Hypoxemia in Eisenmenger syndrome (ES) is a common feature of the disease. Improvement in PaO2 of severely obese patients with hypoxemia through a deep breath maneuver (DBM) and improvement on the V/Q match has been described previously.Objetive: To assess the impact of DBM on gas exchange (GE) on patients with both, ES and obesity.
30 patients with ES with obesity and obesity without ES, both with a body mass index (BMI) major than 35 were included. GE was evaluated with ABG sampling at room air and 100% oxygen fraction. They went through routine evaluation including echocardiography and pulmonary function test. Values were expressed as mean ± SD. Independent student t test were used to compare groups. p<0.05 was considered as statistically significative.
30 patients were included in two groups: 1) ES + obesity and 2) Obesity; Demographics variables as age, weight and height were: 55 ± 617; 11 years old, 87 ± 17 kgs, and 153.1 ± 9.5 respectively. The gas exchange values in the groups were:.
No changes were observed on GE with DBM in ES with obesity patients.
DBM in severely obese patients is useful to evaluate GE, but en ES with obesity patients, the DBM has important limitations.
