To me, the dialogue with engineers, technicians, and manufacturers has always been very important – the exchange of knowledge between users and the developers is vital. Our requests regarding the ventilators were listened to and implemented wherever possible.

during HFO can be applied at any time. Recruitment manoeuvres under HFO recruit short-term alveolar capacities and keep them open through an adequately high PEEP. The system offers continuous real-time
measurement of the CO2 partial pressure in the breathing gas through end-tidal CO2 measurement. In addition, all ventilation modes can be performed with the same tube system – all without the need for time-consuming or risky system changes. Settings and alarms can be individually programmed and saved for the neonatal and paediatric patient groups.
NIV trigger LEONI 4 enables synchronised breathing support for spontaneous breathing efforts – the benefits of synchronised NIV have been widely proven in studies, successfully reducing reintubation rates, decreasing the frequency of desaturations, bradycardias and central apnoea episodes.
Ventilation performance Tidal volumes as low as 0.1 ml enable ventilation for even the smallest premature infants, while volume guarantee and volume limitation protect the sensitive lungs of premature and newborn babies.
Abdominal sensor There is also an added advantage of an abdominal sensor – in the first few months of life, diaphragmatic or abdominal breathing is very pronounced in our smallest patients. What could be more natural than monitoring children’s breathing activity at the diaphragm and using the signals gathered to trigger inhalation
As a user, I was impressed with the stability, safety, service, support, assistance in emergencies, long-term collaboration, and recognition of nursing in patient care.

efforts? The LEONI 4 neonatal ventilator synchronises the non-invasive ventilation modes s-nIPPV and s-nCPAP with the optional abdominal sensor and simultaneously functions as apnoea monitoring in both ventilation modes.
Closed-Loop Automatic Oxygen Control Löwenstein has also developed a unique algorithm for automated oxygen control in premature and newborn babies (CLAC: Closed- Loop Automatic Oxygen Control) and integrated it into LEONI 4. The entire operation, including the visualisation of measurement data and alarm settings, is managed through the ventilator’s user interface. The user can quickly assess the patient’s current status through the graphically displayed overview.
Quiet operation The improved system architecture of the LEONI 4 allows nearly silent operation, particularly at high
amplitudes and rates during high-frequency oscillatory ventilation (HFOV).
Conclusion Ultimately, LEONI 4 sets new standards in user-friendliness, while significantly increasing operating safety. Users, caregivers and the tiniest patients all benefit from a safe, calm and comfortable ventilation environment. The LEONI 4 has now been successfully tested and challenged by users under real-world clinical conditions – giving clinicians the confidence and peace of mind they need when ventilating the tiniest and most vulnerable patients.
