Leoni Neonatal Ventilation

Leoni Neonatal Ventilation

Leoni plus is suitable for long-term ventilation of very small premature infants, neonates and children weighing up to 30 kg. In addition to the basic ventilation modes CPAP, IPPV/IMV, S-IPPV and SIMV, the device also features two PSV ventilation modes.

In assisted ventilation modes there is a volume-controlled tidal volume guarantee available.
The precision hot-wire flow sensor at the patient end allows automatic readjustment of trigger sensitivity relative to the patient‘s tidal volume (VT trigger adaptation).

The extremely powerful, integrated high-frequency module Leoni HFO is of the diaphragm type.

All essential settings, readings, alarm limits and graphic information, such as waves and loops, are

available at a glance.

In order to expand the range of possible uses Leoni plus features an integrated battery. This allows off-mains operation for up to 60 minutes in conventional ventilation modes and for up to 30 minutes in HFOV.

The manual regulation of inspiratory oxygen (FiO2 ) used to supply oxygen to premature infants, is often complicated and time-consuming. In collaboration (1) between Tübingen University Hospital and the Medical & Technical University of Vienna, a special algorithm was developed to automate the oxygen control provided to premature infants (CLAC: Closed-Loop Automatic Oxygen Control). Löwenstein Medical were able to validate these experiment results in a multicenter study (1) using the Leoni plus in daily hospital operations. In order to make the CLAC controller operation as easy and intuitive as possible for the user, the algorithm control and pulse oximetry measurement were integrated into the Leoni plus (2). The entire operation, including the measured data visualization and the alarm settings, is made over the respirator user interface. At a glance, the user can determine the current graphically displayed status of the patient. CLAC takes the routine adjustment of the inspiratory oxygen (FiO2) in inspiratory gas off the clinician‘s shoulders by constantly monitoring the demand and condition of the patient in adapting the equipment settings accordingly. Thus, the user is relieved of the routine tasks. The user has the possibility to switch off the automatic control at any time in order to regulate the oxygen content manually. „CLAC may improve oxygen administration to preterm infants receiving mechanical ventilation or nasal continuous positive airway pressure while reducing workload related to RMC. (Pediatrics 2014;133:e379–e385)“ (1).

Patient transport with HFO – no problem with the new Leoni plus Transport.

Leoni plus Transport expands your possibilities especially for transport of patients. The device has an integrated high-performance battery that enables stand-alone use for up to 200 minutes in conventional ventilation modes and up to 60 minutes in HFOV.

The display adapts to the requirements of the user by means of the free selection of the number of curves and loops and displayed measurement values. Leoni plus Transport has comprehensive ventilation modes: CPAP, IPPV/IMV, S-IPPV/ SIMV and two PSV modes. Leoni plus Transport features certification for ground transport.

  • Simple and intuitive operation
  • Uncompromising ventilation performance
  • Certified for ground transport
  • 12’’ TFT colour screen, detachable
