To improve the effectiveness of tracheal suctioning, a nurse should:
A. Suction for 20-second intervals
B. Pass the catheter through to the carina
C. Suction during insertion of the catheter
D. Hyperinflate and/or hyperoxygenate before suctioning
D
D. Hyperinflation decreases the risk for atelectasis caused by negative pressure of suctioning Preoxygenation converts large proportion of resident lung gas to 100% oxygen to offset amount used in metabolic consumption while oxygenation is interrupted, as well as to offset volume lost during suction procedure.
A. Suctioning longer than 10 seconds can cause cardiopulmonary compromise, usually from hypoxemia or vagal overload.
B. If resistance is felt after insertion of catheter for maximum recommended distance, catheter has probably hit carina. Pull catheter back 1 to 2 cm before applying suction.
C. Application of suction pressure while introducing catheter into trachea increases risk of damage to mucosa and increases risk of hypoxia because of removal of entrained oxygen present in airways.
