Non-invasive ventilation in COPD exacerbations Clinical

Look at the pH, PaCO 2, and B.E. / HCO 3 – to decide whether compensatory mechanisms are at work. Once the acid-base disorder is identified as respiratory or metabolic, we must look for the degree of compensation that may or may not be occurring. we know that the system not primarily responsible for the acid-base abnormality must assume the responsibility for returning the pH to the normal

If so, then they are a CO2 retainer, and it is this CO2 retention that serves as their respiratory drive. If the patient had COPD, I wouldn't feel comfortable applying a NRB at 15 L/min. If the patient had COPD, I would try and utilize a Venturi mask and titrate the FiO2 (fraction of inspired oxygen) to a percentage that maintained a decent O2 sat, but didn't wipe out the respiratory drive

ABG INTERPRETATION Steps to ABG interpretation Step 1: Determine the pH – If pH is < 7.40 – then an acidosis is present If pH is > 7.40 – then an alkalosis is present Step 2: Determine the cause of the Acidosis or Alkalosis by looking at the PCO2 and HCO3-If pH < 7.40 and the PCO2 is high – then it is a RESPIRATORY ACIDOSIS If pH < 7.40 and the PCO2 is low – then it is a METABOLIC
