Effect of positive end-expiratory pressure and tidal volume on lung injury induced by alveolar instability

Abstract: Introduction One potential mechanism of ventilator-induced lung injury (VILI) is due to shear stresses associated with alveolar instability (recruitment/derecruitment). It has been postulated that the optimal combination of tidal volume (Vt) and positive end-expiratory pressure (PEEP) stabilizes alveoli, thus diminishing recruitment/derecruitment and reducing VILI. In this study we directly visualized the effect of Vt and PEEP on alveolar mechanics and correlated alveolar stability with lung injury.

“…15 PEEP is used to maintain alveolar patency and stability at end-expiration but during tidal ventilation is usually set at a level insufficient to overcome the threshold opening pressure of atelectic alveoli. [25][26][27] Increasing PEEP effectively allows the clinician to manipulate the functional residual capacity (FRC) and thereby minimise physiological deadspace, improving ventilation/perfusion mismatch and decreasing shunt fraction. 6,12,[28][29][30] Boriosi and colleagues chose this method of recruitment to assess the safety and efficacy of the open lung tool in paediatrics.…”

“…As a rule, regardless of the type of ventilation, all ventilation modes use a positive end-expiratory pressure (PEEP) of 4 cm H 2 O, and sometimes as much as 15 cm H 2 O [6].…”

“…Pavone ve arkadaş-ları 26 yüksek TV ile ventile edilen hayvanlarda alveoler duvarlarda kalınlaşma, inflamatuar hücrelerde artış ve alveoler ödem geliştirmiş ve düşük TV ile yüksek PEEP uygulayarak bu değişikliklerin hepsinin azaldığını göstermiş-lerdir. Benzer bir yöntemden yararlanan Halter ve arkadaşları 27 ise, ratlarda yüksek TV ve düşük PEEP uygulaması ile meydana getirilen VILI tablosunda görülen alveoler yapılarda bozulma, mikroatelektaziler, alveoler septal kalınlaşmalar, alveoler ödem ve nötrofil infiltrasyonunun düşük TV, yüksek PEEP ile belirgin olarak azaldı-ğını bildirmişlerdir. Çalışmamızın sonuçları, gelişebilecek VILI üzerinde KA'nın düşük TV, yüksek PEEP ile elde edilen önleyici etkiyi sağlayacağını göstermiştir.…”
