non invasive ventilation in copd

BACKGROUND: The prevalence of invasive pulmonary aspergillosis (IPA) among patients with chronic obstructive pulmonary disease (COPD) is steadily increasing, leading to high mortality. Although early diagnosis can significantly reduce mortality, the efficacy of current diagnostic methods is limited. Consequently, there is a need for novel approaches for early IPA detection. METHODS: This retrospective study involved 383 hospitalized COPD patients with GOLD stages III and IV...

UNLABELLED: OObjective: Prognostic models aid clinical practice with decision-making on treatment and hospitalization in exacerbation of chronic obstructive lung disease (ECOPD). Although there are many studies with prognostic models, diagnostic accuracy is variable within and between models. SUBJECTS AND METHODS: We compared prognostic performance of the BAP65 score, DECAF score, PEARL score and modified early warning score (MEWS) in hospitalized patients with ECOPD, to estimate ventilatory support need...

Acute respiratory failure (ARF) is a leading cause, along with sepsis, of admission to the intensive care unit (ICU) of patients with active cancer. Presenting variable clinical severity, ARF in onco-hematological patients has differing etiologies, primarily represented by possibly opportunistic acute infectious pneumonia (de novo hypoxemic ARF), and decompensation in chronic cardiac or respiratory diseases (e.g., acute pulmonary edema or exacerbated chronic obstructive pulmonary disease). In these patients, orotracheal intubation is associated with a doubled risk of in-hospital mortality...

BACKGROUND: Heartbeat-based cross-sectional area (CSA) changes in the right main pulmonary artery (MPA), which reflects its distensibility associated with pulmonary hypertension, can be measured using dynamic ventilation computed tomography (DVCT) in patients with and without chronic obstructive pulmonary disease (COPD) during respiratory dynamics. We investigated the relationship between MPA distensibility (MPAD) and respiratory function and how heartbeat-based CSA is related to spirometry, mean lung density (MLD), and patient characteristics...

Background: Home non-invasive positive pressure ventilation (NPPV) may improve chronic hypercarbia in COPD and patient important outcomes. The efficacy of home high flow nasal cannula (HFNC) as an alternative is unclear. Methods: We searched MEDLINE, EMBASE, Cochrane CENTRAL, SCOPUS, and Clinicaltrials.gov for randomized trials of patients from inception to March 31st and updated the search on July 14, 2023. We performed a frequentist network meta-analysis and assessed the certainty of the evidence using the GRADE approach...

BACKGROUND: Mechanical ventilation is commonly used for managing respiratory failure in chronic obstructive pulmonary disease (COPD) patients, but weaning patients off ventilator support can be challenging and associated with complications. While many patients respond well to Non-invasive ventilation (NIV), a significant proportion may not respond as favourably. We aimed to assess whether high-flow nasal cannula (HFNC) is equally effective as NIV in reducing extubation failure among previously intubated COPD patients...

This study compared the treatment outcomes of acute exacerbation of COPD (AECOPD) at an academic tertiary care emergency department before and during the COVID-19 pandemic. Analyzing data from 976 patients, our study showed a significant surge in overall respiratory therapy interventions amidst the noticeable decline in the total number of AECOPD cases during the pandemic. The marked increase in the utilization of non-invasive ventilation (NIV) was particularly important, soaring from 12% to 18% during the pandemic...

This state-of-the-art review provides an overview of the history of home mechanical ventilation (HMV), including early descriptions of mechanical ventilation from ancient and Renaissance perspectives and the mass development of ventilators designed for long-term use during the poliomyelitis epidemic. Seminal data from key clinical trials supports the application of HMV in certain patients with chronic obstructive pulmonary disease, neuromuscular disease and obesity-related respiratory failure. Innovative engineering coupled with refined physiological understanding now permits widespread delivery of home mechanical ventilation to a global population, using portable devices with advanced ventilatory modes and telemonitoring capabilities...

OBJECTIVE: Ventilator-assisted preoxygenation (VAPOX) is a method of preoxygenation and apnoeic ventilation which has been tried in hospital setting. We aimed to describe VAPOX during intubation of critically unwell patients in aeromedical retrieval setting. METHODS: Retrospective observational study of VAPOX performed at LifeFlight Retrieval Medicine (LRM) between January 2018 and December 2022 across Queensland, Australia. Demographic and clinical data were recorded...

Chilaiditi syndrome (CS) is an uncommon case of the asymptomatic radiographic finding of an intestinal loop between the liver and the diaphragm. The most crucial phases in the diagnosis process are a thorough physical examination and precise imaging, particularly in challenging disorders such as CS. The presence of free air under the right hemidiaphragm in this syndrome, the diagnosis of which is based on radiographic imaging, might direct the start of treatment without the need for surgical intervention. An 86-year-old man, with asthma and chronic obstructive pulmonary disease (COPD) was checked out in our hospital's emergency department (ED) after experiencing nausea and vomiting...

BACKGROUND: While the prevalence of severe cases and mortality rate of coronavirus disease 2019 (COVID-19) appear to be reducing, the clinical characteristics and severity of hospitalized patients with asthma and COVID-19 remain largely unknown. This study aimed to examine the association of asthma with COVID-19 severity and mortality risk. METHODS: Data from the Japanese COVID-19 Registry Database were used to investigate the association between COVID-19 and asthma...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) poses a significant global health burden. Finding effective interventions for COPD is crucial to alleviating this health burden and enhancing patient outcomes and quality of life. OBJECTIVE: This study aimed to evaluate the therapeutic efficacy of the combination of non-invasive ventilation and naloxone in the management of acute respiratory failure among patients with COPD. METHODS: A retrospective analysis was conducted on the clinical data of 102 COPD patients experiencing acute respiratory failure who were treated at our hospital between October 2020 and October 2022...

BACKGROUND AND OBJECTIVE: Non-invasive ventilation (NIV) improves survival of patients with chronic respiratory failure (CRF). Most often, pressure settings are made to normalize arterial blood gases. However, this objective is not always achieved due to intolerance to increased pressure or poor compliance. Few studies have assessed the effect of persistent hypercapnia on ventilated patients' survival. Data from the Pays de la Loire Respiratory Health Research Institute cohort were analyzed to answer this question...

When administered as first-line intervention to patients admitted with acute hypercapnic respiratory failure secondary to chronic obstructive pulmonary disease exacerbation in conjunction with guideline recommended therapies, noninvasive ventilation (NIV) has been shown to reduce mortality and endotracheal intubation. Opportunities to increase uptake of NIV continue to exist despite inclusion of this therapy in clinical guidelines. Identifying patients appropriate for NIV, and subsequently providing close monitoring to determine an improvement in clinical condition involves a team consisting of physician, nurse and respiratory therapist in institutions that successfully implement NIV...

OBJECTIVE: To clarify the application effect of information-guided enteral nutrition-associated diarrhea (ENAD) management process in patients with chronic obstructive pulmonary disease (COPD) undergoing non-invasive assisted ventilation. METHODS: A mixed cohort study of pre- and post-control was conducted. Thirty-nine patients with COPD who were admitted to the emergency intensive care unit (ICU) of Huzhou First People's Hospital from July 1, 2021 to July 31, 2022 were enrolled...

BACKGROUND: A myriad of early warning scores (EWSs) exist, yet there is a need to identify the most clinically valid score to be used in prehospital respiratory assessments to estimate short-term and midterm mortality, intensive-care unit admission, and airway management in life-threatening acute respiratory distress. METHODS: This is a prospective, observational, multicentre, ambulance-based, external validation study performed in 44 ambulance services and four hospitals across three Spanish provinces (ie, Salamanca, Segovia, and Valladolid)...

Hypercapnia is commonly encountered by general and specialist respiratory clinicians. Patients at risk of developing hypercapnic respiratory failure include those with chronic obstructive pulmonary disease (COPD), obesity and neuromuscular disease. Such patients may present to clinicians acutely unwell on the acute medical take or during an inpatient deterioration, or be identified in the stable outpatient setting. In this review, we provide a practical guide to develop clinicians' knowledge, skills and confidence in promptly recognising and managing hypercapnic respiratory failure, and to promote national ventilation quality standards to encourage consistent delivery of high-quality care and optimise outcomes for patients...

There is increasing evidence that long-term NIV (LT-NIV) can improve outcomes in individuals with severe, hypercapnic COPD. Though the evidence remains uncluear in some aspects, LT-NIV appears to be able to improve patient-related and physiological outcomes like dyspnea, FEV1, PCO2 , and also reduce rehospitalizations and mortality. Efficacy is generally associated with reduction in PCO2 . To achieve this, an adequate interface (mask) is essential, as are appropriate ventilation settings that target the specific respiratory physiology of COPD...

BACKGROUND: Patients with severe chronic obstructive pulmonary disease (COPD) could have palliative care (PC) needs because of unmet needs such as dyspnoea. This may lead to anxiety and may have an impact on patients' ability to perform daily activities of living. PC can be started when patients with COPD have unmet needs and can be provided alongside disease-modifying therapies. Non-invasive ventilation (NIV) could be an important measure to manage dyspnoea in patients with COPD in need of PC...
