When does cyanosis become visible?
5gm/100ml or 5 gms%
Purpose of secondary polycythemia
Helps increase RBC in order to lower levels of oxygen in the blood
which two types of hypoxia respond well to O2 therapy?
Hypoxemia and Anemic hypoxia
4 typer of hypoxia
hyopxemia, anemic, circulatory, and histotoxic
pulmonary blood is exposed to alveolar gas typically for what time?
0.75 seconds
which type of hypoxia is associated with cyanide poisoning?
Histotoxic, and O2 therapy will not help. Need to administer cyanocobalamin
Whoch types of hypoxia can be treated by oxygen therapy?
hypoxemia and anemic
Circulatory hypoxia is commonly associated with what?
Its commonly assiciated with ischemia
Normal Hgb levels
12-16 gm/dl
A prolonged exposure of FiO2 of >50% can result in what
Oxygen toxicity
how is retinopathy caused?
By giving an infant oxygen and raising the PaO2 greater than 80 mmHg
Actual values for hypoxemia
PaO2 <60mmHg or SaO2 <90%
