Respiratory system as the main determinant of dyspnea in patients with pulmonary hypertension.

Pulm Circ 2022 Jan 23;12(1):e12060. Epub 2022 Mar 23.

Department of Intensive Care Medicine, University Hospital of Heraklion, Medical School University of Crete Heraklion Crete Greece.

Dyspnea on exertion is a devastating symptom, commonly observed in patients with pulmonary hypertension (PH). The pathophysiology of dyspnea in these patients has been mainly attributed to cardiovascular determinants and isolated abnormalities of the respiratory system during exercise, neglecting the contribution of the control of the breathing system. The aim of this review is to provide a novel approach to the interpretation of dyspnea in patients with PH, focused on the impact of the control of the breathing system during exercise. Read More

Noninvasive Oxygenation in Patients with Acute Respiratory Failure: Current Perspectives.

Int J Gen Med 2022 7;15:3121-3132. Epub 2022 Apr 7.

Centre Hospitalier Universitaire de Poitiers, Médecine Intensive Réanimation, Poitiers, France.

Purpose Of Review: High-flow nasal oxygen and noninvasive ventilation are two alternative strategies to standard oxygen in the management of acute respiratory failure.

Discussion: Although high-flow nasal oxygen has gained major popularity in ICUs due to its simplicity of application, good comfort for patients, efficiency in improving oxygenation and promising results in patients with acute hypoxemic respiratory failure, further large clinical trials are needed to confirm its superiority over standard oxygen. Non-invasive ventilation may have deleterious effects, especially in patients exerting strong inspiratory efforts, and no current recommendations support its use in this setting. Read More

Utility of non-invasive synchronized intermittent mandatory ventilation in acute cardiogenic pulmonary edema.

Am J Emerg Med 2022 Jun 27;56:71-76. Epub 2022 Mar 27.

Department of Emergency Medicine, Faculty of Medicine Ataturk University, Istanbul, Turkey.

Backgrounds: Acute cardiogenic pulmonary edema (ACPE), one of the outcomes of acute heart failure (AHF), is a common reason in a critical condition with respiratory distress. Non-invasive synchronized intermittent mandatory ventilation(nSIMV) mode, which includes inspiratory pressure in addition to positive end expiratory pressure with/without pressure support provided in the non-invasive continuous positive airway pressure plus/pressure support(nCPAP/PS) mode can be effective in hypercarbia and the associated changes in consciousness. This study aimed to demonstrate the efficacy of nSIMV in ACPE. Read More

Progressive pulmonary fibrosis due to diffuse alveolar damage in a COVID-19-infected autopsy case.

Respirol Case Rep 2022 Apr 16;10(4):e0934. Epub 2022 Mar 16.

Department of Pulmonary Medicine St. Luke's International Hospital Tokyo Japan.

We encountered a patient with severe coronavirus disease 2019 (COVID-19)-related pneumonia, who died of progressive respiratory acidosis after 2 months of treatment with mechanical ventilation. The autopsy revealed diffuse alveolar damage (DAD) without any active signs of fungal or bacterial infections, suggesting prolonged and over-activated immune responses against COVID-19 infection. When COVID-19 patients develop acute respiratory distress syndrome, it is essential to remember that the infection can progress to DAD a few months after the disease onset. Read More
