Oxygen Supplementation and Ventilator Hyperinflation in the Endotracheal Suction (OSVHES)

Sponsor: Universidade Federal de Sao Carlos

Summary

This is a double crossover study where all patients are randomly allocated to one of two treatment sequences associated with endotracheal aspiration.The first treatment (A) uses two suctioning methods for each patient: one involving hyperoxygenation with administration of 100% oxygen 1 minute before and after suction (intervention I), and the other hyperoxygenation with oxygen supply to 20% above basal offer (Intervention II) in the same way.The second treatment (B) uses a technique of hyperinflation with the mechanical ventilator (PEEP-ZEEP) associated with hyperoxygenation. The intervention I, uses PEEP-ZEEP offering 20% above basal oxygenation and intervention II uses the PEEP-ZEEP with basal oxygen supply in the same way. All subjects were randomly allocated using sealed envelopes to a treatment sequence A or B on Day 1. Patients received two treatments, at least four hours apart. The first treatment is in the morning and the alternate treatment is performed in the afternoon. On Day 2 the order of the treatments was reversed using the same patient position sequence.The interventions I and II are performed at least 4 hours apart to minimize any carryover effect.
