COPD 005.1 Rationale

As COPD progresses, patients often become hypoxaemic. Many patients tolerate mild hypoxaemia well, but once the resting partial pressure of oxygen in arterial blood (PaO2) falls below 8 KPa patients begin to develop signs of right-sided HF (cor pulmonale), principally peripheral oedema. The prognosis is poor and if untreated the five year survival is less than 50 per cent.

In stable COPD, patients use oxygen therapy for long periods during the day and night. Long-term oxygen therapy can improve survival in patients with COPD who have severe hypoxaemia, where PaO2 is less than 8 KPa. It can also reduce the incidence of polycythaemia (that is, raised red cell count), reducing the progression of pulmonary hypertension and improving psychological wellbeing.

NICE clinical guideline CG101 recommends that patients with oxygen saturations of 92 per cent or lower when breathing air, be considered for oxygen therapy. Pulse oximetry (SpO2) provides an estimate of arterial oxygen saturation (SaO2) and is non-invasive.

Pulse oximetry allows practitioners to assess patientsí level of oxygen saturation to determine if whether referral for clinical assessment and long-term oxygen therapy is appropriate. Pulse oximetry is a valuable screening tool for identifying patients who are appropriate for referral for long-term oxygen therapy. A normal pulse oximetry reading (SpO2 greater than 92 per cent) can reliably identify patients who do not need referral. However, pulse oximetry cannot predict which patients with an abnormal reading (SpO2 of 92 per cent or lower) have sufficiently severe hypoxaemia to require long-term oxygen therapy, therefore these patients require further assessment.


COPD 005.2 Reporting and verification

See indicator wording for requirement criteria.

The Business Rules require that a record that pulse oximetry has been performed AND the resulting oxygen saturation value are recorded to meet the requirements for this indicator.
