Lena mask L
SKU: 253
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.
Mask cushion with double lip:
The mask cushion is characterized by its double lip. The therapy pressure creates an air cushion that provides a perfect seal without causing any pressure points. The shape mirrors the anatomy and is based on two factors: Our patient face database that has been growing for many years and the market feedback that is constantly collected and evaluated.
Connections mask body - mask cushion:
Another important factor is the connection between the mask cushion and mask body. On the one hand, the connection must be stable during the therapy – both at constantly high pressures and with high pressure differences during inspiration and expiration with BiLevel therapy. On the other hand, the connection must be easy to disassemble to allow for simple and effective cleaning. This seems paradoxical, but LENA solves it well.
Stable headgear:
The headgear completes the essential triad. The material of the headgear is so sturdy that the mask remains leak-free and stable even under high pressure differences. An individually adjustable forehead support with forehead cushion gives LENA extra support.

Reminder:
A BiPAP (also known as BPAP) system, or Bilevel Positive Airway Pressure, is a type of non-invasive ventilation device used to assist breathing.
BiPAP is commonly used to treat conditions like sleep apnea, COPD, obesity hypoventilation syndrome, and other respiratory issues.
The Prisma SMART is an automatic CPAP/APAP device designed for the effective treatment of sleep apnea. This intelligent device offers personalized therapy based on your breathing patterns, ensuring comfortable and uninterrupted sleep.
Key Benefits:
Intelligent Pressure Adjustment: The device features Standard and Dynamic modes that automatically adjust pressure to deliver personalized and optimal treatment.
softPAP Technology: This function reduces exhalation resistance, ensuring natural and comfortable breathing during sleep.
softSTART Function: Pressure gradually increases at the beginning of sleep, allowing users to adapt smoothly to therapy.
Prisma RECOVER: This feature analyzes and monitors deep sleep phases, ensuring the full effectiveness of treatment.
Pressure up to 20 cm H₂O: The device can deliver up to 20 cm H₂O of pressure, making it suitable for all cases of sleep apnea treatment.
Comfort Features:
Heated Humidifier (prismaAQUA System): Prevents airway dryness, making therapy more comfortable.
Ultra-Quiet Operation (<26 dB): The device operates almost silently, ensuring it does not disturb your sleep or that of others.
User-Friendly Interface: A simple LED screen and easy controls ensure hassle-free operation.
Remote Monitoring & Control:

Connective APAP therapy: Flexible. Secure. Reliable.
With prisma SMART in the plus, we offer modern and reliable APAP therapy trough integrated connectivity, precise event detection and a high level of patient comfort. The plus represents integrated Bluetooth® for data transmission to the prisma APP, enabling modern patient self-management.
- The most important features at a glance.
Prisma SMART is available in the plus version, which offering two dynamic options for pressure adjustment in APAP mode. The device is whisper-quiet, providing greater comfort, well-being and restful sleep for our patients and their partners. The well-known advantages of Löwenstein Medical's proven prisma devices are combined with modern connectivity. This allows you to always keep an eye on your therapy.
- Smart networking.
The prisma SMART in plus variant enables intelligent networking between sleep diagnostics and sleep therapy. It is directly connected to our Samoa polygraph system - wirelessly via Bluetooth®.
- A variety of comfort features.
Patient comfort is enhanced trough various functions and modes. For example, patients benefit from the softPAP pressure relief feature. Here, the pressure is lowered at the start of expiration and raised back to the therapy pressure at the start of inspiration, maximizing exhalation comfort and effectively avoiding events. In addition, the softSTART mode, characterized by a slow pressure increase over a preset time up to the therapy pressure, supports comfortable falling asleep. This facilitates acclimatization to therapy pressure during the sleep onset phase.
- Reliable differentiation.
For a seamless therapy, the device reliably differentiates between obstructive and central apneas. This is made possible by the integrated Forced Oscillation Technique (FOT). FOT detects periodic breathing, RERA, snoring, hypopneas, apneas and flow limitations.
- Product features:
- prismaAQUA
prismaAQUA is the powerful respiratory air humidifier for the world of sleep apnea therapy devices. It humidifies and warms the breathing air to prevent the patient's mucous membranes from drying out.
- Pressure reaction fits patient’s needs
Patients react with varying sensitivity to pressure adjustments. For effective therapy and breathing comfort, two options for pressure adjustments are available in APAP mode. In addition, a pressure increases at closed central events is avoided.
- Modern connectivity
Compatible and future-proof. Various interfaces such as SD, PSG, LAN and external modem offer various options for data transfer. Our software solutions (e.g. prismaTS, prisma APP and prisma CLOUD) are available for simple, flexible and secure therapy support.
