This problem often occurs with pressure support ventilation modes

Detailed explanation-1: -RISK FACTORS Sepsis, acidosis, anxiety, and fever are some of the factors that increase ventilatory demand and hinder the balance between the flow and volume demanded by the patient and those delivered by the ventilator, contributing to the occurrence of asynchrony.
Detailed explanation-2: -Patient-ventilator asynchrony, as mentioned above, is a lack of coordination between the patient and the ventilator due to a mismatch between neural and ventilator timing throughout the respiratory cycle or the magnitude of support provided and the support demanded. Several factors may cause asynchronies (Fig. 1).
Detailed explanation-3: -Studies indicate that NIV side-effects such as claustrophobia, stomach distension, nose sores, throat dryness and nasal problems can be very frightening and unbearable for most NIV patients, and this was related to suffering [24–27, 33].
Detailed explanation-4: -Non-invasive ventilation (NIV) is the delivery of oxygen (ventilation support) via a face mask and therefore eliminating the need of an endotracheal airway. NIV achieves comparative physiological benefits to conventional mechanical ventilation by reducing the work of breathing and improving gas exchange.
