NIV should be considered for use in patients with a persisting Acute Hypercapnic Respiratory Failures after a maximum of one hour of standard medical therapy.
- Complete the Ad-hoc form
- Increase pressures from Initial 12/5 cmH2O to 20/5cmH2O – as tolerated over 1st hour
However, ICU should be contacted early if the patient has one of the following:
- Asthma – Intubation the option of choice in Life threatening
- Pneumonia – NIV should only be considered as a bridge to intubation
- No pre-exisiting respiratory issue – NIV not likely helpful
- pH <7.25 (low threshold for ICU input)
- pCO2 >6.5kPa (low threshold for ICU input)
- Type 1 Respiratory Failure (low threshold for ICU input)
