LTOT should not be prescribed during an acute exacerbation and should be limited to patients with a SO ₂ of ?92% who are breathless and unable to manage without the use of oxygen .

Patients are assessed for LTOT using pulse oximetry and either arterial blood gas or capillary blood gas tests. During a period of clinical stability, patients should undergo two arterial blood gas measurements at least three weeks apart. Patients eligible for LTOT should be initiated on a flow rate of 1L/min, and titrated up in 1L/min increments after 20 minutes, until SO₂ > 90%. Arterial blood gases are then measured to confirm that a target PO₂ ?8kPa (60mmHg) at rest has been achieved . Oxygen may be discontinued if clinical improvement is made and the patient is stable.

Great britain MRC domiciliary outdoors demonstration studied 87 patients with chronic bronchitis and you may emphysema who had been hypoxaemic, mainly hypercapnic along with a previously reported bout of cor pulmonale

Family oxygen is experience official research having LTOT over time from balances with a minimum of 7 months using their history exacerbation otherwise discharge away from hospital. For the 2001, 3058% off customers was discharged from health however, don’t found new criteria for LTOT . It offers enhanced historically in a few portion but many people remain wrongly went on to your LTOT. In the event just a small number of patients try given LTOT, the full yearly price of the house clean air service inside England are nearly ?87m in 20142015. But not, a review of cures have faster this new yearly spend because of the 20%. Approximately in the event the all of the diligent acquired a take-upwards eight months blog post-discharge, ?10-20m will be conserved every year .

Diligent groups requiring LTOT

Patients with COPD often require LTOT, and the Nocturnal Oxygen Therapy Trial (NOTT) and UK Medicines Research Council (UK MRC) trials, which took place in the 1980s, showed that LTOT treatment in appropriate patients can improve survival rates by around 40%, irrespective of chronic hypercapnia and previous episodes of oedema or pulmonary hypertension . NOTT was the first randomised controlled trial of LTOT in patients with COPD and included 203 patients who were randomised to receive either continuous oxygen therapy or 12-hour nocturnal oxygen therapy. Results from this trial suggested that overall mortality in the nocturnal group was 1.94 times that in the continuous oxygen therapy group over an eight year follow-up. These patients were randomised to receive no oxygen or 15 hours of oxygen a day. Over a five year follow-up, 19 patients (45%) died in the treatment group and 30 patients in the control (no oxygen) group (66.7%). Subsequent studies have confirmed that patients with clinically stable COPD with chronic hypoxaemia have improved pulmonary haemodynamics and life expectancy when treated with LTOT for at least 15 hours per day . LTOT has also been shown to correct nocturnal SO₂, decrease sleep latency and improve sleep quality for patients with COPD who develop hypoxaemia .

Patients receiving oxygen for 24 hours a day are at risk of increased CO₂ levels; therefore the target SO₂ for patients with COPD should be 8892%. Target oxygen saturations for all other conditions should be 9498% .
