suctioning duration, time interval between suctioning, suction flow/pressure, suction catheter OD verses tube ID, duration on oxygenation, number and volume of hyperinflations, concentration of O2, closed or open suction system, use of double lumen suction catheter can cause what?
Can occur mainly as a result of hpoxemia. Mechanical Stim. of airway, vagal stimulation, and patient agitation.
- may also occur, caused by hypoxemia
- Can occur secondary to cardiac arrhythmias that can cause a decrease in cardiac output
- It also can potentially be caused by severe coughing episodes that can decrease venous return
-Some hemodynamically unstable patients may experience decreased cardiac output and hypotension due to hyperinflation pre and post suctioning
- can occur secondary to removing air from the lungs as secretions are removed. This can add to the patients hypoxemia.
- Excessively negative pressure and a suction catheter that is too large for the ID of the airway, are considered the main cause of this problem
Trauma can occur to the turbinates, pharynx, larynx, nasal mucosa, tracheal mucosa, and bronchial mucosa depending on the type of suctioning, nasotracheal or tracheal tube.
Excessive trauma can cause pulmonary or mucosal hemorrhage or tracheitis
What are the potential causes of Mucosal trauma?
- Negative pressures used for suctioning
- Excessive force when inserting the catheter
- Design of the suction catheter
- Adherence of catheter to tracheal wall
- Suctioning in absence of secretions
How can Contamination/Infection complications occur?
primarily from transmission by workers' hands.

How can Cardiac Arrest and Death complications occur?
The exact mechanism is not known and it may vary depending on the patients' stability at the time of suctioning.
How do you potentially avoid or minimize the complications with hypoxemia/hypoxia during suctioning?
- Hyperoxygenate, use a closed system catheter, post oxygenation and hyperinflation, 15 seconds max suction time, use the correct size
How do you potentially avoid or minimize the complications with Mucosal Trauma during suctioning?
Limiting suction pressures may minimize damage. Lubrication of the catheter, suc only when pulling out and rotate slightly, check for indications and stop when nothing there
How do you potentially avoid or minimize the complications with Contamination/Infection during suctioning?
- Sterile (aseptic) technique and gentile advancement of the catheter, when suctioning, should help minimize the problems. Gloves must be worn on both hands to prevent direct contact transmission with infected tracheal secretions.
- Closed suction systems also minimize organism transfer.
- Caregivers should use the CDC�s guidelines for Standard Precautions

It is recommended that the external diameter of the catheter should never exceed ________ the internal diameter of the airway.
risk of developing adverse reactionsor worsening clinical conditions as the result of the procedure
1. Patient doesn�t need airway suctioning
2. Untrained personnel or improper equipment should not be used for airway suctioning on a patient
3. An unstable cardiovascular status, especially with severe hypotension can cause the patient to go into cardiac arrest

How do you assess whether tracheal suctioning was effective or not?
- 1. Pulmonary secretions are removed
- 2. Breath sounds are improved
- 3. Work of breathing decreases
- 4. Oxygen saturation or arterial blood gases improve
- 5. If peak inspiratory pressure and measured airway resistance decreased for a patient on a volume cycled ventilator, or an increased tidal volume for a patient on pressure-limited ventilation.
What is the procedure of suctioning for artificial airway?
- 1. Assess the patient for indications
- 2. Assemble and Check Equipment
- 3. Preoxygenate and Hyperinflate the patient
- 4. Insert the Catheter
- - Insert the catheter carefully, until it can go no further.
- - Then withdraw the catheter a few centimeters before applying suction.
- 5. Apply Suction/Clear Catheter
- - Apply suction while withdrawing the catheter using a rotating motion.
- - Keep total suction time less than 10 to 15 seconds.
- - After removing the catheter, clear it using the sterile basin and bulk water/saline while applying suction.

Crit Thinking 1.Identify at least three hazards and complications of suctioning that are unique to the nasotracheal route?
Epistaxis, laryngospasm.insertion of the catheter into the esophagus, vomiting
Crit Thinking 2.Contrast the dysrhythmias one would expect as a result of vagal stimulation during the suctioning procedure versus those that would result from hypoxemia.
- Vagal stimulation would result in bradycardia or cardiac arrest.
- Hypoxemia is more likely to cause tachycardia and ectopy, such as premature ventricular contractions.
Crit Thinking 3.Differentiate between mucus, sputum and phlegm.
- Mucus: viscous secretions containing mucin, white blood cells water and inorganic salts.
- Sputum: material coughed up from the lungs and expectorated through the mouth.
- Phlegm: thick mucus secreted by the goblet cells in the respiratory tract.
Crit Thinking 4.Is sputum normally considered a high risk fluid for the transmission of bloodborne pathogens?
No, not unless it contains blood. More of a hazard for airborne transmission.
Crit Thinking 5.What is the rationale for personal protective equipment use while performing suctioning?
Besides the fact that sputum is �yucky� and who wants it on themselves, there is always the possibility of bleeding during the procedure. Other pathogens, such as MRSA and VRE, can betransmitted via contact.
Crit Thinking 6.Given the following scenarios, identify all possible causes of the problem and offer at least two alternative solutions to correct each problem.
- A.You turn on an electrical suction machine and it does not work.
- Check to see if it is plugged in, and if not, do so.
- Double check to see if you turned it on, and if not, do so.
- Change outlets and see if another one works.
- Check cord for frays or tears and replace machine if needed.
- B.In the middle of suctioning a patient, the suction is lost.
- Discontinue suction, reoxygenate and ventilate.
- Check to see if the catheter is obstructed, if so, rinse or replace.
- Check all connections to make sure they are tight fitting.
- Check suction collection container. If it is full, a safety valve will turn it off automatically.If so, change the container.
- Check another suction outlet. The main suction compressor may have malfunctions.
- C.You cannot get suction from a wall suction regulator.
- Make sure the quick connect is secured.
- Check that the suction control is turned on.
- Check another outlet to see if it works or if the entire system has malfunctioned.
- D.While attempting to suction a patient with an endotracheal tube, you cannot advance the catheter more than 5 inches.
- The tube may be obstructed, kinked, or the patient may be biting down.
- Make sure the patient is not biting, or use a bite block.
- Make sure you can ventilate the patient.
- Rotate the catheter gently, attempt to lavage.
- Attempt gently to reposition the endotracheal tube slightly.
- E.After suctioning a patient, you hear a honking or high pitched sound coming from the endotracheal tube.
- The tube may be obstructed or has been accidentally dislodged. Ensure you can ventilate the patient, verify tube position, and attempt to pass a catheter. You may need to extubate and manually ventilate if all of these actions fail.
Crit Thinking 7.Calculate the maximum catheter sizes that can be used: Show your work!
- ID 4.0 mm trach tube: 8 Fr (1/2 4 = 2 x 3 = 6 +2)
- ID 6.0 mm ET tube: 10 Fr (1/2 6 = 3 x 3 = 9 +2)
- ID 7.5 mm ET tube: 12 Fr (1/2 7.5= 3.75 x 3 = 10.5 +2), no odd sizes available, round to the smaller size.
- ID 10 mm trach tube : 16 Fr (1/2 10 = 5 x 3 = 15 +2), no odd sizes available
Crit Thinking 8.A patient is suffering from hypoxemia and dysrhythmias andbronchospasm during suctioning. Identify what methods you used to assess the patient's status during suctioning and describe what precautions should be taken to prevent each of the hazards mentioned.
- Patient assessment should include observation of color and comfort level, ECG monitoring, pulse oximetry, and auscultation.
- Hypoxemia and dysrhythmias can be prevented by adequate preoxygenation and hyperinflation. Correct suction pressures and catheter size will reduce hypoxemia. Gentle suctioning will prevent dysrhythmias and bronchospasm from vagal stimulation. Bronchodilator therapy may also be indicated.
