Combitube cuff pressure

Distal / esophageal: 12-20 ml
Proximal: 85-140 ml

1

Eft cuff pressure should be no more than what amount? What risk is posed w/ high cuff pressures?

25 mmHg
Mucosal ischemia

2

Men vs women ETT depth in cm

Men: 23 cm at teeth
Women: 21 cm at teeth

3

Tube sizes for pre-term & term new borns

Preterm: 3.0
Term: 3.5

4

ETT diameter (internal) calculation for pediatrics

(Age in years + 16) / 4

5

Rational for us cuffed tubes and age recommendations for pediatrics

Prevents sub glottic stenosis and ulceration
Recommended in Children less than 8 years old

6

Define aerophagia

Swallowing air while crying (pediatrics)

7

CT ETT level

Tip of ETT at T2 to T3 or at level of lower edge of the medial aspect of the clavicle

8

Pediatric needle cric considerations

Laryngeal prominence does not develop until late childhood. Take care to not damage cricoid cartilage (only circumferential structure to support larynx)

9

Needle cric o2 goal

Short bursts high pressure source - 50 psi

10

Succibylcholine & histamine consideration

Release if histamine w/ Succ administration, increases risk of Bronchospasm... Vasodilation?
Vec & Roc = no histamine release

11

Critical blood gas levels

PH less than 7.2
PaCO2 greater than 55
PaO2: less than 60

12

Asthma chest film findings

-Hyperinflated lungs: diaphragm relatively flat, costalphrenic angles are blunt / squared off, very dark fields (hypo dense) / not as many lung markings, costals visible on posterior side.
-Heart is normal sized (pushed a little more mid-line / appears thinner / over inflation of lung is pushing in on heart)
-Also found w/ asthma, COPD, air trapping of any kind.

13

Dead space ventilation vs Venous Admixture

V=Q (1)
DeadSpace: air reaches poorly perfused alveoli
-V>Q (>1)
-PaO2 decreases, PaCO2 increases (ETCO2 decreases?)

Venous Admixture: blood passes through poorly ventilated alveoli. Venous blood mixes w/ arterial.
-V<1)
-PaO2 decreases, normal or low PaCO2

14

Pneumonia: consolidation of what?
Antibiotic should be received within:

Consolidation of proteins, inflammatory factors
Antibiotics within 4 hours.

15

CHF Chest Film Characteristics

-Hypertrophic heart
-R&L sides of heart have shaggy borders (pulmonary tree filled w/ fluid & expanding)
-Cobweb or white lines moving across lungs (Curly A & B lines, vessels engorged w/ fluid, basilar to apex distrubution)

16

ARDS Chest Film

-Cobweb appearance but does not have clear lines as w/ CHF (described as patchy or diffuse)
-hypodense areas (black areas in 1 or both lungs where aeration is taking place. Typically in middle off main bronchi, not in apexes (as w/ CHF)
