Definition of positive pressure in English:

positive pressure


  • [mass noun] Air or gas pressure greater than that of the atmosphere, as used e.g. in the artificial ventilation of the lungs.

    • ‘The lungs of patients with neuromuscular disease can be ventilated noninvasively by intermittent positive pressure ventilation provided by volume-cycled ventilators or by pressure-cycled ventilators.’
    • ‘Twenty-six patients were maintained on standard treatment, and the other 26 patients received nocturnal nasal ventilation with bilevel positive pressure ventilation added to their treatment.’
    • ‘With the widespread use of noninvasive positive pressure ventilation, a more accurate assessment of auditory impairment is worthwhile to investigate in future research trials.’
    • ‘One reason it may be overlooked is that positive pressure ventilation masks the characteristic paradoxical diaphragm/abdominal wall movement and the pulmonary restriction, which would otherwise be obvious.’
    • ‘Other techniques, using a Foley catheter or Fogarty biliary balloon catheter, positive pressure ventilation or high frequency ventilation, and bronchoscopic removal will not be discussed here.’
    • ‘Patients with compromised airways and respiratory failure will require immediate endotracheal intubation and positive pressure ventilation.’
    • ‘Acute respiratory failure may develop rapidly, requiring intubation and intermittent positive pressure ventilation.’
    • ‘Other contributing factors include the effects of intermittent positive pressure ventilation, patent ductus arteriosus, and problems with pulmonary toilet.’
    • ‘Close attention should be given to maintaining or replacing intravascular volume, because hypotension commonly accompanies the initiation of positive pressure ventilation.’
    • ‘The scoring system has been proved to allow bias in favour of continuous negative extrathoracic pressure ventilation over intermittent positive pressure ventilation.’
    • ‘There may be substantial benefits to early extubation and institution of noninvasive positive pressure ventilation for patients who are alert, cooperative and ready to breathe without an artificial airway.’
    • ‘Successful use of the laryngeal mask for positive pressure ventilation in anaesthesia is based on the avoidance of gas leak.’
    • ‘When respiratory failure occurred despite NIV, invasive positive pressure ventilation via an endotrachcal tube was initiated.’
    • ‘Noninvasive positive pressure ventilation refers to delivery of ventilatory support using a mechanical ventilator connected to a mask or mouthpiece instead of an endotracheal tube.’
    • ‘The advantage of high frequency oscillatory ventilation as compared to either conventional positive pressure or jet ventilation is its ability to promote gas exchange while using tidal volumes that are less than dead space.’
    • ‘He responded well to supportive therapy with noninvasive positive pressure ventilation and was discharged 72 hours later without further complications.’
    • ‘All these changes can be reversed by effective treatment using continuous positive pressure ventilation.’
    • ‘Complications of nasal intermittent positive pressure ventilation include eye irritation, conjunctivitis, skin ulceration, gastric distension, and emesis into a full face mask.’
    • ‘Use nasal intermittent positive pressure ventilation to treat sleep-related upper airway obstruction and chronic respiratory insufficiency in patients with DMD.’
    • ‘They progress to respiratory distress with diffuse rhonchi and signs of consolidation, often requiring positive pressure ventilatory support.’
