Document Summary
Continuous petco2 monitoring can be used to assess the patency of the airway and the presence of breathing. Gradual changes in petco2 values may accompany an increase in co2 production (e. g. , sepsis) or decrease in co2 production (e. g. , hypothermia). Maintaining tube patency: the patient should be assessed routinely to determine a need for suctioning, but the patient should not be suctioned routinely. With the cst, oxygenation and ventilation are maintained during suctioning and exposure to secretions is reduced. Assess patient before, during, and after the suctioning procedure. If the patient does not tolerate suctioning (e. g. , decreased spo2, development of dysrhythmias), stop procedure and manually hyperventilate patient with. 100% oxygen or if performing cst, hyperoxygenate until equilibration occurs. Hypoxemia is prevented by hyperoxygenating the patient before and after each suctioning pass and limiting each suctioning pass to 10 seconds or less. If svo2/scvo2 and/or spo2 are used, trends should be assessed throughout the suctioning procedure.
