What is usually the end result of patient ventilator asynchrony?

When a patient experiences ventilator asynchrony, it typically leads to increased work of breathing. This condition occurs when the timing of the ventilator's breaths does not align effectively with the patient's own respiratory efforts. As a result, the patient may have to exert more effort to breathe, which can lead to muscle fatigue and discomfort.

In this situation, rather than achieving a state of ease and comfort, the patient might struggle to synchronize their natural breathing pattern with the mechanical ventilator. This mismatch can cause the patient to have to work harder to initiate breaths or to overcome the pressure support provided by the ventilator. This increased effort can result in respiratory fatigue, which is counterproductive to achieving effective ventilation and can negatively impact overall oxygenation.

Therefore, the most likely outcome of patient ventilator asynchrony is increased work of breathing, as the patient finds it more challenging to rescue their own ventilation alongside the mechanical support they are receiving.
