children.
Reduces anatomical dead space
Wash-out of the anatomical dead space in the nasopharyngeal cavity is a principal mechanism of action of NHF.
Dynamic positive airway pressure
The delivery of dynamic positive airway pressure associated with NHF has been shown to reduce inspiratory effort and work of breathing compared to standard oxygen therapy.
Improves patient comfort
NHF is gentle on the nose, which improves patient comfort, compliance, and tolerance to therapy.

Do I need a prescription to buy a CPAP or BiPAP machine?
Do I need a prescription to buy a CPAP or BiPAP machine?
Yes. In the U.S., the FDA requires a prescription for CPAP and BiPAP machines. Masks, tubing, and most accessories can be purchased without one. If you’re unsure what you need, we can help guide you through it.
How often should I replace my mask, tubing, and filters?

How loud are CPAP and oxygen concentrator machines?
Most modern CPAPs run at around 25–30 decibels — about as quiet as a soft whisper. Oxygen concentrators are slightly louder, but still comfortable for home use, especially when placed a few feet away from the bed.
