Leukins invented the sputum trap |
Sputum specimen trap no suction until you occlude the thumb port, never suction on insertion.
|
|
Suctioning |
Selecting suction catheter size :External diameter(ED) of suction catheter should be no more than 1/2 internal diameter(ID) of artificial airway have to convert french to millimeters to ensure the the suction catheter :There are formula to estimate proper catheter to use when you suction When you have an ETT that is 8, that means the internal diameter ::ID of the ETT x 3/2 (then use the next larger Fr size ::ID x 2 (then use the next smallest Fr size Fr only comes in even numbers. or if you prefer use the ID x2. much easier so if the ID of the ETT is 8, then 8 x 2 = 16, next smallest size even is 14 |
|
Suctioning |
Vacuum Pressure :Adults should be -120 to -150 mmHg :children should be -100 to -120 mmHg :Infants -80 to -100 mmHg
|
|
Adult trachea |
Adult trachea :20 to 24 cm :7.75 to 9.5 inches |
|
Endotracheal suctioning |
Two techniques for endotracheal suctioning :Open, sterile technique requires disconnecting patient from ventilator :Closed technique uses sterile, closed in line suction catheter which is attached to ventilator circuit ::suction catheter can be advanced into patients endotracheal airways without patient ventilator disconnection
|
|
Endotracheal suctioning |
Step 1: assess patient for indications :Patient should never be suctioned according to preset schedule, they should be suctioned PRN :Abnormal breath sounds (e.g. coarse crackles or rhonchi) suggest that suctioning is needed
|
|
Endotracheal suctioning |
Step 2: assemble and check equipment Step 3: hyperoxygenate patient (give high FiO2 for a few breaths before suction procedure) :Use 100% oxygen Step 4: insert catheter Step 5: Apply suction/Clear catheter :Total suction time should be less than 15 seconds Step 6: reoxygenate patient |
|
Endotracheal suctioning |
Step 7: monitor patient and assess outcomes(breath sounds, Pulse via the pulse ox, SpO2, respiratory rate and tidal volumes, skin color, and consistency of sputum) Minimizing complications and adverse responses :Pre oxygenation helps minimize incidence of hypoxemia :Avoid atelectasis by limiting amount of negative pressure used and the time suctioning
|
|
Endotracheal suctioning |
Minimizing complications and adverse responses :Keeping duration of suctioning as short as possible :Using appropriate size suction catheter, and avoiding disconnection from ventilator :Use sterile technique during suctioning and manually ventilating patient to minimize bacterial colonization :Do not routinely instill sterile normal saline into artificial airway prior to suctioning unless necessary to help mobilize thick secretions |
|
Nasotracheal suctioning |
Indicated for patients who retain secretions but do not have artificial airway in place Placing catheter in larynx and trachea is facilitated by having patient assume "sniffing position" Procedure may cause patient to gag or regurgitate :Avoid suctioning immediately after meals (wait at least 30 minutes) :Prepare to reposition patient and suction oropharynx if this occurs(use yankaur suction)
|
|
procedures thath minimize complications of suctioning, include all of the following, except: |
Preoxygenation Limiting negative pressure Using septic technique Limiting suction time |
|
Sputum sampling |
Purpose: collect to identify organisms from the airway that affect the patient Patients with strong enough cough can provide ample sample sputum specimen by expectorating into a sterile cup Sterile technique must be maintained when touching connection points on sterile/Lukens trap
|
|
Pharyngeal airways |
We have two pharyngies, nasopharynx and the oropharynx. the soft rubberized plastic goes in the nasal pharynx, the hard plastic goes into the orophraynx |
|
Establishing an artificial airway |
Routes :Pharyngeal airways extends only into pharynx :Artificial airways placed through mouth and nose into trachea are called endotracheal tubes
Routes :Intubation: process of placing artificial airway into trachea ::orotracheal intubation is when tube is passed through mouth on its way into trachea ::nasotracheal intubation is when endotracheal tube is passed through nose first |
|
Pharyngeal airways |
Nasopharyngeal airway is most often placed to facilitate frequent nasotracheal suctioning Nasopharyngeal airways is the nasal trumpet :Minimize trauma to nasal mucosa caused by suction catheter :Used for repeated suction attempts |
|
Pharyngeal airways |
Oropharyngeal airways should be restricted to unconscious patient to avoid gagging and regurgitation Maintaining Patent airways is number 1 goal :Maintains patent airways by preventing tongue from obstructing oropharynx :can be used as a bite block for patients with oral tubes |
|
Pharyngeal airways |
:Nasopharyngeal airway ::also called nasal trumpet :Provides airway ::Also route for N/T suctioning |
|
Pharyngeal airways |
Oropharyngeal airways (very uncomfortable, so unconscious or semi conscious) :insert in mouth with tip pointing up :then rotate so tip rests against back of tongue :NOT tolerated in the conscious patient |
