1

Before born, lungs are not needed.

True

2

Less than 32-33 weeks of age, baby does not have sufficient amount of surfactant.

True

Biggest change in the NICU is the development of surfactant

If less than 34 weeks 1st dose of surfactant is given at birth

3

Fake surfactant = decrease incidence of -

RDS - Respiratory Distress Syndrome

and

BPD- Bronchopulmonary Dysplasia

4

**** Respiratory Distress Syndrome =

Lack of Surfactant

5

Bronchopulmonary Dysplasia

hard alveoli due to constant ventilator causing positive pressure.

lung tissues get pounded until gets tough

6

Treatment for Apnea of Prematurity

Caffeine

Can give through IV or Orally

Monitor for Toxicity

7

What is Apnea of Prematurity?

pause longer than 20 seconds

Apnea spells can last so long that they cause bradycardia

8

Sudden Infant Death Syndrome (SIDS) interventions:

sleep on back

No Bumpers

pacifier after 1 month

9

A + B Spells =

(Apnea and Brady)

How premie tells us they are sick

If alarm goes off, ASSESS FIRST

Infants breathe periodically- breathe, Breathe, Pause
----Happens in Premature babies

10

Preterm babies =

Bronchiolitis

11

**** S/S of Caffeine Toxicity

vomit

Irritable

Tachycardia

Jittery/ excitability

Tremors

12

Toddlers and Preschoolers breathe abdominally

True

use of abdominal muscles to breathe until 5 years old

13

Infants have irregular breathing patterns and are nose breathers.

True

they have smaller, less rigid airways

smaller lung size

horizontal, short eustachian tubes in Infants

Immature immune systems

14

Surfactant was given in clinical trials and had to stop because was unethical.

True….I guess….

15

What is a late sign of respiratory distress?

Cyanosis

16

Assessing Respiratory Status - VISUAL ASSESSMENT =

- work of breathing such as grunting, flaring, retracting

- Rate of breathing

- Chest Movement- is it equal?

- Posture and activity level - Well Flexed alert and awake**

- Sensorium (LOC)

- Level of comfort

- Color- skin and mucus membranes
- pink? sats in the 90's
- Grey? 80's or lower
- Worried about mucus membranes

17

Assessing Respiratory status - AUSCULTATION

Without the stethoscope you can hear grunting, stridor, or wheezing.

With Stethoscope- inspiratory and expiratory- will usually tell us if it is something in the upper or lower airway

Baby- Listen to Axillae and back

Older listen to front and back

18

While grunting- baby uses abdominal muscles to push air out.

True

19

What are the cardinal signs of respiratory distress?

Tachypnea
Restlessness (Huge sign) , Confusion, Anxiety, Irritability
Tachycardia
Diaphoresis

20

What is the earliest sign of respiratory distress?

Tachycardia

21

What are additional signs of respiratory distress?

Wheezing
grunting, flaring, retracting

22

What are the signs of Impending Respiratory Failure?

Depressed or slow respirations (Decreased inspiratory breath sounds)

Dyspnea

Bradycardia

Somnolence

Stupor/coma

Cyanosis (Central (Mucus membranes)

Oxygen desat

23

What are 2 signs that a baby is about to code?

80's o2 sat

and

Bradycardia

Means about to code…,.

24

O2 Sats falling are a sign of respiratory failure….

true

dont wait for them to become cyanotic

25

Why is tachypnea a sign of respiratory distress?

because if you have trouble breathing, you are going to breathe faster to get more air.

26

Acidosis

pH Less than 7.35

27

Respiratory Acidosis causes =

ventilation problem

need to be ventilated with oxygen

28

Metabolic Acidosis causes =

Diarrhea, Kidney failure, DKA

29

Alkalosis =

pH greater than 7.45

30

Respiratory Alkalosis causes =

test taking, any rapid respiratory rate

to little co2, hyperventilating
