Q

What are markers of respiratory distress/failure

A
  1. marked tachypnea and tachycardia
  2. stridor
  3. accessory respiratory muscles (during inhalation)
  4. inability to speak normally as a consequence of breathlessness
  5. agitation or lethargy as a consequence of hypoxemia
  6. depressed consciousness due to hypercapnia
  7. paradoxical abdominal wall movement
  8. the abdominal wall retracts inward with inspiration, indicating diaphragmatic fatigue (pushes out)

Q

what is the first sign of respiratory distress

A

acrocyanosis

because blood is diverted to vital organs

Q

what do you order for diganostic evaluation of dyspnea?

A

CBC
CMP
Peak expiratory flow rate
will help differentiate asthma/COPD from other disorders
decreased in obstructive disease
pt noncompliance due to acute dyspnea will affect the results
ABG
EKG
Troponin
BNP or N-terminal pro BNP
D-Dimer
CXR
Bedside Point of Care Ultrasound
helps differentiate acute cardiac from noncardiac causes
pleural effusion, pneumothorax, pulmonary consolidation, intravascular volume status, cardiac tamponade, cardiac function
CT scan, CTA, V-Q scan

Q

what is the INITIAL goal of dyspnea

A

admit to maintain O2 if hypoxemia

THEN see underlying cause

16
Q

Goal O2 for hypoxia in general and for COPD

A

not black and white

O2 > 90 is MC (chronic COPD may have a lower O2 - so do not treat them too much or they will lose their drive

17
Q

How do you supply O2

A

depends on how bad their O2 stat

Simple mask is most (6-10 L)
NC (0.25 - 4)

18
Q

What is the high flow O2

A

High flow NC can be used up to 40 L/min

19
Q

what is the non-rebreather bpm?

A

O2 builds up in bag and goes through a one-way valve so that they are not breathing in their expired air

need to make sure that there is not an obstruction

20
Q

If there is help of O2, what is next?

A

a little more invasive

CPAP or BiPAP

CPAP = same during inhilation and exhalation (sometimes have trouble exhaling)

BiPAP higher pressure while breathing in

21
Q

MC sign of an upper airway obstruction

A

stridor

22
Q

explain stridor

A

high-pitched inspiratory stridor

23
Q

What is the MCC of stridor in neonates

A

Laryngotracheomalacia

24
Q

What are the infectious etiologies of upper airway

A

Croup (laryngotracheobronchitis)
Bacterial tracheitis
Retropharyngeal abscess
Peritonsillar abscess
Epiglottitis

not on exam?

25
Q

MC age and object for airway obstruction in a child

A

1-3 years
food and toys

26
Q

MC foods that lead to FB obstruction in child

A

peanuts, sunflower seeds, RAW carrots, raisins, grapes, and hot dogs

they cannot be chewed up enough

27
Q

Presentation of airway FB obstruction

A

sudden coughing/choking associated with gagging, stridor or cyanosis

28
Q

presentation of laryngotracheal FB

A

STRIDOR, hoarseness or complete apnea

PA and lateral soft tissue neck

29
Q

presentation of Bronchial FB and what you order

A

unilateral wheezing and decreased breath sounds

PA and lateral CXR
inspiratory and expiratory

30
Q

confirms or rules out diagnosis
therapeutic to remove FB

A

Bronchoscopy

31
Q

what does inspiratory and expiratory FB

A

inspiratory normal
expiration = lung will not collapse, get larger, and eventually pneumothroax

32
Q

what is atelectasis

A

alveoli do not open and do not enter sacs, so tissue looks lighter gray or white (because air is black)

33
Q

if a FB is stuck for a long time

A
