BTS guideline for oxygen use in adults in healthcare and emergency settings

COPD and other conditions causing fixed airflow obstruction (eg, bronchiectasis) May need lower range if acidotic or if known to be very sensitive to oxygen therapy. Ideally use 'alert cards' to guide therapy based on previous blood gas results. Increase Venturi mask flow by up to 50% if respiratory rate is above 30 breaths/min. Recommendations G1-G2 and section 8.12.1 Exacerbation of CF Admit to regional CF centre if possible, if not discuss with regional centre or manage according to protocol agreed with regional CF centre. Ideally use 'alert cards' to guide therapy. Increase Venturi mask flow by up to 50% if respiratory rate is above 30 breaths/ min. Recommendations G1, G3, G6 Neuromuscular disease, neurological condition and chest wall deformity May require ventilatory support. Recommendations G1, G4, G6 Risk of hypercapnic respiratory failure Morbid obesity Recommendations G1,G5, G6 CF, cystic fibrosis; COPD, chronic obstructive pulmonary disease; IMV, invasive mechanical ventilation; NIV, non-invasive ventilation; PCO 2 , arterial or arterialised carbon dioxide tension.
