Although the optimal ventilation strategy is unknown for patients placed on extracorporeal support, there are increasing reports of extubation being used. Our objective is to describe the change in ventilation strategies and use of tracheostomy and bronchoscopy practices among extracorporeal membrane oxygenation (ECMO) centers across the world. A descriptive, cross-sectional 22 item survey of neonatal, pediatric, and adult ECMO centers was used to evaluate ventilator strategies, extubation, bronchoscopy, and tracheostomy practices...

BACKGROUND: Patients receiving noninvasive ventilation (NIV) may benefit from medical aerosol, but most guidance on dosing with different aerosol devices is limited to in-vitro studies. The study was designed to in-vitro, ex-vivo, and in-vivo compare aerosol delivery during bilevel NIV with three types of aerosol generators: metered dose inhaler with AeroChamber-MV spacer (AC), Aerogen Pro vibrating mesh nebulizer (PRO), and Sidestream jet nebulizer (SIDE). MATERIALS AND METHOD: A bilevel ventilator with dry single limb circuit and fixed expiratory port was set in spontaneous mode with initial inspiratory and expiratory pressures of 20 and 5 cmH20, 1:3 inspiratory-expiratory ratio, and 15 breaths...

BACKGROUND: Previous randomised trials and meta-analyses have shown that nasal continuous positive airway pressure (NCPAP) is a useful method for providing respiratory support after extubation. However, this treatment sometimes 'fails' in infants, and they may require endotracheal re-intubation with its attendant risks and expense. Nasal intermittent positive pressure ventilation (NIPPV) can augment NCPAP by delivering ventilator breaths via nasal prongs. Older children and adults with chronic respiratory failure benefit from NIPPV, and the technique has been applied to neonates...

Preoxygenation before anesthetic induction and tracheal intubation is a widely accepted maneuver, designed to increase the body oxygen stores and thereby delay the onset of arterial hemoglobin desaturation during apnea. Because difficulties with ventilation and intubation are unpredictable, the need for preoxygenation is desirable in all patients. During emergence from anesthesia, residual effects of anesthetics and inadequate reversal of neuromuscular blockade can lead to hypoventilation, hypoxemia, and loss of airway patency...

OBJECTIVE: In paediatric moderate-to-severe asthmatics, there is significant bronchospasm, airway obstruction, air trapping causing severe hyperinflation with more positive intraplural pressure preventing passive air movement. These effects cause an increased respiratory rate (RR), less airflow and shortened inspiratory breath time. In certain asthmatics, aerosols are ineffective due to their inadequate ventilation. Bilevel positive airway pressure (BiPAP) in acute paediatric asthmatics can be an effective treatment...

BACKGROUND: Hospitalization of patients with chronic obstructive pulmonary disease creates a huge healthcare burden. Positive airway pressure therapy is sometimes used in patients with chronic obstructive pulmonary disease, but the possible impact on hospitalization risk remains controversial. We studied the hospitalization risk of patients with chronic obstructive pulmonary disease before and after initiation of various positive airway pressure therapies in a "real-world" bioinformatics study...

Asthmatic children are at risk for respiratory failure and should be appropriately treated before transport. The objectives were to find out if the Pediatric Advanced Life Support guidelines for asthma treatment were followed in the emergency department (ED); to determine if additional treatment during transport or within the first 2 hours of admission was needed; and to compare the management of intubated asthmatics by the ED, transport team, and the intensive care unit (ICU) physician. The records for children diagnosed with acute asthma over 7 years who were transported by the intensive care transport team were reviewed...

Noninvasive ventilation (NIV) as an adjunct strategy for increasing exercise tolerance has been widely investigated in patients with pulmonary diseases. To our knowledge, there are no studies that have used NIV during exercise in patients with decompensated heart failure (HF). The aim of this study was to evaluate the effects of NIV on exercise tolerance in hospitalized patients with decompensated HF. Thirteen patients (77 ± 15 years) with a mean left ventricular ejection fraction of 35 ± 15% were included...

Objective: Evidence indicates that behavioral or drug therapy may not target underlying pathophysiologic mechanisms for chronic insomnia, possibly due to previously unrecognized high rates (30%-90%) of sleep apnea in chronic insomnia patients. Although treatment studies with positive airway pressure (PAP) demonstrate decreased severity of chronic sleep maintenance insomnia in patients with co-occurring sleep apnea, sleep-onset insomnia has not shown similar results. We hypothesized advanced PAP technology would be associated with decreased sleep-onset insomnia severity in a sample of predominantly psychiatric patients with comorbid sleep apnea...

Positive airway pressure (PAP) is considered first-line therapy for moderate to severe obstructive sleep apnea and may also be considered for mild obstructive sleep apnea, particularly if it is symptomatic or there are concomitant cardiovascular disorders. Continuous PAP is most commonly used. Other modes, such as bilevel airway pressure, autotitrating positive airway pressure, average volume assured pressure support, and adaptive support ventilation, play important roles in the management of sleep-related breathing disorders...

Importance: Heated, humidified high-flow nasal cannula (HHHFNC) has gained increasing popularity as respiratory support for newborn infants thanks to ease of use and improved patient comfort. However, its role as primary therapy for respiratory distress syndrome (RDS) of prematurity needs to be further elucidated by large, randomized clinical trials. Objective: To determine whether HHHFNC provides respiratory support noninferior to nasal continuous positive airway pressure (nCPAP) or bilevel nCPAP (BiPAP) as a primary approach to RDS in infants older than 28 weeks' gestational age (GA)...

UNLABELLED: Backround: Coupling nebulization with noninvasive ventilation (NIV) has been shown to be effective in patients with respiratory diseases. However, a breath-synchronized nebulization option that could potentially improve drug delivery by limiting drug loss during exhalation is currently not available on bilevel ventilators. The aim of this in vitro study was to compare aerosol delivery of amikacin with a vibrating mesh nebulizer coupled to a single-limb circuit bilevel ventilator, using conventional continuous (Conti-Neb) and experimental inspiratory synchronized (Inspi-Neb) nebulization modes...

BACKGROUND: Nasal highflow (NHF) provides a warmed and humidified air stream up to 60 L/min. Recent data demonstrated a positive effect in patients with acute hypoxemic respiratory failure, especially when caused by pneumonia. Preliminary data show a decrease in hypercapnia in patients with COPD. Therefore, NHF should be evaluated as a new ventilatory support device. This study was conducted to assess the impact of different flow rates on ventilatory parameters in patients with COPD. MATERIALS AND METHODS: This interventional clinical study was performed with patients suffering from severe COPD...
