Case Reports: Bronchial Mucosal Vasculature Is Also Involved in the Acute Vascular Distress Syndrome of COVID-19.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which targets the pulmonary vasculature is supposed to induce an intrapulmonary right to left shunt with an increased pulmonary blood flow. We report here what may be, to the best of our knowledge, the first videoendoscopic descriptions of an hypervascularization of the bronchial mucosa in two patients hospitalized for coronavirus disease 2019 (COVID-19) pneumonia. Two patients, 27- and 37-year-old, were addressed to our Pneumology department for suspicion of COVID-19 pneumonia.

Dissociation between the clinical course and chest imaging in severe COVID-19 pneumonia: A series of five cases.

Background: Although an RT-PCR test is the "gold standard" tool for diagnosing an infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), chest imaging can be used to support a diagnosis of coronavirus disease 2019 (COVID-19) - albeit with fairly low specificity. However, if the chest imaging findings do not faithfully reflect the patient's clinical course, one can question the rationale for relying on these imaging data in the diagnosis of COVID-19.

Aims: To compare clinical courses with changes over time in chest imaging findings among patients admitted to an ICU for severe COVID-19 pneumonia.

Pure SARS-CoV-2 related AVDS (Acute Vascular Distress Syndrome).

Background: SARS-CoV-2 virus which targets the pulmonary vasculature is supposed to induce an intrapulmonary right to left shunt with an increased pulmonary blood flow. Such vascular injury is difficult to observe because it is hidden by the concomitant lung injury. We report here what may be, to the best of our knowledge, the first case of a pure Covid-19 related Acute Vascular Distress Syndrome (AVDS).

CPAP Added to Oxygen Administration Avoid Intubation in Acute Respiratory Distress in COVID-19 Pneumonia. Case Report.

It was recently described that COVID-19 pneumonia patients had an atypical form of the ARDS syndrome and required gentle ventilation. We report here on benefits of CPAP treatment in a patient with COVID-19 pneumonia. A 63-year-old patient of African origin presented to the emergency room with COVID-19 pneumonia.

Effect of changes in periodic limb movements under cpap on adherence and long term compliance in obstructive sleep apnea.

Purpose of the study Periodic leg movements (PLMs) are found in 30% of patients suffering from OSA. Under CPAP, we observed that PLMs can increase, decrease, or remain unchanged. The predictors of these changes are not well established.

Impact of purchasing the CPAP device on acceptance and long-term adherence: a Belgian model.

Rationale: In Belgium, patients with moderate to severe OSA (AHI > 20) who show less than 30 micro-arousals per hour slept (MAI) cannot benefit from CPAP refund by the social security (SS).

Objectives: To assess the influence of reimbursement on CPAP acceptance, and long-term adherence.

Methods: OSA patients (AHI > 20) were included regardless of MAI.

Sleep apnoea and driving risk: the need for regulation.

Obstructive sleep apnoea syndrome (OSAS) is a highly prevalent chronic respiratory disorder with prevalence among adult males of ≥10%. The most common daytime symptom associated with OSAS is excessive sleepiness, which in more severe manifestations can result in sleepiness at the wheel while driving and probably contributes to the substantial increase in accident risk among patients with OSAS. Fortunately, current evidence indicates that successful therapy of OSAS, particularly with continuous positive airway pressure, can bring the accident risk down to levels similar to an equivalent general population.

Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is a very frequent affliction that affects about 1-5% of the adult population in its severe form. Continuous positive airway pressure (CPAP) is the most commonly used treatment and is highly effective, but its use is limited by low long-term adherence rates and overall poor acceptance among the patients. Therefore, there is a need for developing alternative approaches to OSA treatment, including a more 'natural' concept of maintaining an open airway through neuromodulation.

Driving habits and risk factors for traffic accidents among sleep apnea patients--a European multi-centre cohort study.

Obstructive sleep apnea is associated with increased motor vehicle accident risk, and improved detection of patients at risk is of importance. The present study addresses potential risk factors in the European Sleep Apnea Database and includes patients with suspected obstructive sleep apnea [n = 8476, age 51.5 (12.

[Proposal for a systematic analysis of polygraphy or polysomnography for identifying and scoring abnormal events occurring during non-invasive ventilation].

Non-invasive ventilation (NIV) is recognised as an effective treatment for chronic hypercapnic respiratory failure. Monitoring NIV during sleep may be preferable to daytime assessment. This paper reports the findings of an international consensus group, which systematically analysed nocturnal polygraphic or polysomnographic tracings recorded with either volume-cycled or pressure-cycled ventilators.

[Ventilator modes and settings during non-invasive ventilation: effects on respiratory events and implications for their identification. 2011].

Compared with invasive ventilation, non-invasive ventilation (NIV) has two unique characteristics: its non-hermetic nature and the fact that the ventilator-lung assembly cannot be considered as a single-compartment model because of the presence of variable resistance represented by the upper airways. When NIV is initiated, the ventilator settings are determined empirically based on clinical evaluation and blood gas variations. However, NIV is predominantly applied during sleep.
