Most of the time, many people don’t even notice their breathing. It’s a natural, often effortless process. Patients with respiratory insufficiencies or sleep-related breathing disorders need help with this. LENA has been developed specifically for ventilation. The focus is primarily on a comfortable mask fit, especially when high pressures are applied or when the pressure difference between inspiration and expiration is considerable. LENA is available in vented and non-vented versions. We also offer the NV endoscopy adapter as an accessory.
