The document provides instructions for suctioning a patient with a tracheostomy tube, including maintaining sterile technique, assessing the need for suctioning, using appropriate suction settings and time limits, and reassessing the patient afterwards. Key steps include pre-oxygenating the patient, inserting and rotating the suction catheter at the appropriate depth, suctioning for no more than 5-15 seconds, and monitoring the patient's condition after the procedure. Normal saline may be instilled if needed to loosen thick secretions before repeating suctioning.
