Airway pressure release ventilation APRV is inverse ratio, pressure controlled, intermittent mandatory ventilation with unrestricted spontaneous breathing. It is based on the principle of open lung approach. It has many purported advantages over conventional ventilation, including alveolar recruitment, improved oxygenation, preservation of spontaneous breathing, improved hemodynamics, and potential lung-protective effects.

Intelligent ventilation mode for passive and spontaneously breathing adult and pediatric patients. Next-generation intelligent ventilation mode that automatically controls ventilation and oxygenation based on targets set by the clinician.

Airway pressure release ventilation during acute lung injury: a prospective multicenter trial

Airway pressure release ventilation APRV is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. Depending on the ventilator manufacturer, it may be referred to as BiVent. This is just as appropriate to use, since the only difference is that the term APRV is copyrighted. Airway pressure release ventilation was described initially by Stock and Downs in [2] [3] as a continuous positive airway pressure CPAP with an intermittent release phase. APRV begins at a pressure higher than the baseline pressure and follows with a deflation to accomplish tidal ventilation. Based on clinical and experimental data, airway pressure release ventilation is indicated in patients with acute lung injury , [6] [7] acute respiratory distress syndrome [8] [9] and atelectasis [1] after major surgery.

Airway Pressure Release ventilation APRV is a relatively new mode ofventilation, that only becamecommercially available in the UnitedStates in the mids. Airway pressurerelease ventilation produces tidalventilation using a method that differsfrom any other mode. It uses a Release ofairway Pressure from an elevatedbaseline to simulate expiration. Theelevated baseline facilitates oxygenation,and the timed releases aid in carbondioxide of APRV include lowerairway pressures, lower minuteventilation, minimal adverse effects oncardio-circulatory function, ability tospontaneously breathe throughout theentire ventilatory cycle, decreasedsedation use, and near elimination ofneuromuscular blockade. Airway pressurerelease ventilation is consistent with lungprotection strategies that strive to limitlung injury associated with mechanicalventilation. Future research will probablysupport the use of APRV as the primarymode of choice for patients with acutelung injury.

Airway pressure release ventilation: theory and practice.

To evaluate the feasibility of airway pressure release ventilation APRV in providing ventilatory support to patients with acute lung injury of diverse etiology and mild-to-moderate severity. Prospective, multicenter, nonrandomized crossover trial. ICUs in six major referral hospitals. Fifty adult patients with respiratory failure requiring mechanical ventilation and positive end-expiratory airway pressure. During APRV, the CPAP level and airway pressure release level were adjusted to prevent hypoxemia, while the degree of ventilatory support was adjusted by altering the frequency of pressure release. Circulatory and ventilatory pressures, arterial blood gases and pH, heart rate, and respiratory rate were measured. Alveolar ventilation was augmented adequately in 47 of 50 patients by APRV.

 Если все пойдет хорошо, то результат будет примерно через полчаса. - Тогда за дело, - сказал Стратмор, положил ей на плечо руку и повел в темноте в направлении Третьего узла. Над их головами куполом раскинулось усыпанное звездами небо.

То же самое будет и со мной, - подумала. Сьюзан вспомнила о единственном остающемся выходе - личном лифте Стратмора. Но она понимала, что надежды нет: электроника вряд ли уцелела после катастрофы. Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания. Я видел схему.

Из нее делают струны для ракеток. - Как мило, - вздохнула. - Итак, твой диагноз? - потребовал. Сьюзан на минуту задумалась. - Склонность к ребячеству, фанат сквоша с подавляемой сексуальностью. Беккер пожал плечами: - Не исключено, что ты попала в точку. Так продолжалось несколько недель.

 Нам нужна ваша помощь. Она с трудом сдерживала слезы. - Стратмор… он… - Мы знаем, - не дал ей договорить Бринкерхофф.  - Он обошел систему Сквозь строй. - Да… и… - слова застревали у нее в горле. Он убил Дэвида. Бринкерхофф положил руку ей на плечо.
