A Study of Arterial Oxygenation During Haemodialysis
During haemodialysis hypoxaemia is frequently observed. Its causes are still not completely clear but diffusion impairment, decreased ventilation, a disturbed respiratory exchange ratio and ventilation/perfusion inequalities have all been incriminated. Other factors to be considered are the type of dialyser (flat plate, hollow fibre, coiled dialyser), membrane characteristics, first use or re-use of the membranes, composition of dialyser fluid (acetate or bicarbonate) and ultrafiltration. These factors may produce leukopenia and/or hypoxaemia of different magnitude and significance during haemodialysis.
