What are the contraindications for a Head tilt chin lift?
-Fractured neck
-Suspician of a neck fracture
What are the indications for oropharyngeal airways?
-Unconscious pt
support base of tongue
bite block (w/ET tube or seizures)
facilitate oral suctioning
What are the indications for nasopharyngeal airways?
Conscious pt
support base of tongue
facilitate nasal suctioning
use to decrease trauma during nasotracheal suctioning
What are some complications with nasopharyngeal airways?
trauma to mucosa (most common)
epistaxis
increased airway resistance
What are the signs for mild airways obstruction?
good air exchange
responsive and can cough forcefully
may wheeze between coughs
What is the treatment for mild airway obstruction?
-As long as there is good airway exchange, encourage victim to continue coughing and breathing
-Do not interefere with victim when they try to expel the foreign body
,-stay and monitor victim
-call 911 if mild obstruction continues
What are the signs of a severe airway obstruction?
Poor or no air exchange
Increased respiratory difficulty
Clutching neck with hands in a choking position
Unable to speak or cry
What is the treatment for severe airway obstruction in RESPONSIVE adult pt?
Perform abdominal thrusts
What is the treatment for severe airway obstruction in UNRESPONSIVE adult pt?
Start CPR, no pulse check
Before attempting to ventilate look for foreign object in mouth and remove it
Whats the purpose of the reservoir on a self inflating resus bag?
To provide 95-100% of oxygen at 15L/min
Using excessively high flows during manual resuscitation can cause what type of problem?
May cause the valves to jam
While manually ventilating a pt via ET tube the RT notices that it is getting more difficult to
compress the resus bag, What could be the cause of this problem?
Pt valve may be stuck open or closed
What are 2 limitations of pneumatic resus devices?
-Inability to detect changes in pts lung compliance and resistance
-High risk of gastric insufflation
What are 5 indications for oral and nasal intubation?
Provide a patent airway
Access for suctioning
means for mechanical ventilation
Protect the airway
Direct instillation of medication if IV unavailable
What are the 4 drugs that we can administer through the tubes when IV access is not available ?
, Valium/Versed
Atropine
Narcan
Epinephrine
How do you determine the dosage of administering drugs through the endotracheal tube?
Double the normal IV dose
What is the main indication for tracheostomy?
When pt requires long term ventilation
How should the RT respond to by-passing normal humidification mechanisms?
Provide adequate humidity
How should the RT respond to disruption of normal mucus clearance?
Suction PRN
What is the acceptable range of cuff inflation for an endotracheal tube?
20-25mmhg
What is the most serious complication of endotracheal intubation?
Laryngospasm
Right mainstem intubation would occur if the et tube is inserted past what mark at the lips?
25cm mark at the lips
how should the RT maintain airway patency?
By suctioning
What level of humidification should be maintained in order to prevent dehydration?
100% humidity at 37C
(best way to prevent obstruction)
What size laryngoscope blade is commonly used for adult pt?
Size 3
What size of laryngoscope blade is used for term infant?
Size 1
