FCV: Full respiratory control
Ventinova’s new ventilation technique FCV®is unique in controlling the inspiration as well as the expiration phase during artificial ventilation of a patient. This is established by generating a continuous flow into the patient’s lungs followed by a continuous (negative) flow, sucking gasses out of the patient’s lungs. The continuous flow either into the lungs or out of the lungs, without ventilation pauses, results in linear increases and decreases in intratracheal pressures.
FCV® ventilation is based on creating linear increases and decreases in intratracheal pressures. As a result, the mean airway pressure will be higher as compared to conventional large bore Volume Controlled Ventilation or Pressure Controlled Ventilation. Therewith bronchiole and alveoli will be kept more open during ventilation facilitating oxygen uptake in the blood. Moreover, the continuous gas flow enhances gas mixture in the lungs also improving gas exchange. All together FCV®results in a higher efficient ventilation as compared to conventional ventilation techniques.
FCV® is based on a controlled, stable flow with pressures at the tip of the endotracheal tube just high enough to generate a linear increase in intratracheal pressure during inspiration and a pressure just low enough to generate a linear decrease in intratracheal pressure during expiration. This is in contrast to Pressure Controlled Ventilation and Volume Controlled Ventilation where, especially during the passive expiratory phase, large instant intratracheal pressure drops are observed due to the collapsing thoracic wall.
FCV® enables ventilation through small bore, high resistant tubes, -with an inner diameter of <3 mm – in sealed or obstructed airways. Therewith it has saved lives in CICO situations and it has provided numerous new possibilities for surgical treatment, especially during ENT or oral surgery: the surgeon has a hygienic and clear sight and a spacious surgical exposure.
