High Flow Therapy

High Flow Therapy (HFT) provides support for patients of all ages experiencing shortness of breath or trouble with breathing. The difficulty in breathing may be caused by a variety of reasons. For newborns it may be due to immature and under-developed lungs. In children and adults it may be the result of an infection (e.g. pneumonia, RSV), a chronic disease (e.g. COPD or CHF), or breathing difficulty after a surgery procedure. High Flow Therapy is not designed for patients with a blocked windpipe or who are unable to breathe on their own.

Patients in respiratory distress must often work harder to breathe. High Flow Therapy reduces the work of breathing, and use a comfortable nasal cannula rather than a mask to deliver respiratory support.

Vapotherm HFT washes out exhaled carbon dioxide (CO2) from the nasal cavity and upper airway, and replaces it with fresh gas between breaths. In this way, the air that is breathed in includes more fresh oxygen, and makes each breath more effective at getting oxygen to the body.

One of the most important factors in assuring the effectiveness of HFT is to use a nasal cannula, which blocks less than half of the nostrils. This assures that air circulates freely inside the nose to efficiently flush all of the used gas, and that there is minimal pressure build up as a result of the flow. Vapotherm provides a variety of cannula sizes, including a single prong cannula for the smallest babies.

The Precision Flow box is usually mounted on a pole next to the patient bedside. The display shows the healthcare provider the current temperature, oxygen concentration and flow rate settings, and allows each of these parameters to be adjusted as needed.

The system also incorporates the patient's individual breathing circuit, where the breathing air is heated and humidified and delivered to the patient through a nasal cannula. The air must be heated and humidified in order to make the high flow rates safe and comfortable for the patient. The humidification also protects and soothes the tissue inside of the nose and may help loosen mucus and phlegm that builds up in the lungs.

Unique Vapotherm Precision Flow Features

The tube that carries the air to the patient is known as the delivery tube. In order to keep the air heated and humidified the tube has an inner channel for the air, surrounded by an insulating channel where warm water is continuously circulated. This water jacket tubing will feel warm to the touch, but is safe next to the skin because it only heats up to body temperature.

Vapor Transfer Cartridge
Vapotherm creates humidity in the breathing gas using a hollow fiber membrane filter. The filter transfers molecular particles of water to the gas, creating a very fine medical grade vapor. The filter size also prevents impurities from entering the air passageway.

The Vapotherm Precision Flow has audible and visual alarms built in to alert the healthcare provider to any problem with the operation of the system. For example, if the water bag is empty, or there is a kink in the cannula tubing, the healthcare provider can quickly assess the issue before anything can happen to the patient.

Take Comfort

Patients and families take comfort that Vapotherm High Flow Therapy (HFT) provides highly effective respiratory support without placement of a breathing tube or a mask covering the face. Adult patients can eat, speak and sleep comfortably, while babies can sleep and be cuddled.

Vapotherm therapy is a safe, non-intrusive therapy for yourself or family member.
