Narcotic and respiratory device VENAR LIBERA Screen XE, Chirana s. r. o .  (Slovakia), the modern modular anesthesiology device, for safe use of all types of anesthesia, including Low - Flow and Minimal - Flow anesthesia. Availability of the unique electronic rotameter, including under Xe (xenon), allows to control completely amount of the gases arriving to the patient and to carry out control of their expenditure the Narcotic block supplied with the high - precision electronic rotameter and two evaporators (for any modern inhalation anesthetics for choice), gives the chance most optimum to pick up the IVL parameters to newborns, children and adult patients. Additional equipment of the device - the ICARD monitor (control of hemodynamic indicators: EKG, SpO, CO, Temp, NIBP). The additional complete set of the device the module of gas analysis of AGAS allows the anesthesiologist to exercise control of composition of respiratory mix on a breath and an exhalation (CO2, N2O, a halothane, sevoran, isoflurane, desflyuran, enflurane and IAC).

The narcotic and respiratory device VENAR LIBERA Screen XE   has:

  • Modern anesthesiology device;
  • The electronic rotameter for work with xenon.

Technical parameters of the narcotic and respiratory device VENAR LIBERA Screen XE :



Respiratory volume (ml)

20 - 1500

Respiration rate

4 - 60/mines

Minute ventilation (l/min)

0,5 - 25

Ti: Te, %

 from 1: 4 to 4: 1

Inspiratory pause

 from 0 to 50%


electronic, protection of hypoxemic mix, electronic control of FiO2, composition of respiratory mix

Holder of evaporators

on 2 evaporators

Ventilation modes:

CMV – the ventilation managed on volume
PCV – the ventilation managed on pressure
SIMV - PS – synchronized replaceable ventilation with support by pressure of spontaneous breath at the level of PEEP pressure
PS – support by pressure at spontaneous breath of the patient
MAN – manual ventilation by means of Ambu's bag
SPONT – ventilation at independent breath of the patient
The SIMV - PS, PS and SPONT modes are necessary for optimization of processes of synchronization of breath of the patient and operation of the fan.


In devices of the Screen series the integrated ABC contour is used


In devices of the Screen series the three - level system of alarms, the sound and light notification with display and storing of the reason is implemented. Availability of the program allowing, at a task of weight of the patient, to carry out fast start of the device in work in the mode of ventilation CMV that is extremely important in case of emergency. The electronic rotameter provides the increased protection against hypoxemic mix, an additional insurance is electronic control of FiO2. At oxygen interruption in supply the device podsasyvat air from surrounding space. The minimum operating time of the built - in accumulator – 120 minutes.

Active system of removal of exhaust gases

System of automatic switching of supply of gas from the central distributing on cylinders and back

System of fastening of SelectaTec Interlock evaporators

Provides fast change of evaporators during an opertion, possesses debugged and reliable system of blocking of the evaporator which is not working at present. The Penlon evaporator -  "the gold standard" among evaporators of pore - forming anastetik.

Fan monitor built - in, color contrast TFT display 6,4"

Ventilation parameters in numerical and graphic display, indicators of mechanics of breath: Cdyn, Cst, Riaw, autoPEEP, temporary constant, intra alveolar pressure upon breaths and exhalation.

Electronic rotameter

Controls giving and an expense of O2, air, N2O, xenon;
Automatic calculation and correction of values of gases and a necessary proportion on the specified total flow;
More exact dosing of gases, monitoring of a flow is fresher than mix;
The increased level of protection against a hypoxia due to monitoring 
of FiO2;
Display of a consumption of gases during operation, totally and on each gas separately;
Indication of a flow is fresher than mix in a digital form and in the form of charts columns.

The minimum operating time from the accumulator not less than 90 minutes

System of supply of By - Pass oxygen
Built - in injection bronkhootsos
Additional "float - operated rotameter" O2
Built - in little table of the doctor
Galogenovy lamp
Rack for fastening of the monitor of the patient
Autonomous illumination of the main technical nodes at an emergency shutdown of the electric power

Use of xenon in medicine:

Xenon is applied as gaseous means to the general anesthesia.
Use at a mask monoanaesthesia and in the combined endotracheal anesthesia in combination with different sedative drugs, neuroleptics, muscle relaxants and local anesthetics.

Xenon route of administration:

Xenon to be entered into an organism in the inhalation way in a look xenon - oxygen mix with concentration of xenon no more than 70% . Respiratory gas mix forms in the narcotic device Chirana Venar Xe.

Advantages of xenon anesthesia:

  • Fast introduction to anesthesia with strongly expressed myorelaxation and analgetic by properties;
  •   Stable indicators of a hemodynamics and gas exchange;
  • Lack of toxic loading;
  • Does not participate in biochemical processes in an organism;
  • Protection of cells of a nervous system;
  • It can be entered in combination with any medicines;
  •   Awakening of patients fast and pleasant, without narcotic abstinence.

Properties of xenon:

Xenon thanks to the unique physical and chemical properties of noble gas finds more and more broad application in medicine. It opens the new horizons in medicobiological practice as combines a hypotoxicity with an opportunity to be dissolved in biological liquids and cellular membranes, to carry out impact on exchange and cellular processes by means of physical and biophysical mechanisms. Xenon has more powerful narcotic force in comparison with N2O. Its IAC = 50% . In the conditions of a monoanesthesia at concentration of 70 - 80% of He in 5–6 min. causes a surgical grade of anesthesia, provides adequate anesthesiology protection. Awakening comes in 2–3 minutes after interruption in supply of ksenono - oxygen mix to the patient with a complete recovery of consciousness and pleasant feelings.

Pharmacodynamics and pharmacokinetics, toxicity of xenon:

  • Let's poorly dissolve in fluid mediums of an organism, it eliminirutsya quickly mainly through lungs, is not exposed to biotransformation. Possesses ability to contact proteins of plasma, hemoglobin and a myoglobin.
  • Xe possesses high solubility in lipids, therefore is distributed in body tissues unevenly. Accumulation of substance is noted in fatty tissue and in well vaskulyarizovanny regions, more in adrenal glands, than in a brain.
  • Subchronic purpose of He (2,5 h/day within 7 days) does not cause toxic influence on life support systems: brain, lungs, liver, kidneys, adrenal glands.
  • He/O2 (70/30) leads to single pycnosis of kernels in bark and marrow of adrenal glands of rats However in case of mix inhalation protoxide nitrogen/oxygen (70/30) similar changes are more expressed.
  • Xe does not possess acute and chronic toxicity, teratogenecity and embriotoxity, is not allergen, does not break integrity of structures of a brain.
  • In narcotic concentration of He causes increase in a linear brain blood - groove, at the same time intracranial pressure does not increase. The metabolism of a brain does not change.
  • Does not influence indicators of cardiovascular and hemodynamic systems in narcotic concentration. Inhalation mix of 70% of xenon — 30% of oxygen the first 15 min. reperfusion after regional ischemia at rats reduces the myocardial infarction sizes in comparison with pure oxygen.
  • In the conditions of induction of anesthesia xenon in mix with oxygen of 75% for 25% possesses some promoting effect on cardiovascular (tachycardia) and respiratory systems (increase in minute ventilation).
