hypoventilation decreased rate or depth of air movement into the
lungs
Causes excessive CO2 retention= respiratory
acidosis & respiratory arrest
S/S: mental status change, dysrhythmias, cardiac
arrect, convulsions, unconsciousness, death
hyperventilation increased rate and depth of breathing
Causes: severe anxiety, infection, drugs, acid-base
imbalance
S/S: rapid respirations, sighing breaths,
numbness/tingling of extremities, light-
headedness, LOC
hypoxia lack of oxygen at the cellular level
-check HgB levels
, hypoxia cause -decreased hemoglobin and lowered oxygen-
carrying capacity of the blood;
-diminished concentration of inspired oxygen
(high-altitude);
-inability of tissues to extract oxygen from the
blood (cyanide poisoning);
-decreased diffusion of oxygen from alveoli to the
blood (pneumonia);
poor tissue perfusion with oxygenated blood
(shock)
-impaired ventilated (chest trauma)
early signs of hypoxia Restlessness
Agitation
Tachycardia
-inc BP and RR
late signs of hypoxia Bradycardia
Extreme restlessness
Dyspnea
-dec RR
cyanosis bluish discoloration of the skin due to lack of
oxygen
NOT a reliable sign of hypoxia
central cyanosis observed on tongue, soft palate, conjunctiva.
peripheral cyanosis seen in extremities, nail beds, earlobes
(vasoconstriction)
what influences the capacity of 1. amount of dissolved O2 in plasma
blood to carry O2 2. amount of HgB
3. ability of HgB to bind with O2
