Brief Summary:
Flow-Controlled Ventilation is designed to ventilate the patient with constant flows during both inspiration and expiration During inspiration the pressure rises linearly from a set positive end-expiratory pressure PEEP to a set positive inspiratory pressure PIP and then falls linearly from PIP to end-expiratory pressure EEP during expiration There are no flow interruptions during the Flow-Controlled Ventilation cycle and the rate of change of pressure and volume in the lungs is equal allowing for higher tidal volumes at lower pressures The user sets the inspiratory flow rate and the ratio of inspiratory to expiratory time providing full control over the ventilation cycle However this results in two unusual features During inspiration the ventilator creates positive pressure to direct gas into the patients lungs through the endotracheal tube ETT When the intratracheal pressure airway pressure reaches the set PIP value the ventilator switches from inspiration to expiration By reversing the flow it utilizes the Bernoulli effect to create negative pressure facilitating expiration Despite the presence of negative pressure on the ventilator side the pressure in the patients airway remains positive at all times
Volume-controlled ventilation is a mode that is volume-controlled time-cycled time-triggered and pressure-limited In volume-controlled ventilation high pressures are sometimes necessary to reach the target tidal volume This can lead to barotrauma atelectrauma and volutrauma in the lungs Therefore to avoid high pressures low tidal volume ventilation is preferred
For Microscopic Laryngeal Surgeries patients are intubated with a small sized endotracheal tube which results with higher pressures We think that flow controlled ventilation will improve the ventilation during the surgery with lower pressures
