Q

what are two common causes of lower airway obstruction?

A

Q

what are the guidelines for rescue breathing (5)

A 
give 12 to 20 breaths per minute
each breath over 1 second
each breath should have chest rise

use supplemental O2 as soon as it is possible
44
Q

Tachypnea, increased respiratory effort, grunting, crackles, diminished breath sounds, tachycardia, and hypoxemia are all signs of what?

A

Lung tissue disease

45
Q

In the case of lung tissue disease, what do pediatric patients demonstrate grunting?

A

partial closure of the glottis helps keep alveoli open

46
Q

Inadequate respiratory effort, “breathing funny”, that may be resulting from a host of conditions including neurologic disorders such as seizures, CNS infections, head injury, brain tumor, or hydrocephalus is referred to as what?

A

Disordered control of breathing

47
Q

this condition can range from causes that include swelling of the tonsils, adenoids, or other soft tissues to a foreign body lodged in the nose, pharynx, or larynx

A

Upper airway obstruction

48
Q

what should you consider before suctioning the airway of a child with an upper airway obstruction caused by edema from infection like croup, allergic reaction?

A

Suctioning may cause increased agitation and increased respiratory distress. Instead, consider allowing the child to assume a position of comfort with nebulized epinephrine

49
Q

A child with an obstruction caused by the tongue with a decreased level of consciousness may benefit from what?

A

an oral or nasal airway adjunct

50
Q

If a child has a swollen airway, what is a consideration when choosing an ET tube?

A

In order to prevent injury, use a smaller tube, up to half the size predicted for the childs age

51
Q

for a child that needs more than 40% O2 concentration, what should you consider using

A

Heliox, helium oxygen mixture

52
Q

what is the first line medication for a child with an obsttructed airway from croup. What is further added with severity?

A

dexamethasone for mild case, with increased severity also consider nebulized epinephrine and nothing by mouth

53
Q

for mild allergic reaction, what is the first line treatment?

A

oral dose of antihistamine

54
Q

for mild to moderate allergic reaction, what are the steps you should be prepared to take?

A

IM epinephrine q 10 to 15 minutes as needed
IV prednisone
treat wheezing with albuterol neb
anticipate ET tube

55
Q

for a child less than 1 year with a FBAO, what are the three steps you should take?

A
  1. confirm severe airway obstruction
  2. Give 5 back slaps and up to 5 chest thrusts
  3. Repeat step two until object is expelled or the child becomes unresponsive.
56
Q

for a child older than 1 year with FBAO, what are the three steps you should take?

A
  1. ask the child if he or she is choking
  2. stand or kneel behind the child and give Heimlich maneuver
  3. Repeat steps until the object is expelled or the patient becomes unresponsive.
57
Q

If a child with a FBAO becomes unresponsive, what do you do?

A

Begin CPR without pulse check
Check for FB every time you open the mouth and remove if you can see it. Do not do a blind finger sweep.
Continue CPR for 5 cycles or 2 minutes, if you are still alone leave the child to activate the emergency response system

allow position of comfort

specialty consultation
