Flashcards in Airway#2 Deck (17):
Combitube cuff pressure
Distal / esophageal: 12-20 ml
Proximal: 85-140 ml
Eft cuff pressure should be no more than what amount? What risk is posed w/ high cuff pressures?
Men vs women ETT depth in cm
Men: 23 cm at teeth
Women: 21 cm at teeth
Tube sizes for pre-term & term new borns
ETT diameter (internal) calculation for pediatrics
(Age in years + 16) / 4
Rational for us cuffed tubes and age recommendations for pediatrics
Prevents sub glottic stenosis and ulceration
Recommended in Children less than 8 years old
Swallowing air while crying (pediatrics)
CT ETT level
Tip of ETT at T2 to T3 or at level of lower edge of the medial aspect of the clavicle
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)
Needle cric o2 goal
Short bursts high pressure source - 50 psi
Succibylcholine & histamine consideration
Release if histamine w/ Succ administration, increases risk of Bronchospasm... Vasodilation?
Vec & Roc = no histamine release
Critical blood gas levels
PH less than 7.2
PaCO2 greater than 55
PaO2: less than 60
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.
Dead space ventilation vs Venous Admixture
DeadSpace: air reaches poorly perfused alveoli
-PaO2 decreases, PaCO2 increases (ETCO2 decreases?)
Venous Admixture: blood passes through poorly ventilated alveoli. Venous blood mixes w/ arterial.
-PaO2 decreases, normal or low PaCO2
Pneumonia: consolidation of what?
Antibiotic should be received within:
Consolidation of proteins, inflammatory factors
Antibiotics within 4 hours.
CHF Chest Film Characteristics
-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)
