We observed that, compared to modes with spontaneous breathing activity, PCV induced damage to the diaphragm.
Multinomial logistic regression, using a stepwise approach, was then performed with the entire cohort for mode of delivery, with spontaneous vaginal delivery (SVD) acting as the reference category.
The mean age of the study group was 73 ± 10 years; 11 of them were female and mean APACHE II score was 19 ± 6. RSBI did not differ significantly between spontaneous mode and other combinations, but the best correlation with spontaneous mode was found with PS 5 PEEP:0 (P = 0.0001, r = 0.719), and the worst with PS 0 PEEP:5 combination.
Six mixed-breed female Landrace/Large White piglets (17 to 20 kg) were medicated with midazolam (Dormire; Cristália, São Paulo, Brazil) and subsequently intubated and connected to a mechanical ventilator in the supine position in spontaneous mode with a PEEP of 5 cmH2O and an inspiratory oxygen fraction (FiO2) of 1.0.
When children were able to trigger spontaneous breathing, they were changed to a pressure-support spontaneous ventilation mode with continuous positive airway pressure of 5 cm H2O.
Patients were ventilated in assist-controlled mode with repeated sequences of assisted spontaneous breathing under physiotherapist supervision.
The risk for TV to be greater than 6 ml/kg IBW was significantly increased with spontaneous breaths assisted by PSV modes (for PSV OR 19.36; [12.37–30.65]) and significantly reduced in APRV (OR 0.44; [0.26–0.72]) and PSV with guaranteed volume mode.
Women who planned a vaginal birth included all other women with spontaneous, augmented or induced labour, regardless of eventual mode of delivery.
Side mode and spontaneous emission background suppression is achieved with an intracavity etalon.
To avoid changes in alveolar ventilation, patients were ventilated in volume control mode and spontaneous respiratory movements were temporally suppressed with a neuromuscular blockade agent (0.1 mg/kg vecuronium bromide) if detected in airway pressure trace in the respiratory monitor.
