The mechanism of lung volume change during mechanical ventilation.
To understand ventilator-induced lung injury (VILI) during positive pressure ventilation, mechanisms of normal alveolar mechanics must first be established. Isotropic "balloonlike" alveolar volume (VA) change has been viewed as the prevailing mechanism of normal lung volume (VL) changes. We hypothesized that change in VL is predominantly caused by alveolar recruitment-derecruitment (R/D). Fifte...
متن کاملBasic invasive mechanical ventilation.
Invasive mechanical ventilation is a lifesaving intervention for patients with respiratory failure. The most commonly used modes of mechanical ventilation are assist-control, synchronized intermittent mandatory ventilation, and pressure support ventilation. When employed as a diagnostic tool, the ventilator provides data on the static compliance of the respiratory system and airway resistance. ...
متن کاملEstimating lung volume during high frequency ventilation
The primary goals of lung ventilation are to bring oxygen into the alveoli from where it can enter the blood, and to eliminate carbon dioxide dissolved in the blood. Since CO2 is much more soluble in blood than oxygen, O2 transport is diffusion-limited and a large alveolar surface area is the primary factor controlling its delivery. CO2 transport is flow-limited, so that efficient gas transport...
متن کاملInvasive and Non-invasive Mechanical Ventilation in Pediatric Patients with COVID-19: A Systematic Review
Background and purpose: In the last months of 2019, the new coronavirus infection (COVID-19) spread worldwide. This study investigated the need for mechanical ventilation in children who were admitted for COVID-19. Materials and methods: This article provides a systematic review of studies about children with COVID-19 requiring invasive or non-invasive mechanical ventilation. Electronic databa...
متن کاملPressure versus volume controlled modes in invasive mechanical ventilation.
The first generation of mechanical ventilators were controlled and cycled by pressure. Unfortunately, they did not allow control of the delivered tidal volume under changes in the dynamics of the respiratory system. This led to a second generation of ventilators that allowed volume control, hence favoring the ventilatory strategy based on normalization of the arterial gases. Studies conducted i...
