Non-invasive ventilation use in status asthmaticus: 16 years of experience in a tertiary intensive care.
To describe the use of non-invasive ventilation (NIV) in adults presenting with status asthmaticus to Middlemore Hospital Critical Care Complex (CCC, South Auckland, New Zealand) from 2000 to 2015. ⋯ The use of NIV appears to be safe and effective in patients with severe asthma, including selected patients with an altered level of consciousness. NIV was well tolerated with a low need for subsequent intubation.

Assessing mechanical ventilation asynchrony through iterative airway pressure reconstruction.
Respiratory mechanics estimation can be used to guide mechanical ventilation (MV) but is severely compromised when asynchronous breathing occurs. In addition, asynchrony during MV is often not monitored and little is known about the impact or magnitude of asynchronous breathing towards recovery. Thus, it is important to monitor and quantify asynchronous breathing over every breath in an automated fashion, enabling the ability to overcome the limitations of model-based respiratory mechanics estimation during asynchronous breathing ventilation. ⋯ The iterative pressure reconstruction method is capable of identifying asynchronous breaths and improving respiratory mechanics estimation consistency compared to conventional model-based methods. It provides an opportunity to automate real-time quantification of asynchronous breathing frequency and magnitude that was previously limited to invasively method only.

The American Academy of Pediatrics Section on Transport recommends the use of portable ventilators during the transport of patients with advanced airways. We sought to identify knowledge gaps and evaluate the effectiveness of a transport ventilator competency boot camp. ⋯ Quality data were useful in identifying areas requiring knowledge and competency assessment. Re-assessment results validated the need to conduct education and competency assessment at defined intervals.

Risk factors for prolonged mechanical ventilation in patients with severe multiple injuries and blunt chest trauma: a single center retrospective case-control study.
Blunt chest trauma is common and is associated with morbidity and mortality in patients with multiple injuries, frequently requiring invasive mechanical ventilation. The aim of this study was to elucidate risk factors for prolonged mechanical ventilation (PMV). ⋯ Severe GCS (≤8), flail chest, or TTSS may be independent risk factors. Combining the three risk factors could provide high predictive performance for PMV.

Lack of Benefit of Heliox During Mechanical Ventilation of Subjects With Severe Air-Flow Obstruction.
The value of heliox (helium-oxygen mixture) for patients with severe air-flow obstruction is uncertain. The purpose of this study was to determine whether heliox could reduce the degree of hyperinflation and hypercapnia in mechanically ventilated patients with severe air-flow obstruction. ⋯ In mechanically ventilated subjects with severe air-flow obstruction, administration of heliox had no effect on indices of dynamic hyperinflation (plateau pressure and total PEEP) and resulted in only a small reduction in PaCO2 .
