Hypoxia

Front 1

Def. Hypoxia

Back 1

Inadequate amounts of oxygen to meet metebolic demands of the body

Body converts pyruvic acid into lactic acid

responsible for stiffness after exercise

responsible for decrease on blood PH during cardiac arrest

Front 2

Types of Hypoxia

Back 2

Hypoxemic, Hemic, Stagnant, Histotoxic

Front 3

Def. Hypoxemia

Back 3

Lower than normal amounts of PaO2 in the arterial blood.

Front 4

Causes of Hypoxemia

Back 4

Low Ambient Partial Pressure Oxygen on the atm.

Hypoventilation

True Shunt

Shunt Like

Front 5

Hypoventilation

Back 5

any level of min ventilation which produces higher than normal PaCO2.

Responds of O2 therapy

Front 6

Low Ambient PO2 in Atm.

Back 6

Lower barometric pressures (high altitude)

Lower than normal FIO2

Responds to oxygen therapy

Front 7

True Shunt

Back 7

Blood entering left side of the heart without being oxygenated

Two types: Anatomic and Capillary (consolidation or collapsed)

Does not respond to oxygen therapy

Front 8

Shunt Like Effect

Back 8

Perfusion is in excess of Ventilation however some ventilation is still present

Responds to O2 therapy

Front 9

Hypoxemic Hypoxia

Back 9

Inadequate amounts of O2 in the tissues because of pathological changes in the lung at the a-c membrane

Front 10

Anemic Hypoxia

Back 10

Inadequate amounts of o2 at the tissues due to an inadequate/nonfuctional amount of Hb

Front 11

Stagnant Hypoxia

Back 11

Inadequate amounts of o2 at the tissues due low cardiac output

Front 12

Histotoxic Hypoxia

Back 12

Cells are unable to use oxygen intrecellularly (cyanide poisoning)
