In other acute situations patients may need a higher concentration of oxygen and a non-rebreathe mask or simple oxygen mask is often used. Flow rates of 1-4 litres per minute are used with nasal cannulas, equating to a concentration of approximately 24-40% oxygen.Flow rates of up to 6 litres can be given but this will often cause nasal dryness and can be uncomfortable for patients (British Thoracic Society, 2008).hey deliver oxygen in a variable manner; this means the amount of oxygen inspired depends on the patientâs breathing rate and pattern. For this reason they are not suitable for use in the acute phase of illness with patients who need controlled oxygen therapy.
