ABSTRACT

Objective. To evaluate the rapid shallow breathing (RSB) as predictor of the outcome of weaning from mechanical ventilation (AMV) in patients with acute respiratory failure (ARF). Design. A case report series.
Setting. An ICU of a tertiary care hospital of Mexico.
Patients. Ten ARF patients due to neurological emergencies six, cardiovascular unstability two, ARDS/ALI two, pneumonia one, metabolic disorders one, complicated abdominal surgery one.
Interventions. None.
Measurements and main results. Respiratory rate (f), minute ventilation (VE), tidal volume (Vt), rapid shallow breathing (RSB = f/Vt) were measured with Wrigth respirometer (WR) and ventilator spirometer (VS). APACHE II Score was 15 points, AMV days 7 ± 3 (range-36 hours to 34 days) and weaning time 24 hours (range 8-72); RSB was 40 vs 50 breaths/L/min, Vt 570 vs 515 mL, VE 12 vs 12 L and f 21 vs 21 breaths/min with WR and VS, respectively.
Conclusion. BRS is a good method for succesful weaning in patients with acute respiratory failure.
