Vapotherm, Inc. is the market leader in high-flow, thermally-controlled, humidification systems or respiratory therapy. Currently, these medical devices are indicated for use in adding warm moisture to breathing gases to infant, pediatric and adult patients in the hospital, sub-acute institutions and home settings. Vapotherm devices are cleared for delivery of breathing gases by nasal cannula at flow rates of up to 8 lpm in infants and 40 lpm in adults, providing what is known as high flow therapy (HFT).
What is High Flow Therapy (HFT)?
HFT is defined as flow rates that exceed patient inspiratory flow rates at various minute volumes. Historically, high flow therapy has been used with face masks, where the high flows flush the mask volume to facilitate high inspiratory oxygen fractions. While effective in supporting oxygenation, mask therapy can be limited by factors including ability to eat/drink and communicate, as well as feelings of claustrophobia, leading to poor patient compliance. The standard nasal cannula has been the standby for better compliance and patient comfort. Cannulae provide supplemental oxygen, are comfortable for long periods and allow patients to eat and talk without interruption of the therapy. However, higher flows (over 2 lpm in neonates or 6 lpm in adults) needed to meet inspiratory requirements without allowing entrainment of room air are not possible with conventional nasal cannula therapy. This limitation to conventional cannula therapy is a result of the discomfort and irritation caused by delivering cold, dry gas to the nasal passages. Vapotherm's technology has transformed conventional cannula therapy through optimal conditioning of breathing gas.
