BACKGROUND: An exercise modality that has been gaining significant importance in the rehabilitation of subjects with COPD is resistance training. When considering that patients with COPD present alterations in autonomic cardiac modulation caused by the disease itself, it is necessary to investigate the behavior of the autonomic nervous system in relation to this type of exercise. Thus, the objective of this study was to compare the acute effects of resistance training with elastic tubes, elastic bands, and conventional weightlifitng on the behavior of cardiac autonomic modulation in post-exercise recovery in subjects with COPD...

BACKGROUND: Pressure ulcers related to oronasal masks used with noninvasive ventilation (NIV), along with patient discomfort, occur due to improper fit of the mask. We developed a personalized fitting device using a 3-dimensional (3D) scanning solution to prevent the formation of NIV mask-related pressure ulcers. This study aimed to evaluate the effectiveness of the proposed personalized fitting device. METHODS: We conducted a randomized crossover experimental study of 20 healthy participants to study the use of this personalized fitting device between the face and an NIV mask designed with 3D solutions...

BACKGROUND: Different protocols for the sit-to-stand test (STS) are available for assessing functional capacity in COPD. We sought to correlate each protocol of the STS (ie, the 5-repetition [5-rep STS], the 30-s STS, and the 1-min STS) with clinical outcomes in subjects with COPD. We also aimed to compare the 3 protocols of the STS, to verify their association and agreement, and to verify whether the 3 protocols are able to predict functional exercise capacity and physical activity in daily life (PADL)...

BACKGROUND: A new holding chamber was designed to be used with the Aerogen Solo nebulizer to increase the aerosol emitted that reach the patient. The aim of this study was to evaluate the efficacy of this holding chamber with Solo nebulizer and determine its usability with other nebulizers. METHODS: The study was divided into 2 parts. In the first part, aerosol emitted of 1 mL respirable solution (nominal dose of 5000 μg salbutamol), delivered by using the Solo nebulizer, Pro nebulizer, and jet nebulizer, connected to a T-piece or a holding chamber, was determined by using a breathing simulator set to provide a tidal volume of 500 mL, frequency of 15 breaths/min, and the inspiratory-expiratory ratio of 1:1 for adults as the quiet breathing pattern...

BACKGROUND: Congenital diaphragmatic hernia remains a complex disease with significant morbidity and mortality. Hypercarbia is a common derangement in this population, which often requires escalating ventilator support. By decreasing airway turbulence and enhancing CO2 removal, inhaled helium-oxygen mixture (heliox) has the potential to improve ventilation and thereby decrease ventilator support and its associated lung injury. METHODS: Retrospective cohort review of all neonates with congenital diaphragmatic hernia treated at Rady Children's Hospital San Diego during 2011-2015...

BACKGROUND: A normal heart rate reflects the balance between the sympathetic and parasympathetic autonomic nervous system. When the difference between heart rate at the end of an exercise test and after 1 min of recovery, known as the 1-min heart rate recovery, is ≤ 12 beats/min, this may indicate an abnormal delay. We sought to compare physical activity patterns and subjects' functional status with COPD with or without delayed 1-min heart rate recovery after the 6-min walk test (6MWT)...

BACKGROUND: Faster inspiratory pressurization can improve patient-ventilator synchrony and reduce the patient's work of breathing during pressure controlled continuous mandatory (PC-CMV) ventilation. The characteristics of the pressurization ramp settings are not standardized across ventilators from different manufacturers. We performed a bench test of 5 models of ICU ventilators to examine the effects of pressurization ramp settings on the actual pressurization. METHODS: A twin-bellows lung model was used, in which one bellow simulates inspiratory muscle activity and the other simulates an adult normal lung model...

BACKGROUND: Until recently, it has been considered essential to maintain the use of a double-limb circuit in patients with amyotrophic lateral sclerosis (ALS) to avoid rebreathing expired air during invasive mechanical ventilation. Currently, life-sustaining home ventilators can work with a single, lighter circuit that is easier to manage. Our aim was to evaluate the effectiveness and safety of a single-limb circuit with intentional leaks (passive circuit) in comparison with a circuit with an expiratory valve (active circuit), in subjects with ALS who use invasive home ventilation...

BACKGROUND: Recommendations regarding ventilation during cardiopulmonary resuscitation (CPR) are based on a low level of scientific evidence. We hypothesized that practices about ventilation during CPR might be heterogeneous and may differ worldwide. To address this question, we surveyed physicians from several countries on their practices during CPR. METHODS: We used a Web-based opinion survey. Links to the survey were sent by e-mail newsletters and displayed on the Web sites of medical societies involved in CPR practice from December 2013 to March 2014...

BACKGROUND: Transcutaneous monitors are utilized to monitor a patient's respiratory status. Some patients have similar values when comparing transcutaneous carbon dioxide ( P tcCO2 ) values with blood gas analysis, whereas others show extreme variability. A retrospective review of data was performed to determine how accurately P tcCO2 correlated with CO2 values obtained by arterial blood gas (ABG) or capillary blood gas. METHODS: To determine whether P tcCO2 values correlated with ABG or capillary blood gas values, subjects' records were retrospectively reviewed...

BACKGROUND: Tracheostomy is considered to be effective in the respiratory support of mechanically ventilated patients. We studied a single-center experience of surgical tracheostomy in mechanically ventilated patients to describe the demographics, risk factors, and outcomes of early (≤ 14 d after ventilation) versus late surgical tracheostomy (≥ 15 d after ventilation). METHODS: In this retrospective study, we collected demographic data, medical history, timing of surgical tracheostomy in relation to ventilation day, blood test results, preoperative surgical assessment (subjective impression of neck length, difficulty in neck extension, presence of a goiter), intraoperative complications (bleeding > 100 mL, difficulties in cannula insertion), and postoperative morbidities (bleeding, wound infection, fever, inadvertent de-cannulation, and 30-d postoperative mortality rate) of subjects who underwent surgical tracheostomy in a secondary medical center during 2010-2015...

REVIEW
Ashima S Sahni, Lisa Wolfe
Caring for patients with neuromuscular disease (NMD) is challenging. Respiratory care is of the utmost importance because it is a major determinant of quality of life and survival. Noninvasive ventilation (NIV) is one of the few modalities that has shown survival benefit in the NMD patient population. Newer modes with smart technologies are being developed to assist in better ventilation. Some noninvasive methods have shown success in the management of sialorrhea, which is of paramount importance in the initiation of NIV...

REVIEW
Gregory Reychler, Emilie Debier, Olivier Contal, Nicolas Audag
BACKGROUND: Airway clearance techniques are regularly proposed as a part of the treatment in chronic obstructive airway diseases. Intrapulmonary percussive ventilation (IPV) is used as an airway clearance technique in patients affected by excessive lung secretions. The aim of this systematic review is to summarize the physiological and clinical effects related to the use of IPV as an airway clearance technique in chronic obstructive airway diseases. METHODS: This systematic review followed the PRISMA guidelines...

BACKGROUND: Lung ultrasound is increasingly becoming a diagnostic tool in the critical care setting. B-pattern on a lung ultrasound is an artifact composed of multiple B-lines and correlates with interstitial edema. A randomized controlled trial concluded that bedside thoracic ultrasound could predict postextubation distress through changes in lung aeration during a weaning procedure; however, it could not screen patients before performance of a spontaneous breathing trial (SBT). METHODS: We conducted a 2-year, prospective, multicenter, observational study in 2 adult medical-surgical ICUs in southern Brazil...

BACKGROUND: Respiratory complications represent the major cause of death in amyotrophic lateral sclerosis (ALS). Noninvasive respiratory support is the mainstay therapy, but treatment becomes challenging as the disease progresses, possibly due to a malfunctioning larynx, which is the entrance to the airways. We studied laryngeal response patterns to mechanically assisted cough (mechanical insufflation-exsufflation) as ALS progresses. METHODS: This prospective longitudinal study of 13 consecutively included subjects with ALS were followed up during 2011-2016 with repeated tests of lung function, neurological status, and laryngeal responses to mechanical insufflation-exsufflation using video-recorded flexible transnasal fiberoptic laryngoscopy...
