Satisfactory functional outcomes following bronchoscopic lung volume reduction (BLVR) using endobronchial valves (EBVs) depend on the absence of collateral ventilation (CV) between the target and adjunct lobes. The Chartis system has proven to be useful for determining whether CV is present or absent, but this system can also erroneously indicate the absence of CV, which can lead to BLVR failure. Here, we describe low-flow Chartis phenotype in the target lobe resulted in difficult judgment of existence of CV...

BACKGROUND: Volutrauma has been established as the key factor in ventilator-induced lung injury and can only be avoided if tidal volume (VT) is accurately displayed and delivered. The purpose of this study was to investigate the accuracy of displayed exhaled VT in a ventilator commonly used in small infants with or without a proximal flow sensor and using 3 methods to achieve a target VT in both a healthy and lung-injured neonatal pig model. METHODS: This was a prospective animal study utilizing 8 male pigs, approximately 2...

BACKGROUND: Volume-targeted ventilation is increasingly used in low birthweight infants because of the potential for reducing volutrauma and avoiding hypocapnea. However, it is not known what level of air leak is acceptable during neonatal volume-targeted ventilation when leak compensation is activated concurrently. METHODS: Four ICU ventilators (Servo-i, PB980, V500, and Avea) were compared in available invasive volume-targeted ventilation modes (pressure control continuous spontaneous ventilation [PC-CSV] and pressure control continuous mandatory ventilation [PC-CMV])...

This article provides a narrative review of lung-protective ventilatory strategies (LPVS) in intubated preterm infants with RDS. A description of strategies is followed by results on short-and long-term respiratory and neurodevelopmental outcomes. Strategies will include patient-triggered or synchronized ventilation, volume targeted ventilation, the technique of intubation, surfactant administration and rapid extubation to NCPAP (INSURE), the open lung concept, strategies of high-frequency ventilation, and permissive hypercapnia...

BACKGROUND: Mechanical ventilation can cause lung endothelial barrier failure and inflammation cumulating in ventilator-induced lung injury. Yet, underlying mechanotransduction mechanisms remain unclear. Here, the authors tested the hypothesis that activation of the mechanosensitive Ca channel transient receptor potential vanilloid (TRPV4) by serum glucocorticoid-regulated kinase (SGK) 1 may drive the development of ventilator-induced lung injury. METHODS: Mice (total n = 54) were ventilated for 2 h with low (7 ml/kg) or high (20 ml/kg) tidal volumes and assessed for signs of ventilator-induced lung injury...

BACKGROUND AND PURPOSE: The objective of this study was to compare the latest respiratory motion-management strategies, namely the internal-target-volume (ITV) concept, the mid-ventilation (MidV) principle, respiratory gating and dynamic couch tracking. MATERIALS AND METHODS: An anthropomorphic, deformable and dynamic lung phantom was used for the dosimetric validation of these techniques. Stereotactic treatments were adapted to match the techniques and five distinct respiration patterns, and delivered to the phantom while radiographic film measurements were taken inside the tumor...

BACKGROUND: Volume-targeted noninvasive ventilation (VT-NIV), a hybrid mode that delivers a preset target tidal volume (VT) through the automated adjustment of pressure support, could guarantee a relatively constant target VT over pressure-limited noninvasive ventilation (PL-NIV) with fixed-level pressure support. Whether VT-NIV is more effective in improving ventilatory status in subjects with acute hypercapnic respiratory failure (AHRF) remains unclear. Our aim was to verify whether, in comparison with PL-NIV, VT-NIV would be more effective in correcting hypercapnia, hence reducing the need for intubation and improving survival in subjects with AHRF...

RATIONALE: Controlled mechanical ventilation is used to deliver lung-protective ventilation in patients with acute respiratory distress syndrome. Despite recognized benefits, such as preserved diaphragm activity, partial support ventilation modes may be incompatible with lung-protective ventilation due to high tidal volume and high transpulmonary pressure. As an alternative to high dose sedatives and controlled mechanical ventilation, pharmacologically induced neuromechanical uncoupling of the diaphragm should facilitate lung-protective ventilation under partial support modes...

BACKGROUND AND OBJECTIVES: This study's main aim was to observe the effects of a fibre-enriched nutrition solution on requisite feeding volume, which is directly proportional to energy intake in mechanically ventilated patients with enteral nutrition. METHODS AND STUDY DESIGN: Some 120 patients who required mechanical ventilation and enteral nutrition with a nasogastric tube were studied.

OBJECTIVE: To explore the effect of Smad4 on the extracellular matrix remodeling in ventilator-induced lung injury (VILI). METHODS: We randomized 24 C57BL/6 mice to 4 groups for treatment (n=6/group): control, ventilation, non-targeted (scramble) lentivirus transfection plus ventilation, and Smad4 small interfering RNA (siRNA) lentivirus transfection plus ventilation. Lentivirus was delivered by intranasal instillation. Four weeks later, the 3 ventilated groups underwent high tidal volume (VT 40mL/kg) ventilation to induce lung injury...

For patients with lung cancer undergoing curative intent radiotherapy, functional lung imaging can be incorporated into treatment planning to modify the dose distribution within non-target volume lung by differentiation of lung regions that are functionally defective or viable. This concept of functional image-guided lung avoidance treatment planning has been investigated with several imaging modalities, primarily single photon emission computed tomography (SPECT), but also hyperpolarised gas magnetic resonance (MR) imaging, positron emission tomography (PET) and computed tomography (CT)-based measures of lung biomechanics...

BACKGROUND: Mechanical ventilation is an essential therapy in the treatment of respiratory failure in preterm infants. However, optimal ventilation strategy continues to be difficult to define.

RATIONALE: Although increasingly recommended, compliance with low Vt ventilation remains suboptimal. Dyssynchrony induced by low Vts may be a reason for it. OBJECTIVES: To determine the effect of Vt size, and of the ventilator mode used for its delivery (volume vs. pressure control), on the magnitude of patient-ventilator dyssynchrony in patients with or at risk for acute respiratory distress syndrome. METHODS: Nineteen mechanically ventilated patients underwent six consecutive ventilatory conditions: three on volume assist-control (VC) mode, each with set Vt of 6, 7...

RATIONALE: Endobronchial valves (EBV) have been successfully used in patients with severe heterogeneous emphysema to improve lung physiology. Limited available data suggests that EBVs are also effective in homogeneous emphysema. OBJECTIVE: To evaluate the efficacy and safety of EBV in patients with homogeneous emphysema with absence of collateral ventilation assessed by Chartis. METHODS: Prospective, multicenter 1:1 randomized controlled trial of EBV plus standard-of-care (SoC) or (SoC) alone...

BACKGROUND: Bronchoscopic lung volume reduction using one-way endobronchial valves (EBVs) has been proven to be effective in patients with severe emphysema. However, the selection of patients without collateral ventilation prior to treatment is critical for procedural success. Collateral ventilation can be assessed directly with the Chartis system or indirectly using computed tomography (CT) fissure analysis. OBJECTIVES: We retrospectively evaluated the diagnostic value of a combination of the quantitative CT interlobar fissure completeness score (FCS) and Chartis in predicting responders to EBV therapy...

BACKGROUND: Randomized controlled trials indicate that significant lung volume reduction (ELVR) can be obtained with Zephyr® valves by occluding the target lobe in the absence of collateral ventilation, leading to relevant functional benefits in advanced emphysema patients. OBJECTIVES: To observe the long-term effects of endobronchial valve (EBV) implantation in emphysema patients screened by Chartis assessment in the context of daily pulmonology practice. METHODS: The LIVE Study is a prospective, observational, open-label, single-arm, multicenter trial conducted in Germany...
