Analysis on potential risk of critical patients due to the difference of airway peak pressure of invasive ventilator in pressure controlled ventilation mode / 中国医学装备

ABSTRACT

Objective:To reveal the difference of airway peak pressure of different brands and models invasive ventilator in our hospital through test and analysis, and reveal that the difference might bring potential threat to the critical patients.Methods: Using adult simulated lung with adjustable respiratory resistance and compliance as the load of invasive ventilator to measure airway peak pressure of invasive ventilator in constant pressure controlled ventilation mode. Results: The results showed that the measured ventilators surely have differences in airway peak pressure in constant pressure controlled ventilation mode.Conclusion: For severe patients, if we ignore the peak airway pressure difference between invasive ventilators, there may be a threat to the critical patients.
