Effect of oral high frequency ventilation by jet or oscillator on minute ventilation in normal subjects.

High - frequency Jet Ventilation

High-frequency jet ventilation (HFJV) describes a technique of mechanical respiratory support based on the delivery of gases under conditions of constant flow and low pressure. Among the benefits ascribed to HFJV are lessened interference with hemodynamic function and reduced danger of barofrauma. The theoretical and technical aspects of HFJV are discussed and the clinical experience with 39 pa...

Use of high-frequency jet ventilation in neonates with hypoxemia refractory to high-frequency oscillatory ventilation.

OBJECTIVE To describe the response to high-frequency jet ventilation in infants with hypoxemic respiratory failure unresponsive to high-frequency oscillatory ventilation. METHODS This was a retrospective analysis of chart records on demographics, ventilator settings, blood gas analysis and calculated oxygenation index prior to and during the first 7 days of high-frequency jet ventilation in t...

High frequency jet ventilation and aspirin poisoning.

ASPIRIN poisoning is responsible for over 200 deaths per annum in England and Wales. Forced alkaline diuresis is advocated to hasten renal elimination of the drug when plasma salicylate levels exceed 500 mg/l, whilst charcoal haemoperfusion is the treatment of choice when plasma salicylate levels exceed 900 mg/kg.' This severity of poisoning causes gross respiratory, metabolic and coagulation d...

High-frequency jet ventilation: a case report.

High frequency jet ventilation and gas trapping.

We have compared three types of high frequency jet ventilation (HFJV) with conventional positive pressure ventilation in patients recovering from elective coronary artery bypass surgery. Twelve patients were allocated randomly to receive HFJV at ventilatory frequencies of 60, 100, 150 and 200 bpm from a standard jet ventilator at either the proximal or distal airway (HFJV.p and HFJV.d), or from...
