A recent study in BMJ Innovations investigates the risks associated with manual ventilation using a resuscitator bag. When mechanical ventilators are unavailable, manual ventilation becomes the primary option. However, performing manual ventilation effectively requires skill, and improper technique can lead to patient harm.
In their research, the University of Tennessee Health Science Center found that using a safety valve accessory, which limits inspiratory flow, could potentially reduce these risks. For the study, TSI’s 5300 series flow meter, paired with FLO-Sight software, was utilized to monitor tidal volume and peak pressures during both inhalation and exhalation. TSI’s 5000 Series flow meters were ideal for this research, given their precise bidirectional flow sensing, volume measurement, and ability to monitor ambient and differential pressure—essential features for assessing ventilation safety.
