The study by Sun et al1 in this issue of RESPIRATORY CARE, comparing high-frequency oscillatory ventilation (HFOV) and conventional mechanical ventilation, merits close attention because it is one of few studies demonstrating clear benefit from HFOV, relative to conventional mechanical ventilation, in preterm infants. In the study, 336 preterm infants (gestational age 32 weeks, birth weight 1,5...

The provision of good IAQ in schools is important both for the health of students and in maximising educational achievement. It is, however, common for school classrooms to be significantly under-ventilated and this can lead to high levels of CO 2 and other pollutants. Natural ventilation offers the potential to improve IAQ within schools whilst at the same time reducing running and maintenance...

This work continues the search for viable intractability assumptions over infinite groups. In particular, we study the possibility of phrasing random self-reducibility properties for infinite groups in an analogous manner to the case of finite groups with the uniform distribution. As a first step, it is natural to look for distributions which are translation-invariant, i.e., the probability of ...

patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...

The COVID-19 pandemic has caused a severe global problem of ventilator shortage. Placing multiple patients on single (ventilator sharing) or dual patient ventilation been proposed and conducted to increase the cure efficiency for ventilated patients. However, ventilator-sharing method needs use same settings all patients, which cannot meet different Therefore, novel multivent system non-invasiv...

A second scenario: the hospital decides to buy a new set of respirators for the ICU. Introduction is done by the company and the staff gets a maybe one hour lesson how to use the new respirator. Within a specific ventilator system many different modes of operation may be available, and the model(s) most appropriate for use in a given situation may be subject, at least in part, to certain patien...

Epidemiologically, the use of a ventilator and the virulence of causative bacteria link VAP to the host and the duration of respiratory management. Risk factors include long-term respiratory management with a ventilator, re-intubation, administration of antibacterial agents before the onset of pneumonia, primary disease (burns, trauma, central nervous system diseases, respiratory diseases, and ...
