FCV: Full respiratory control
Ventinova’s patented patient ventilation technique FCV® is unique in creating a stable gas flow into or out of the patient’s lungs to generate an inspiration or expiration, respectively. FCV® is a dynamic ventilation mode, without pauses, aiming for linear changes in both volume and pressure. There are no abrupt intrathoracic pressure drops because of the controlled expiration. FCV® is a more efficient ventilation as compared to conventional modes, allows ventilation through even small lumens (~2 – 10 mm ID) and results in less energy dissipation in the lungs.
FCV® uses relatively low flow rates that range typically between 8 and 16 L/min to adequately ventilate a patient. At these lower flows, gas is better able to reach the lung units that have higher resistance and the dependent lung parts, that have a better perfusion. By controlling the expiration flow, FCV® maintains airway pressure and keeps the gas longer in the alveoli. Thus, FCV® can avoid or delay airway and alveolar collapse, and thereby avoid atelectasis while improving gas exchange. Together, FCV® results in a higher efficient ventilation as compared to conventional ventilation techniques.
FCV® enables ventilation through ultrathin cuffed endotracheal tube Tritube® (O.D. 4.4 mm) . It provides numerous new possibilities for surgical treatment, especially during ENT or oral surgery: easy intubation of even difficult airways, increased surgical exposure with clear sight and non-vibrating vocal cords, and minimized contamination risk due to the cuffed airway.
FCV® results in smooth tidal movements of the diaphragm and thoracic wall. This is in contrast to conventional ventilation techniques where, especially during the passive expiratory phase, large instant intratracheal pressure drops are observed due to the collapsing thoracic wall. FCV® results in reduced application of mechanical power and less energy dissipation in the lungs.
