Vocal supporters from a relatively small number of centers experienced with routine APRV
use are convinced that most of us are missing out on a great and underappreciated management tool.
Two techniques introduced before these investigative themes really heated up--high frequency ventilation and air-way pressure release (APRV
)--have now grown up and come of age.
is an intermittent ventilatory support mode that creates the potential for a patient's spontaneous breathing at any point during the ventilator cycle.
With new ventilation modes, such as APRV
and BiPAP, MV can be applied without restricting spontaneous respiration.
Although the patient produced copious quantities of bloody secretions after intubation, the secretions were reduced when APRV
was set to the highest airway pressure (35 cm[H.sub.2]O).

Lower mean airway pressure associated with CPAP and less ventilator dyssynchrony with CPAP and APRV
may also decrease pneumothorax.
Six patients received APRV
after CMV and then were switched to HFOV.
New concepts (eg, APRV
, recruitment, derecruitment) will be analyzed and related to the physical therapist's management of the patient.
SV is defined here as invasive mechanical ventilation with unimpeded spontaneous breathing effort+pressure support (PS) or airway pressure release ventilation (APRV
)+SV (5); SV is opposed to volume-assist control mode (14).
El modo ventilatorio de inicio fue el CMV en 80.8% de los pacientes (n = 114), seguido del PCV en 14.2% (n = 20) y el APRV
en 3.5% (n = 5).
Bi-level and Airway Pressure Release Ventilation (APRV
) are programs that incorporate variability into the ventilator.
