Benefits of Manometer in Non-Invasive Ventilatory Support

Abstract

The study recommends for ventilatory support the use of a manual resuscitator equipped with MS or AVs, due to the risk of reduction in coronary perfusion pressure and iatrogenic thoracic injury during hyperventilation found using manual resuscitator without manometer.

Quality of Ventilations during Infant Resuscitation: A Simulation Study Comparing Endotracheal Tube with Face Mask

“…This is an effective method to avoid excessive peak pressures provided an adequate chest rise of the baby is confirmed and, on the other hand, to detect partial or full airway obstruction in the event that high pressures are generated but a chest rise is not observed [ 1 ]. Previous studies have recommended its use when performing ventilations with a self-inflating bag, since at present its use is not common practice [ 25 , 26 ]. In any case, the rescuer must also monitor the elevation of the thorax during each insufflation (i.e., the only estimation of the insufflated volume that is available in most CPR scenarios) to ensure that the airway is clear.…”

“…The use of a mechanical pressure manometer would also be useful during FM ventilation, where the direct monitoring of the pressure can also help prevent gastric insufflation [ 25 ] and the risk of bronchial aspiration, especially in infants.…”
