Multicenter Study Observational Study
The use of a fully automated automatic adaptive servo ventilation algorithm in the acute and chronic treatment of central sleep apnea.
Central sleep apnea (CSA), in association with obstructive disordered breathing, occurs in patients using opioids long-term and those with congestive heart failure. In these patients, treatment with CPAP frequently fails. The current adaptive servoventilation (ASV) devices are promising for the treatment of complex sleep-disordered breathing. These devices use algorithms to automatically titrate expiratory and inspiratory pressures. We hypothesized that an ASV device operating automatically would significantly reduce the frequency of breathing events in patients with mixed sleep apnea during polysomnography and with 3 months of treatment. ⋯ The ASV device treated complex breathing disorders using automated algorithms. Compared with CPAP, patients reported improved sleep quality. Home use of ASV remained effective with acceptable adherence and improvements in daytime sleepiness.

Indwelling arterial catheters (IACs) are used extensively in the ICU for hemodynamic monitoring and for blood gas analysis. IAC use also poses potentially serious risks, including bloodstream infections and vascular complications. The purpose of this study was to assess whether IAC use was associated with mortality in patients who are mechanically ventilated and do not require vasopressor support. ⋯ In hemodynamically stable patients who are mechanically ventilated, the presence of an IAC is not associated with a difference in 28-day mortality. Validation in other datasets, as well as further analyses in other subgroups, is warranted.

Randomized Controlled Trial
Targeted Fluid Minimization Following initial Resuscitation in Septic Shock: A Pilot Study.
IV fluid represents a basic therapeutic intervention for septic shock. Unfortunately, the optimal administration of IV fluid to maximize patient outcomes and prevent complications is largely unknown. ⋯ This pilot study suggests that TFM in patients with septic shock can be performed using protocol-guided assessments of fluid responsiveness. Larger trials of TFM in septic shock are needed.
