Ventilator-associated pneumonia is a bacterial pneumonia that develops in patients receiving mechanical ventilator support through an artificial airway (endotracheal tube). In this article, a study and analysis to the side effects of using endotracheal tube during ventilation period have been conducted; the study goal is to select 1 type of photoelectric sensors and use it to design and implement an automatic subglottic suction to prevent ventilation-associated pneumonia by immediately suctioning the area above the inflated balloon and permits aspiration of secretion in the subglottic space. So, a testing of photo detectors become a major of concern; moreover, photoelectric sensor is an equipment used to discover variety of parameters such as distance, absence or presence of an object, and wet area by using a light transmitter, often infrared, and a photoelectric receiver.

In this article, a testing of photoelectric sensors to detect the wet area above the cuff will be done to achieve the goal of designing and implementing automatic subglottic suction.
