Summary
Brief summary (as posted)
Preliminary studies have shown that NPPV can avoid tracheal intubation in 40% to 60% patients who have severe exacerbation of COPD. Recently, large-scale comparative effectiveness research (CER) also found that compared with invasive ventilation, NPPV can reduce mortality rates. But there's no high-quality clinical studies which can confirm this. Therefore, investigators believe that NPPV can avoid intubation in patients with severe exacerbation of COPD in ICU with perfect monitoring conditions and reasonable human resource allocation, in order to reduce IMV-related complications and improve patients' outcomes.

- label
- Noninvasive ventilation
- description
- Noninvasive positive pressure ventilation is achieved by Philips Respironics V60/Vision ventilator. Choose bilevel positive airway pressure mode, and adjust the fraction of inspire oxygen(FiO2) or oxygen flow rate to maintain patient's oxygen saturation(SpO2) between 88% to 92%. Parameter adjustment and weaning of NPPV follow the protocols used before.
- label
- Invasive ventilation
- description
- Intubated immediately and connected to the ventilator. Parameter adjustment and weaning of IPPV follow the protocols used before.
- label
- High flow nasal cannula
- description
- High flow nasal cannula of different models (large, medium and small) are selected depending on the size and comfort of the patient's nostrils. Adjusting the oxygen flow rate (O2 Flow) maintains the patient's SpO2 88% to 92%. The flow was initially adjusted to 25 L/min and the flow was gradually adjusted to the patient's maximum tolerance. The inspiratory gas temperature (31 to 37 °C) was set to the patient's maximum tolerance level. If the patient's condition deteriorates and the tracheal intubation standard is met , the patient is recommended to undergo invasive ventilation treatment, but the choice of the final respiratory support method should be decided by the attending physician, patient and family.
