Definition of positive pressure in US English:

positive pressure

noun

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

    • ‘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.’
    • ‘All these changes can be reversed by effective treatment using continuous positive pressure ventilation.’
    • ‘Successful use of the laryngeal mask for positive pressure ventilation in anaesthesia is based on the avoidance of gas leak.’
    • ‘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.’
    • ‘Other contributing factors include the effects of intermittent positive pressure ventilation, patent ductus arteriosus, and problems with pulmonary toilet.’
    • ‘Use nasal intermittent positive pressure ventilation to treat sleep-related upper airway obstruction and chronic respiratory insufficiency in patients with DMD.’
    • ‘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.’
    • ‘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.’
    • ‘With the widespread use of noninvasive positive pressure ventilation, a more accurate assessment of auditory impairment is worthwhile to investigate in future research trials.’
    • ‘The scoring system has been proved to allow bias in favour of continuous negative extrathoracic pressure ventilation over intermittent positive pressure ventilation.’
    • ‘Close attention should be given to maintaining or replacing intravascular volume, because hypotension commonly accompanies the initiation of positive pressure ventilation.’
    • ‘Acute respiratory failure may develop rapidly, requiring intubation and intermittent positive pressure ventilation.’
    • ‘He responded well to supportive therapy with noninvasive positive pressure ventilation and was discharged 72 hours later without further complications.’
    • ‘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.’
    • ‘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.’
    • ‘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.’
    • ‘When respiratory failure occurred despite NIV, invasive positive pressure ventilation via an endotrachcal tube was initiated.’
    • ‘Patients with compromised airways and respiratory failure will require immediate endotracheal intubation and positive pressure ventilation.’
    • ‘They progress to respiratory distress with diffuse rhonchi and signs of consolidation, often requiring positive pressure ventilatory support.’
    • ‘Complications of nasal intermittent positive pressure ventilation include eye irritation, conjunctivitis, skin ulceration, gastric distension, and emesis into a full face mask.’
