Flashcards in Respiratory Deck (45):
1

Hypercarbia

Retention of CO2

2

Are you breathing fast or slow with hypercarbia?

Slow

3

Loss of sensitivity to high levels of CO2

CO2 narcosis

4

New onset of crackles/decreased breath sounds

Absorption atelectasis

5

Which O2 delivery device doesn't provide enough flow to meet total oxygen and air volume?

Nasal cannula

6

Nasal cannula flow rate

1-6 L/min

7

Nasal cannula O2 concentration

24-44%

8

Why doesn't a flow rate of >6 increase O2 with NC?

Because anatomical dead space is full

9

What device won't increase RR or depth?

NC

10

Simple facemask flow rate

Minimum of 5 L/min

11

FIO2 of simple facemask

40-60%

12

Partial Rebreather flow rate

6-11 L/min

13

Partial rebreather FIO2

60-75%

14

Exhaled tidal volume with partial rebreather

1/3

15

Highest O2 level device

Non-rebreather

16

FIO2 with non-rebreather

>90%

17

When is a non-rebreather used?

For unstable pts who will soon be intubated. If they are requiring that much FIO2 they will wear out.

18

High flow O2 devices FIO2 and flow rate

24-100% at 8-15 L/min

19

Best device for chronic lung dz

Venturi mask

20

Which device delivers precise O2 concentration?

Venturi mask

21

How do pts on venturi mask eat?

Switch to NC

22

Why are T pieces used most often?

To ensure humidification

23

Noninvasive positive pressure vents

BiPAP & CPAP
-Keeps alveoli open to improve gas exchange w/out airway intubation

24

What is BiPAP used for

To keep someone from being intubated or right after they're extubated

25

What is CPAP used for

Sleep apnea, atelectasis after sx, cardiac-induced pulmonary edema

26

Criteria for Home O2 therapy

-Room air sat of

27

Why is it easier to wean a pt off a vent from a trach than with an et tube?

Decreasing the dead space. The et tube is long so every time they breathe they have to overcome pressure

28

What should trach cuff pressure be?

About 20

29

How to do oral care w/ trach

Avoid glycerin swabs or mouthwash with alcohol

30

When is the trach cuff deflated?

When pt can manage secretions, and doesn't need assisted ventilation

31

Odynophagia

Hurts to swallow

32

Inflammation of nasal mucosa

Rhinitis

33

Sinusitis is usually caused by what?

Strep pneumonia, haemophilus flu, diplococcus, bacteroides

34

Inflammation of pharyngeal mucous membranes

Sore throat, pharyngitis

35

Tonsillitis

Airborne, bacterial, ABX for 7-10 days, sx

36

Complication of strep

Epiglottitis

37

RAT

Rapid antigen test for strep, results in 15 mins

38

Causes of rhinitis

Hay fever, allergies

39

Alternative therapy for rhinitis

Vitamin C and zinc

40

Nonsx management of sinusitis

-Broad spectrum ABX
-Steam humidification
-Saline irrigations
-Hot wet packs over sinuses

41

Tx for peritonsillar abscess

Percutaneous needle aspiration of abscess and abx

42

Possible edema of vocal cords w/ what?

Laryngitis

43

Aphonia

Temporary voice loss

44

S/S of laryngitis

Acute hoarseness, dry cough, dysphagia, aphonia

45

Antivirals w/ flu

May be effective if started within 24-48 hrs of s/s
