The effect of non-invasive sequential ventilation treatment based on the use of an invasive ventilator on the arterial blood gas and inflammatory stress reaction in patients with severe pneumonia with respiratory failure

To investigate the impact of non-invasive sequential ventilation treatment based on the use of an invasive ventilator on the arterial blood gas and inflammatory stress reaction in patients with severe pneumonia with respiratory failure. Ninety patients with severe pneumonia and respiratory failure were equally separated into two groups via a random number table: a conventional treatment group (subjected to invasive mechanical ventilation) and a study group (subjected to invasive mechanical ventilation and non-invasive sequential ventilation treatment). We compared the two groups with respect to several key parameters before and after treatment, including mechanical ventilation time, invasive ventilation time, intensive care unit (ICU) stay, hospital stay, blood gas analysis indicators and the levels of inflammatory factors in the serum. We also compared the two groups with regards to complications. Mechanical ventilation time, invasive ventilation time, ICU stay and hospital stay in the study group were significantly shorter than that in the conventional treatment group (p < 0.05). Arterial Oxygen Saturation (SaO2), Partial Pressure of Oxygen (PaO2) and pH in the study group after intervention were significantly higher than those in the conventional treatment group after intervention (p < 0.05). Following intervention, white blood cell (WBC), serum c-reactive protein (CRP) and serum interleukin-6 (IL-6) were significantly lower than those in the conventional treatment group (p < 0.05). The total incidence of complications in the study group was markedly lower than in the conventional treatment group. Non-invasive sequential ventilation therapy based on an invasive ventilator had a significant treatment impact on patients with severe pneumonia and respiratory failure. This treatment effectively reduced the average treatment time, improved blood gas analysis indicators and reduced inflammatory stress, thus reducing the incidence of complications.
