Can manual hyperinflation maneuvers cause aspiration of oropharyngeal secretions in patients under mechanical ventilation?

Background And Objectives: To evaluate whether manual hyperinflation maneuvers can cause aspiration of oropharyngeal secretions in patients under mechanical ventilation.

Methods: Adult patients under mechanical ventilation in whom a dye was injected in the oropharyngeal cavity and had their tracheal secretion aspirated after 30 minutes (min) participated in this study. In the event of dye slid, the patient was eliminated.

[Theoretical training for nurses in cardiac arrest attendance].

to apply a theoretical qualification program for nurses in cardiopulmonary resuscitation and compare the theoretical knowledge group-A-control with group-B-experimental. This program comprised three stages: Stage-I, evaluation pre-theoretical qualification; Stages-II and III, evaluation of the recent (one week after stage-I) and later (three months after stage-I) qualification. The sample was composed of 21 nurses in Group-A and 38 in Group-B.
