High-Frequency Positive Pressure Ventilation
International Anesthesiology Clinics, 1983The prototype for high frequency ventilation is found in nature — the respiration of hummingbirds and insects is synchronous with the beat of their wings. In 1915 Henderson et al. (1) commented on the rapid, shallow breathing in dogs during heat polypnea: “There may easily be a gaseous exchange sufficient to support life even when tidal volume is ...

A study of intermittent positive pressure ventilation
Medical & Biological Engineering, 1970Using one degree of freedom RC lung model a respirator design criterion minimising the harmful effects of positive pressure ventilation, has been developed. To suppress the ill effects of long-term mechanical ventilation a mechanical dead space has been inserted in the breathing circuit.

Pediatric noninvasive positive pressure ventilation
Pediatric Critical Care Medicine, 2001OBJECTIVE: To review the clinical use of noninvasive positive pressure ventilation (NPPV) in both acute hypoxic and hypercarbic forms of pediatric respiratory failure, including its mechanism of action and implementation. DATA SOURCES: Studies were identified through a MEDLINE search using respiratory failure, pediatrics, noninvasive ventilation, and ...

Non-invasive Positive-Pressure Ventilation
2001NIPPV can be delivered nasally or by face mask, using either a conventional mechanical ventilator or a machine designed specifically for this purpose. NIPPV has two major modes of supplying ventilatory support, namely continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BiPAP).

Patient–Ventilator Interaction During Noninvasive Positive Pressure Ventilation
Respiratory Care Clinics of North America, 2005The interaction between the patient and the ventilator is complex,especially in a "semi-open" system as for noninvasive ventilation(NIV). Air leaks around the mask are likely to occur, and they affect patient-ventilator synchrony. Several variables may be responsible for the mismatch between the start of the neural output and that of ventilatory aid ...

Noninvasive Positive Pressure Ventilation in burns
Burns, 2002Acute respiratory failure is a common complication of the severely burn-injured patient. Endotracheal intubation and mechanical ventilation is associated with a high rate of complications. Noninvasive Positive Pressure Ventilation (NIPPV) has been shown to be as effective as conventional ventilation in improving gas exchange and is associated with ...

Indications for Noninvasive Positive Pressure Ventilation
International Anesthesiology Clinics, 2005Noninvasive positive pressure ventilation (NPPV) is not a new concept. Noninvasive intermittent positive pressure ventilation using a mouthpiece or facemask has been used since the early 1960s. With the recognition of NPPV’s advantages, NPPV has become increasingly popular over the last decade in caring for patients with acute respiratory failure (ARF).

Noninvasive Positive-Pressure Ventilation and Ventilator-Associated Pneumonia
Respiratory Care, 2005There is much interest in the use of noninvasive positive-pressure ventilation (NPPV) to prevent intubation and afford a survival benefit for patients. The risk of pneumonia in patients receiving NPPV has been reported in 12 studies. Compared to patients receiving invasive mechanical ventilation (4 studies), the pneumonia rate is lower with the use of ...

Physiology of positive-pressure ventilation
2016Abstract During positive pressure ventilation the lung volume is reduced because of loss of respiratory muscle tone. This promotes airway closure that occurs in dependent lung regions. Gas absorption behind the closed airway results sooner or later in atelectasis depending on the inspired oxygen concentration.
