Acute effects of ventilator hyperinflation with increased inspiratory time on respiratory mechanics: randomized crossover clinical trial

Comparison of the effects of voluntary and involuntary breath stacking techniques on respiratory mechanics and lung function patterns in tracheostomized patients: a randomized crossover clinical trial

“…Measurements were considered acceptable if we detected no deflections in the flow or pressure curves and no plateau during the inspiratory pause, because such changes would suggest patient interference and the presence of leaks, respectively. 9 - 12 …”

Ventilator versus manual hyperinflation in adults receiving mechanical ventilation: A systematic review

“…We included nine studies that compared manual hyperinflation with usual care, two randomized crossover trial (Choi & Jones, 2005; Hodgson et al., 2000) and seven randomized controlled trial (Barker & Adams, 2002; Blattner et al., 2008; Maa et al., 2005; Malekzadeh et al., 2016; Patman et al., 2000, 2009; Paulus et al., 2011; Table 1). There were four studies comparing hyperinflation performed using the mechanical ventilator with usual care, three randomized crossover trial (Assmann et al., 2016; Chicayban, 2019; Lemes et al., 2009) and one randomized controlled trial (Naue et al., 2019; Table 2). Four more studies that compared that compared manual hyperinflation with that performed using the mechanical ventilator, with three randomized crossover trials (Berney & Denehy, 2002; Dennis et al., 2012; Savian et al., 2006) and one randomized controlled trial (Ahmed et al., 2010; Table 3).…”

“…According to the PEDro scale, 10 studies were classified as of high methodological quality (Assmann et al., 2016; Blattner et al., 2008; Chicayban, 2019; Choi & Jones, 2005; Hodgson et al., 2000; Lemes et al., 2009; Naue et al., 2019; Patman et al., 2000, 2009; Paulus et al., 2011) and seven of moderate quality (Ahmed et al., 2010; Barker & Adams, 2002; Berney & Denehy, 2002; Dennis et al., 2012; Maa et al., 2005; Malekzadeh et al., 2016; Savian et al., 2006). As noted, most of the selected studies were classified as of high methodological quality (PEDro scale > 5 points).…”

“…It is noteworthy that in the study by Naue et al (2019) the VHI maneuver associated with vibrocompression increased the volume of aspirated secretion. All studies used for this comparison found improvement on lung compliance, with three in static (Chicayban, 2019;Lemes et al, 2009;Naue et al, 2019) and one in dynamics (Assmann et al, 2016).…”
