What is the most reliable method of confirming and montioring correct placement of
an ET tube?
Continuous waveform capnography
We have an expert-written solution to this problem! The
upper airway consists of...
Nose, Mouth, Jaw, Oral Cavity, Pharynx, and Larynx
No gas exchange occurs here , it's called .
Nose to terminal bronchioles, anatomical dead space. (2ml/kg of inspired tidal volume)
They conduct airflow towards gas exchange units.
Crycothyroid membrane
between thyroid and cricoid, avascular structure that connects the thyroid and cricoid
cartilage. Site of CRiCOTHYROTOMY- an emergency opening of the airway.

A PaCO2 greater than 45 mmHg indicates:
A. Metabolic acidosis.
B. Metabolic alkalosis.
C. Respiratory acidosis.
D. Respiratory alkalosis.
C. Respiratory acidosis
PaCO2 normal range
35-45 mm Hg Less than 35 likely means hyperventilation
Tracheal deviation AWAY from the affected side, decreased breath sounds, and
hyperresonance... What's happening?
Tension pneumothorax
In a tension pneumothorax tracheal deviation goes in what direction?
AWAY from affected side.
Normal mean pulmonary artery pressure
10-20 mmHg
Pulmonary hypertension is a mean PA pressure greater than...

(PAm) greater than 20
Primary pulmonary hypertension
Idiopathic genetic disorder caused by abnormal structure of the pulmonary blood vessels
Name three causes of secondary pulmonary hypertension..
1. Passive PH- the result of back pressure. Mitral Stenosis, LV systolic failure.
2. Active PH- Constriction of the pulmonary circuit Increased volume in
pulmonary circuit (i.e. congenital heart disease)
3. Obstruction as in Chronic recurrent PE
TNP of the Pregnant patient
Resuscitation priorities are the same. The best way to take care of the baby is to take
care of mama
Mechanisms of injury and biomechanics the most common cause of maternal injury
is...
Blunt trauma caused by MVC. Second is BT caused by falls, 3rd is violence
fetal distress is an early sign of maternal distress... Why?
, 4|Page
Catecholamine mediated vasoconstriction resulting from blood loss shunts blood
away from the fetus to the mom.
Fetal hypo perfusion is evidenced by....
Fetal tachycardia (140 to 160+) and fetal bradycardia
The FRC in a pregnant patient is....
Reduced by the gravid uterus lifting the diaphragm.
chest tube placement in a pregnant patient is 1-2 spaces higher Because
of the lifted diaphragm
What is the cause of physiological anemia in pregnant patients?
Hemodilitional anemia occurs. Plasma volume increases 30-50%.
Preterm Labor (PTL)
abruptio placentae
premature separation of the placenta from the uterine wall
