| Popis: | Study design: Cross-sectional study. Objective: To evaluate the influence of continuous and intermittent noninvasive mechanical ventilation (NIV) on cardiac autonomic modulation and cardiorespiratory parameters in healthy women. Methods: Twenty subjects performed two types of NIV: continuous through CPAP and intermittent through Müller Reanimator. Initially they remained at rest for 20 minutes in spontaneous breathing. Then volunteers were subjected to 20 minutes of NIV application with the selected technique and finally remained at rest for 20 minutes in spontaneous breathing. Cardiorespiratory parameters and heart rate variability (HRV) were measured in all these moments. Results: There were no significant differences when comparing the two techniques. Differences were observed in HRV and cardiorespiratory parameters when analyzed individually. Lower values of heart rate and respiratory rate were observed in continuous ventilation when compared to values during ventilation with spontaneous breathing (p |
