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?
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
