Effect of the Anatomic Reservoir on Low-Flow Oxygen Delivery Via Nasal Cannula: Constant Flow Versus Pulse Flow With Portable Oxygen Concentrator.

The FIO2 for a nasal cannula with constant flow (CF) depends on the anatomic reservoir (AR), which is affected by changes in frequency and end-expiratory flow. Conversely, pulse flow (PF) devices do not require the AR. The purpose of this study was to compare the FIO2 delivered by a nasal cannula supplied by CF via oxygen tank with that delivered by PF delivered via portable oxygen concentrator. Hypotheses were (1) a lung model of COPD with non-zero end-expiratory flow decreases FIO2 for CF more than for PF...


Impact of Pulmonary Rehabilitation in Patients With Mild COPD.

Pulmonary rehabilitation (PR) is a core component of the management of patients with moderate-to-very-severe COPD. However, as impairments in quadriceps muscle strength and health-related quality of life (HRQOL) are already present in patients with mild COPD, there is a need to investigate whether PR could also be beneficial to these patients. Thus, this study assessed the impact of PR on patients with mild COPD.


A Unidirectional Breathing Pattern Improves Breathing Efficiency in Patients with Severe COPD.

Unidirectional breathing (UB), nose-in mouth-out (NMB) or vice versa, is thought to create PEEP, stabilize small airways, and increase expiratory flow and exhaled tidal volume (VT) in patients with expiratory obstructive disorders. However, the exact mechanism providing the benefits of UB remains unknown. Our hypothesis was that the benefits of UB are achieved mainly through reduction of upper airway dead space.


Nintedanib: A Novel Therapeutic Approach for Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic lung disease with no clear etiology and few therapeutic options. Growth factors that act as mediators in the development of this disease might be important therapeutic targets. Nintedanib is a triple-tyrosine kinase inhibitor and a potent antagonist of growth factors such as platelet-derived growth factor, vascular endothelial growth factor, and basic fibroblast growth factor, and it is currently evaluated in clinical trials as a potent...


A Case of Drug-Induced Interstitial Pneumonia Potentially Related to Quetiapine (Seroquel) Therapy for Behavioral and Psychological Symptoms.

Quetiapine is regarded as an effective and safe treatment for delirium. An 82-year-old man presented with a 1-week history of violent behavior and dizziness accompanied by weakness on the left side of his body. He was diagnosed with acute cerebral cortical infarction and delirium associated with alcohol abuse. After quetiapine treatment, he complained of fever and coughed up sputum, whereas his aggressive behavior improved. His symptoms persisted despite empirical antibiotic treatment. All diagnostic tests...


Inter-Observer Agreement of Spontaneous Breathing Trial Outcome.

Spontaneous breathing trials (SBTs) are a very important test in the weaning process. The trial involves evaluation of multiple objective and subjective variables. These characteristics could lead to variability in interpreting outcomes with important clinical implications. We aimed to measure the inter-observer agreement between respiratory therapists when analyzing SBT outcomes.


Expiratory and Expiratory Plus Inspiratory Muscle Training Improves Respiratory Muscle Strength in Subjects with COPD: Systematic Review.

Inspiratory muscle training (IMT) produces beneficial effects in COPD subjects, but the effects of expiratory muscle training (EMT) and EMT plus IMT in ventilatory training are still unclear. The aim of this study was to systematically review the effects of EMT and EMT plus IMT compared to control groups of COPD subjects.


Evaluation of Adherence to Ambulatory Liquid Oxygen Treatment: Are Commercialized Dual-Pressure Transducers Helpful?

Treatment adherence is widely recognized as a critical problem in long-term oxygen therapy, particularly in ambulatory liquid oxygen (LOX) systems. Adherence-monitoring strategies may be helpful in managing patients. We evaluated subjects' adherence to LOX using VisionOx and compared these results with the subjects' own adherence diaries and self-reported perceptions of use.


A Survey of Extended-Interval Aminoglycoside Dosing Practices in United States Adult Cystic Fibrosis Programs.

The Cystic Fibrosis Foundation recently deemed the use of extended-interval dosing (EID) of aminoglycosides acceptable for the treatment of cystic fibrosis (CF) pulmonary exacerbations. However, current practice across United States adult CF programs and affiliate programs is unknown. The objectives of this research are to characterize the practice trends, dosing strategies, therapeutic drug-monitoring practices, and adverse effect monitoring of the EID of aminoglycosides in the treatment of pulmonary exace...


Noninvasive Ventilation in Severe Acute Asthma.

Noninvasive ventilation (NIV) in severe acute asthma is controversial but may benefit this population by preventing intubation. We report on a 35-year-old male asthma patient who presented to our emergency department via emergency medical services. The patient was responsive, diaphoretic, and breathing at 35 breaths/min on 100% oxygen with bag-mask assistance, with SpO2 88%, heart rate 110-120 beats/min, blood pressure 220/110 mm Hg, and temperature 35.8°C. NIV at 12/5 cm H2O and FIO2 0.40 was applied, and...


Reversed Halo Sign: A Systematic Review.

A reversed halo sign (RHS) is defined as the presence of a focal ring-shaped area of ground-glass opacity within a peripheral rim of consolidation. Although originally described in patients with cryptogenic organizing pneumonia, it has been described with several other noninfectious and infectious diseases, including fungal infections. Thus, it is imperative that a proper diagnosis be established before initiating treatment. In this article, we systematically review the literature (PubMed and Embase) for th...
