What is the advantage of using Volume Cycled Ventilation?

1) The ventilator pushes air into the lungs until a preset airway pressure is reached.
2) The ventilator pushes air into the lungs until a preset volume is reached.
3) A constant tidal volume is delivered regardless of the pressure needed to deliver the tidal volume.
4) It limits excessive pressure being exerted on the lungs.
5) It allows the health care team to determine if intubation is really necessary.

The primary advantage of Volume Cycled Ventilation is that it delivers a constant tidal volume, preventing lung overdistension by controlling the volume of air pushed into the lungs, rather than the pressure applied.The correct answer is option 3.

Explanation:

The advantage of using Volume Cycled Ventilation is that a constant tidal volume is delivered regardless of the pressure needed to deliver the tidal volume. This method ensures that each breath delivered to a patient has a preset volume, which can be critical in ensuring adequate ventilation without overdistending the lungs. In volume cycled ventilation, the ventilator pushes air into the lungs until a preset tidal volume is reached, rather than based on reaching a certain airway pressure.

Tidal volume (TV) is the amount of air inspired and expired during normal breathing, and it typically measures around 500 milliliters for a healthy adult. The concept of tidal volume is essential in respiratory mechanics and reflects how volume cycled ventilation works. This mode of ventilation protects the lungs from the damage that might occur if excessive pressure were to be used in ventilating a patient.
