1. What are the primary goals of Airway Pressure Release Ventilation (APRV)? Airway Pressure Release Ventilation (APRV) is an unconventional pressure controlled mode of ventilation that use inverse ratio strategy. Moreover, APRV based on the principle of open-lung approach, and it is a lung protective strategy mode. Therefore, one of the primary goals of APRV is to decrease the incident of Ventilator-induced lung injuries (VILI). Another purpose of APRV is that APRV aims to recruit the lung as well as to improve oxygenation. To illustrate, APRV creates continuous sequences of positive airway pressure that would significantly increase the mean airway pressure (Paw) which would lead to Lung recruitment and improve oxygenation. Furthermore, APRV helps to decrease the inflation/deflation process which contributes in avoiding alveolar derecruitment. In a similar way, APRV applies pressure to sustain FRC for alveolar recruitment. Finally, APRV helps patient to eliminate CO2 efficiently. On APRV, CO2 is washed during the release phase, and during spontaneous breathing as patients on APRV are allowed to breathe spontaneously at any time at the respiratory cycle on APRV. In Summary, The primary goals of Airway Pressure Release Ventilation are to minimize Ventilator-induced lung injuries cases, help to recruit lungs, improve oxygenation, avoid alveolar derecruitment, and eliminate CO2 efficiently. 2.
