Week 5 Flashcards
(30 cards)
What is the rigid tonsillar used for?
Used for suctioning mouth and throat (oro pharynx), especially for patients who can’t clear saliva, vomit, or secretions. Often used in post-operative or semicomatose patients.
Also known as ‘Tanker’.
What is open-sterile technique?
A sterile procedure that requires disconnecting the patient from the ventilator. Often reserved for patients who don’t need continuous ventilatory support. Sterility must be maintained.
Important for preventing infections.
What is closed-technique suctioning?
Involves a sterile closed system suction catheter. Used without disconnecting the patient from the ventilator. Commonly used in critically ill patients.
Helps maintain continuous ventilatory support.
What are the indications for suctioning a patient?
Presence of abnormal breath sounds, visible secretions, increased work of breathing (WOB), decreased saturation (SpO2).
Example of abnormal breath sounds includes coarse crackles.
How often do we suction a patient?
Never on a routine basis. Evaluate and perform suctioning only when necessary.
Routine suctioning can cause trauma and complications.
What are the suction pressure ranges for neonates?
-80 to -100 mm Hg
Important to use appropriate pressure to avoid trauma.
What are the suction pressure ranges for pediatrics?
-100 to -120 mm Hg
Adjustments based on patient size and condition are crucial.
What are the suction pressure ranges for adults?
-120 to -150 mm Hg
Suction pressure should be monitored closely to ensure patient safety.
What is the maximum diameter of the catheter in relation to the artificial airway in adults?
The diameter of the catheter should be less than 50% of the artificial airway in adults.
What is the maximum diameter of the catheter in relation to the artificial airway in neonates?
The diameter of the catheter should be less than 70% of the artificial airway in neonates.
What can happen if the catheter is too large?
It can obstruct the airway, causing atelectasis and hypoxemia.
If your patient is intubated with a size 7.0-mm, what size suction catheter would you use?
Multiply the inner diameter by 2 and then subtract by 2.
Example: 7x2=14 → 12 French
What is the maximum time you can suction a patient?
Never more than 15 seconds.
Should you suction while inserting the catheter?
No, it can cause trauma.
How can you minimize hypoxemia during suctioning?
Reoxygenate with 100% O2 before and after for 30-60 seconds to prevent hypoxemia.
What should you monitor for to prevent cardiac dysrhythmias during suctioning?
Monitor for bradycardia.
What should you do to monitor hypotension/hypertension post suction?
Use close monitoring of vitals, as it can be caused by hypoxial stress.
What can cause atelectasis during suctioning?
Atelectasis can be caused by large catheter size or excessive suction.
What technique should be used to avoid mucosal trauma?
Use proper pressure technique to avoid trauma.
What can trigger increased ICP?
Increased ICP can be triggered by suctioning
How can you minimize increased ICP during a procedure?
Minimize with aerosolized anesthetics 15 min prior to procedure.
When does ICP usually return to baseline?
Usually returns to baseline in 1 min.
What technique reduces the risk of bacterial colonization?
Sterile technique reduces the risk of infection.
What type of saline should be used?
Normal saline ONLY.
