What should the nurse do to improve the effectiveness of tracheal suctioning?

Question

Quizplus · Accepted Answer

Hyperoxygenation provides some protection from suction-induced decline in oxygenation.Hyperoxygenation is most effective in the presence of hyperinflation such as encouraging the patient to deep breathe or increasing ventilator tidal volume settings.
Suctioning longer than 10 seconds can cause cardiopulmonary compromise,usually from hypoxemia or vagal overload.If resistance is felt after insertion of the catheter for a maximum recommended distance,the catheter has probably hit the carina.Pull the catheter back 1 to 2 cm before applying suction.Application of suction pressure while the catheter is introduced into the trachea increases the risk for damage to the mucosa and increases the risk for hypoxia because entrained oxygen present in the airways is removed.
