3. POSITION CHANGE AS A NURSING MANEUVER

5. Body positioning is one of the general kinds of nursing actions during care of patients. Body positioning is one of the general kinds of nursing actions during care of patients. Critically ill patients positioning maximizes ventilation to improve oxygenation which in turn would affect the individual’s ability to maintain an internal environment that allows normal cellular function The critical care nurse plays a crucial role in the assessment, diagnosis, and management of patients with respiratory problems who develop hypoxemia.

6. Studies related to the adequate duration in each position and the frequency of turning patients for maimizing ventilation to improve systemic oxygenation has not been attempted The importance of the effect of body position on ventilatory function and gas exchange has been appreciated Less information is available concerning the effect of position change on gas exchange in human body

8. To determine the effect of position change on oxygenation and respiratory mechanics in mechanically ventilated patients To determine the effect of position change on oxygenation and respiratory mechanics in mechanically ventilated patients

10. MATERIAL Setting Critical care units of the Main University Hospital in Alexandria.

11. Subjects Adult patients with respiratory problems receiving mechanical ventilatory support were studied. They were aged from 16 to 70 years. Adult patients with respiratory problems receiving mechanical ventilatory support were studied. They were aged from 16 to 70 years. Intern nurses were trained to help the researcher in turning patients, four at a time Intern nurses were trained to help the researcher in turning patients, four at a time 30 48

12. Patients were classified to four groups Normal lungs Bilateral lung disease Right lung disease left lung disease

13. Patients excluded from the study Low Lowhemoglobin Arrhythmi a Facial surgery Skeletaldeformity Head or spine injury obesity Abdominal distension distension Carbon monoxide poisoning, pulmonary hemorrhage, pulmonary hemorrhage, pulmonary abscess. hyperthermia

14. METHODS *HD, ABG, RM were evaluated immediately before and every half- hour after turning patient for a total of 6 hours for each patient *Patients were turned to left, prone, right, supine position respectively * Researcher trained nurses to help in patient turning * Instructions were given about how to turn the ventilated patients in the proper way Nurses’ instructions Patients positioning

20. Position change and respiratory mechanics B.L.P=Base line positionL..L.P= Left lateral position P.P= Prone positionR.L.P= Right lateral position S.P= Supine position

21. Position change and arterial blood gases B.L.P=base line positionL.L.P=Left lateral position P.P=Prone position R.L.P=Right lateral position S.P=Supine position

23. position changes had a significant effect on oxygenation in mechanically ventilated patients

24. The improvement in arterial blood gases depends on site and extent of lung pathology Normal lungs lungs Bilateral disease disease Unilateraldisease ABG are improved in all positions The best position is prone The subsequent are right and then left The subsequent are right and then left The same improvement in duration and frequency but less than in normal lung Are improved with the good lung down Are improved with the good lung down Are worsened with the affected lung down Are worsened with the affected lung down

25. In both Healthy lungs Diseased lungs Prone and side lying positions enhance the efficiency of O 2 transport and thereby minimize or avoid use of high concentration of supplemental oxygen and positive end expiratory pressure.

27. body positioning is a 24-hours concern For any critically ill patient

28. Patients with normal lungs and patients with bilateral lung disease Tur n Left 1.5 hr Prone 1.5 hr Right 1.5 hr Supine 1.5 hr

29. Patients with right lung disease Turn Left 1.5 hr Prone 1.5 hr Right 0.5hr Supine 1.5 hr

30. patients with left lung disease Tur n Prone 1.5 hr Right 1.5 hr Supine 1.5 hr No left

31. Position change is asimple way to reduce shunting and improve oxygenation Position change is a simple way to reduce shunting and improve oxygenation It allows reduction in FIO 2 and PEEP and reducing their complications *do your patients a good turn *Try the position changes early in the course of illness Turning a critically ill patients is not difficult. It requires four trained nurses

32. More studies are needed to evaluate Using larger sample Frequentcycles using different duration Steep position Other range of positions
