Dead space ventilation promotes alveolar hypocapnia reducing surfactant secretion by altering mitochondrial function.

Thorax 2019 Jan 12. Epub 2019 Jan 12.

Department of Anesthesiology, University Hospital Hamburg-Eppendorf, Hamburg, Germany.

Background: In acute respiratory distress syndrome (ARDS), pulmonary perfusion failure increases physiologic dead space ventilation (V/V), leading to a decline of the alveolar CO concentration [CO]. Although it has been shown that alveolar hypocapnia contributes to formation of atelectasis and surfactant depletion, a typical complication in ARDS, the underlying mechanism has not been elucidated so far.

Methods: In isolated perfused rat lungs, cytosolic or mitochondrial Ca concentrations ([Ca] or [Ca], respectively) of alveolar epithelial cells (AECs), surfactant secretion and the projected area of alveoli were quantified by real-time fluorescence or bright-field imaging (n=3-7 per group).

The role of ultrasound lung artefacts in the diagnosis of respiratory diseases.

Expert Rev Respir Med 2019 Jan 8. Epub 2019 Jan 8.

d Department of Information Engineering and Computer Science , University of Trento , Trento , Italy.

Introduction: Thoracic ultrasound is employed for the diagnosis of many thoracic diseases and is an accepted detection tool of pleural effusions, atelectasis, pneumothorax and pneumonia. However, the use of ultrasound for the evaluation of parenchymal lung disease, when the organ is still aerated, is a relatively new application. Areas covered: The diagnosis of a normal lung and the differentiation between a normally aerated lung and a lung with interstitial pathology is based on the interpretation of ultrasound artifacts universally known as A and B-Lines.

Ventilator-associated events versus ventilator-associated respiratory infections-moving into a new paradigm or merging both concepts, instead?

Ann Transl Med 2018 Nov;6(21):425

Vall d'Hebron Institut of Research, Barcelona, Spain.

Despite ventilator-associated respiratory infections (VARI) are reported as the most common and fatal complications related to mechanical ventilation (MV), they are not the unique occurrences. The new classification of ventilator-associated events (VAE) proposed by the centers for disease control and prevention (CDC) enhance the spectra of complications due to MV including both infection-related and non-infectious events. Both VAEs and VARIs are associated with prolonged duration of MV, longer stay in hospital and in the intensive care unit (ICU) and more antibiotic consumption, nonetheless patients with VAEs have worst outcomes.

Intermittent Hypoxia Activates Duration-Dependent Protective and Injurious Mechanisms in Mouse Lung Endothelial Cells.

Front Physiol 2018 6;9:1754. Epub 2018 Dec 6.

Department of Anaesthesia, General Intensive Care and Pain Management, Medical University of Vienna, Vienna, Austria.

Intermittent hypoxia is a major factor in clinical conditions like the obstructive sleep apnea syndrome or the cyclic recruitment and derecruitment of atelectasis in acute respiratory distress syndrome and positive pressure mechanical ventilation. investigations of the direct impact of intermittent hypoxia are frequently hampered by multiple co-morbidities of patients. Therefore, cell culture experiments are important model systems to elucidate molecular mechanisms that are involved in the cellular response to alternating oxygen conditions and could represent future targets for tailored therapies.

Revisiting atelectasis in lung units with low ventilation/perfusion ratios.

J Appl Physiol (1985) 2018 Dec 20. Epub 2018 Dec 20.

Anesthesia, Critical Care and Pain Medicine, Beth Israel Deaconess Medical Center 330 Brookline Ave DA717 Boston MA 02215, United States.

Patients on high inspired O concentrations are at risk of atelectasis, a problem that has been quantitatively assessed using analysis of V̇/Q̇ equations. This approach ignores the potential of the elastic properties of the lung to support gas exchange through "apneic" oxygenation in units with no tidal ventilation, and is based on an error in the conservation of mass equations. To fill this gap, we correct the error and compare the pressure drops associated with apneic gas exchange with the pressure differences that can be supported by lung recoil. Read More

Lobar atelectasis (or collapse) is an exceedingly common, rather predictable, and potentially pathogenic companion to many forms of acute illness, postoperative care, and chronic debility. Readily diagnosed by using routine chest imaging and bedside ultrasound, the consequences from lobar collapse may be minor or serious, depending on extent, mechanism, patient vulnerability, abruptness of onset, effectiveness of hypoxic vasoconstriction, and compensatory reserves. Measures taken to reduce secretion burden, assure adequate secretion clearance, maintain upright positioning, reverse lung compression, and sustain lung expansion accord with a logical physiologic rationale.

Limiting ventilator-associated complications in ICU intubated subjects: strategies to prevent ventilator-associated events and improve outcomes.

Expert Rev Respir Med 2018 Nov 21:1-14. Epub 2018 Nov 21.

d Clinical Research/epidemiology In Pneumonia & Sepsis , Vall d'Hebron Institut of Research & Centro de Investigacion Biomedica en Red (CIBERES) , Barcelona , Spain.

Introduction: Intubation is required to maintain the airways in comatose patients and enhance oxygenation in hypoxemic or ventilation in hypercapnic subjects. Recently, the Centers of Disease Control (CDC) created new surveillance definitions designed to identify complications associated with poor outcomes. Areas covered: The new framework proposed by CDC, Ventilator-Associated Events (VAE), has a range of definitions encompassing Ventilator-Associated Conditions (VAC), Infection-related Ventilator-Associated Complications (IVAC), or Possible Ventilator-Associated Pneumonia - suggesting replacing the traditional definitions of Ventilator-Associated Tracheobronchitis (VAT) and Ventilator-Associated Pneumonia (VAP).
