OBJECTIVES: In mechanically ventilated patients, humidifier devices are used to heat and moisturize the inspired gas. Heating and humidifying inspired gas may prevent complications associated with the respiratory mucosa dryness such as mucus plugging and endotracheal tube occlusion. Two devices have been commonly used to this, either heated humidifier or the heat moisture exchange filter. This study aimed to compare the effects of the heated humidifier and a model of heat moisture exchange filter on respiratory mechanics in mechanically ventilated neurological patients. METHODS: This was a randomized crossover trial, involving 31 neurological patients under mechanical ventilation randomly assigned to the humidification devices. Expired tidal volume, peak inspiratory flow, peak expiratory flow, static compliance, dynamic compliance and respiratory system resistance were evaluated. Statistical analysis used the Kolmogorov-Smirnov test and Student's t test for paired samples, in which P values < 0.05 were considered significant. RESULTS: The heat moisture exchanger filter decreased expired tidal volume, peak inspiratory flow, peak expiratory flow (p < 0.001) and dynamic compliance (p = 0.002), and increased respiratory system resistance (p < 0.001). CONCLUSION: In the studied population, the use of a heat moisture exchange filter model leaded to several changes on respiratory mechanics parameters.

OBJECTIVE: Mechanical ventilation is associated with retained airway secretions. Manually assisted cough contributes to the displacement of bronchial mucus, whereas positive end-expiratory pressure increases collateral ventilation and maintains airway patency. This study aimed to assess the effects of manually assisted cough, either alone or added to increased positive end-expiratory pressure and inspiratory time (optimized manually assisted cough), on the expiratory peak flow and respiratory system mechanics in mechanically ventilated patients. METHODS: In this controlled and randomized clinical trial, respiratory mechanics and expiratory peak flow were assessed in male and female patients undergoing either tracheal suctioning alone, manually assisted cough followed by tracheal suctioning or optimized manually assisted cough followed by tracheal suctioning. RESULTS: Thirty-five patients completed the trial. Respiratory system resistance was significantly reduced after optimized manually assisted cough (16.0 ± 3.6 versus 12.4 ± 3.1 cmH2O/L/s; p = 0.04). The expiratory peak flow during optimized manually assisted cough was significantly higher in comparison with the values observed during manually assisted cough (112.3 ± 15.6 versus 95.8 ± 18.3 Lpm; p < 0.05). Both values were significantly higher than the values observed in the group undergoing tracheal suctioning alone (52.0 ± 7.6 Lpm; p < 0.001). CONCLUSION: Optimized manually assisted cough increases the expiratory peak flow in comparison with manually assisted cough; in addition, this procedure reduces respiratory system resistance.

Complications from immobility in intensive care unit patients contribute to functional decline, increased healthcare costs, reduced quality of life and higher post-discharge mortality. Physical therapy focuses on promoting recovery and preserving function, and it may minimize the impact of these complications. A group of Brazilian Association of Intensive Care Medicine physical therapy experts developed this document that contains minimal physical therapy recommendations appropriate to the Brazilian real-world clinical situation. Prevention and treatment of atelectasis, procedures related to the removal of secretions and treatment of conditions related to physical deconditioning and functional decline are discussed. Equally important is the consideration that prescribing and executing activities, mobilizations and exercises are roles of the physical therapist, whose diagnosis should precede any intervention.
