where does the Mcintosh go between epiglottis and base of tongue
where does the miller go under epiglottis and manually lift
if placement takes longer then 30 seconds what's the next step take out and oxygenate patient again before trying again
how do you confirm an ET tube placement 1. ascultate bilateral breath sounds 2. make sure no air at apigastrum 3. look at depth in cm on tube 4. if available use CO2 detector 5. x-ray to verify

when is a nasal ET tube used non emergency situations
when are magill forceps used during nasal ET intibation
what is sprayed in nasal passage before ET tube 1. vasoconstrictor to reduce bleeding 2. Lidocaine -anesthesic
what are the 2 methods for inserting a nasal ET 1. blind- breathing pt 2. direct visual- with laryngoscope/ magill forceps
what are the advantages of nasal ET 1. easier stabalization 2. more tolerated-less gagging/secretion/head movement 3. easier suction 4. less likely for pt to extibate self

what are the 3 alternative airways 1. LMA -Laryngeal mask airway 2. Combitube 3. EOA- Esophogeal obturator airway
when do you use a LMA for short term only when nasal/oral not possible, common in anesthesia
what are the advantages of the LMA 1. not a lot of manipulation/ head positioning 2. available from neonate to adult
disadvantages for the LMA 1. expensive 2. hard to get correct size 3. doesn't prevent aspiration
why does the LMA have to be checked constantly for aspiration/ vomit
what should be done ever time an artificial airway is placed in a pt check for bilateral breath sounds before securing
can a ET tube be placed through the LMA yes is can to secure a secure airway
2 main limitations to the LMA 1. cannot be used on even a semiconscous pt=gag 2. ventilation over 20 cm H2O= gastric destinsion
what is a combitube a double lumen device- can ventilate just one lung or both
can a combitube be inserted blindly yes, when intibation failed or with difficult airways
what is the advantage that the combitube has over other ET tubes if inserted into the esophogus the combitube has 2 cuffs and 2 airway passages. if the distal one ends up in the esophagus then the cuff will keep vomit out of airway and the resuscitator can be moved to the other airway and then ventilate the patient through those holes.
combitube is used in what situation blind intibation
what is very important to monitor when testing combitube placement 1. gastric sounds 2. bilateral breath sounds
who should the combitube not be used on 1. pediatric 2. very short adults
what are the advantages to the combitube 1. can do a blind intibation 2. can be rapidly inserted 3. pharyngeal cuff is well anchored to hard palate
what are the disadvantages to the combitube 1. placement of an ET tube is difficult with a combitube in place already 2. can't be used on pt with gag reflex
what is a double lumen ET tube 1. 2 different lumina- different lengths 2. one goes in either left or right bronchi 3. shorter one ends above carina 4. can ventilate each lung separtly 5. 2 cuffs
what are the differences in the double lumen ET tube 1. one has high volume low pressure cuff 2. one is a high pressure low volume cuff
what is unique about the 2 cuffs on the double lumen ET tube they have a radiopaque line on the cuffs as well as ET tube
why do the double lumins 2 cuffs have a radiopaque line to make sure the placesment of each is in the proper place to keep only one lung ventilated at a time
when is a double lumen Et tube used 1. after lung transplant- lung compliance different 2. when pt has a one sided lung problem 3. during lobe ectomy to ventilate one lung and not the other 4. protect good lung when one is have massive hemoptysis
what is a EOA an esophogeal obturator airway
when is a EOA used during emergency situations for unconscious pt and apneic
is a EOA a true ariway no
what is the principle behind EOA 1. stop airt from getting into stomach 2. esophagus is sealed with cuff- gas only in lungs 3. prevent aspiration
what is a the approx. length of the EOA 37 cm
differences betweet EOA to an ET tube 1. closed off distal end 2.supposed to go into esophagus 3. cuff blocks off esophgus 4. holes at pharyngeal level- not vented through one hole
EOA placement directions 1. check cuff 2. deflate 3. lock in mask 4. place head in neutral position 5.grasp jaw/ lift jaw 6. insert on right side till mask is seated 7. seal mask 8. ventilate- bilateral chest movement/ breath sounds only 9. inflate cuff
when should a EOA be removed 1. pt regain consciousness 2. pt breaths spontainous 3. ET tube is available
be prepared for what when removing EOA the pt will vomit get suction/ turn head/ have vomitus bag/ then deflaite cuff
before you take out the EOA what needs to be done about the pt airway make sure they have a nasal tracheal or ET tube before removing EOA
what are the EOA hazards 1. hole in esophagus 2. tracheal intibation- no ventilation 3. vomit upon removal
what should be done if an EOA is placed in a trachea remove! emergency! no ventilation
what are some EOa contraindications 1. semi conscious pt 2. kids under 16 3. coma easily reversed 4. need longer then 2 hrs 5. pt with esophageal trauma
how long can an EOA be in a pt 2 hrs
can kids under 16 use an EOA no, only made for adults
what are the parts of the mouth to mask 1. mouthpiece 2. one way valve 3. O2 outlet 4. 15/22 mm adapter 5. adequate seal
what are the types of self inflaiting bags 1. ohio hope 2 2. ambu (air mask bag unit) 3. air viva 4. stat blue
when are flow inflating bags used in anasthesia
who can use the oxygen powered resuscitator adults only
how does a oxygen powered resuscitator work 1. 50psi O2 source 2. demand valve delivering 100% O2
what are the steps to use bag resuscitator 1. stand behind pt 2. put mask on pt 3. hold bridge of nose with thumb 4. hold mask with index fingers 5. grab jaws with rest of fingers 6. can also be attatched to ET tube
what does a bag resuscitator do gives pt IPPB at various oressures
is the FIO2 the same witha mask resuscitator no it is variable with the 1. flow rate 2. reservior 3. RR/ refill rate
when do you need to bag a pt 1. CPR 2. Resp arrest 3. deteriorating pt 4. pre/post oxygenating during suctioning artificial airway 5. transporting pt
what are some hazards and complications for bagging a pt 1. failure to establish airway- in esophagus/ bronchi 2. cervical/spinal trauma- chin lift not hyperextended 3. gastric iinsufflation 4. barotrauma 5. vomit/ aspiration
how do you correct gastric insufflation 1. 2 sec to deliver volume= less problem 2. use cricoid pressure = less problem
how can you prevent a barotrauma in bagged pt 1. use correct size bag 2. use pressure relief valve @ 35-40 cm H2O
how can you prevent vomiting in bagged pt 1. turn patient and compress stomach before 2. in tibate after compressing stomach 3. put in nasogastric tube
