LITERATURE REVIEW 3 Literature Review Purpose The purpose of this literature review is to determine if meticulous oral care with  Chlorhexadine will help to reduce the incidence of ventilator acquired pneumonia (VAP) among  critically ill, mechanically ventilated adult patients in the intensive care unit (ICU) versus other  modalities.  A brief overview of the respiratory system and the pathophysiology of VAP will be  discussed.  This discussion will include results from previous research studies, predisposing  factors, disease etiology of VAP, signs and/or symptoms, diagnosis and treatments as well as  limitations and/or gaps in the research in order to help clarify this forever growing concern. Brief Overview Air enters the lungs through the nose where hair in the nose helps to filter the large air  pollutants before entering the trachea and bronchi in the lungs.  Sometimes air enters the mouth  which travels down the trachea and into the bronchioles where tiny hair-like cells called cilia line the walls.  This cilia traps pollutants with mucus and the body is able to cough it up (CDC,  2004).   Predisposing Factors When a patient requires to be mechanically ventilated, a plastic tube is inserted usually  through the oral cavity through the vocal cords and into the trachea; this tube impedes the body’s natural ability to cough up pollutants that may have entered through the mouth, thus contributing  to the risk factors for developing VAP (Yarham & Young, 2008).  The placement of this tube,  otherwise known as an endotracheal tube (ETT) will now allow the patient to be oxygenated via  the ventilator.  The lungs are a sterile environment and with the placement of the ETT allows for

LITERATURE REVIEW 4 harmful bacteria to enter via micro-aspiration from the accumulation of subglottic secretions that pool at the cuff site of the ETT. The cuff is a small balloon type anchor to hold the ETT in place  which is approximately 10-12 inches long and .05 centimeters in diameter. This micro-aspiration also increases the patient’s risk for developing VAP.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
