Comparative Study Observational StudyDifferent spontaneous breathing trials in patients with atrial fibrillation.
Weaning from mechanical ventilation is one of the most important and challenging problems for most intensive care unit (ICU) patients. Spontaneous breathing trial (SBT) is the most common method used to evaluate patients' ability to breathe by themselves and plays an important role in decision making for weaning. The aim of our study was to investigate the effect of different methods of SBT in respiratory care unit (RCU) patients with atrial fibrillation (AF) on weaning outcome. ⋯ The use of PSV trial might be considered first instead of T-piece trial for SBT when AF patients were ready to wean.

Clinical impact of adaptive servoventilation compared to other ventilatory modes in patients with treatment-emergent sleep apnea, central sleep apnea and Cheyne-Stokes respiration.
Adaptive servoventilation is a recent ventilatory mode initially designed to treat Cheyne-Stokes respiration (CSR). Recently, the efficacy of ASV has been discussed for the treatment of central sleep apnea (CSA) and treatment-emergent central sleep apnea (treatment-emergent CSA) where other forms of traditional positive airway pressure (PAP) may be insufficient. ⋯ These data confirm that ASV is an efficient treatment in patients with treatment-emergent CSA, CSA/CSR significantly decreasing residual AHI. In both groups, compliance rate was high and sleepiness improved. It is relevant that the 2 patients who died of sudden death were treated with PAP.

Validation of a Portuguese version of the STOP-Bang questionnaire as a screening tool for obstructive sleep apnea: Analysis in a sleep clinic.
Screening methods have become increasingly important owing to the growing number of patients suspected of obstructive sleep apnea (OSA) being referred for sleep consultation. The STOP-Bang questionnaire has been validated as a screening tool for OSA in surgical patients. ⋯ The STOP-Bang questionnaire showed high sensitivity and PPV for OSA with the probability of severe OSA steadily increasing, the higher the scores. Furthermore, a low score showed high predictive value for the exclusion of moderate/severe OSA. The STOP-Bang questionnaire can be a powerful tool for stratifying patients in the diagnosis of OSA.

The value of cough peak flow measurements in the assessment of extubation or decannulation readiness.
Insufficient cough strength has a major role in extubation and decannulation outcomes. Cough capacity can be easily evaluated by measuring flows during coughing. ⋯ It is important to standardize these measurements and start using them routinely in the extubation and decannulation processes. Values of cough peak flow >160 L/min measured at the mouth or a value of cough PEF >60 L/min measured at the endotracheal tube suggest successful decannulation or extubation.
