High-Frequency Positive Pressure Ventilation

International Anesthesiology Clinics, 1983
The 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 ...

Pediatric noninvasive positive pressure ventilation

Pediatric Critical Care Medicine, 2001
OBJECTIVE: 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 ...

Patient–Ventilator Interaction During Noninvasive Positive Pressure Ventilation

Respiratory Care Clinics of North America, 2005
The 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 ...

Experimental studies of continuous positive-pressure ventilation and high-frequency positive-pressure ventilation

Resuscitation, 1981
The ventilatory pattern of a conventional respirator (SV-900) was compared with that produced by a prototype (system H) of a low-compressive ventilator system for pressure/flow-generated, time-cycled, volume-controlled ventilation. The experimental conditions in this study on 10 dogs were light pentobarbital anaesthesia and normoventilation, using ...

Synchronized Nasal Intermittent Positive Pressure Ventilation

Clinics in Perinatology, 2021
Avoiding MV is a critical goal in neonatal respiratory care. Different modes of noninvasive respiratory support beyond nasal CPAP, such as nasal intermittent positive pressure ventilation (NIPPV) and synchronized NIPPV (SNIPPV), may further reduce intubation rates.

Noninvasive Positive-Pressure Ventilation

Postgraduate medicine
Preview In most cases of acute respiratory failure, mechanical ventilation and endotracheal intubation are the preferred treatment. However, a noninvasive approach is proving valuable in selected patients and has some advantages over standard mechanical ventilation. How are patients selected for this therapy? What are its risks and benefits?

Non-invasive Positive-Pressure Ventilation

2001
NIPPV 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).

Noninvasive Positive-Pressure Ventilation

2012
Noninvasive positive-pressure ventilation (NIPPV) augments spontaneous ventilation using the tight-fitting nasal or oronasal mask without endotracheal intubation. This can be used in a large number of conditions if there is no contraindication. The application of NIPPV should not delay clinically indicated endotracheal intubation.

Intermittent positive pressure ventilation

1982
Intermittent postive pressure ventilation (IPPV) was invented at least 200 years ago, but it was not until the 1950s that prolonged IPPV was used to treat poliomyelitis1 , the acute respiratory failure of chronic lung disease2, and tetanus3. The commonest use of IPPV remains during anaesthesia, but the treatment is also applied to very varied diseases ...
