What is the definition of hypoventilation? – ANSWER- – occurs when
alveolar ventilation is inadequate to meet O2 demands
- occurs when alveolar ventilation is not sufficient enough to eliminate
proper CO2 amounts
What is retained during hypoventilation? – ANSWER- – CO2
What does hypoventilation cause? – ANSWER- respiratory acidosis
What is the definition of hyperventilation? – ANSWER- – Lung removes
CO2 faster than it is produced via cellular metabolism
What is hyperventilation caused by? – ANSWER- – severe anxiety - infection
- drugs
- acid-base imbalance
What are some signs / symptoms of hyperventilation? – ANSWER- –
Rapid respiration
- sighing breaths
- numbness / tingling in hands/ feet
- light headedness
- loss of consciousness
What is the definition of hypoxia? – ANSWER- – inadequate tissue
oxygenation at the cellular level.
What does hypoxia result from? – ANSWER- – deficiency in O2 delivery - deficiency of O2 utilization at a cellular level
What can cause hypoxia to occur? – ANSWER- – decreased level of
hemoglobin & lowered O2 carrying capacity of blood - diminished concentration of inspired O2 at higher altitudes
- inability of tissue extraction O2 from the blood (cyanide poisoning)
- decreased diffusion of O2 from the alveoli to the blood (pneumonia)
- poor tissue perfusion w/ oxygenated blood
- impaired ventilation
What sickness / disease can cause hypoxia to occur? – ANSWER- –
pneumonia
What physiological changes to the body can cause hypoxia? –
ANSWER- – cyanide poisoning
- shock
- fractured ribs
- Chest trauma
What are some early signs and symptoms hypoxia? – ANSWER- –
restlessness - apprehension
- decreased level of consciousness (LOC)
- Dizziness
- Behavior changes
What are some early vital sign changes with hypoxia? – ANSWER- –
Blood pressure elevated (unless it is caused by shock)
How does shock impact hypoxia related to Blood pressure? – ANSWER- - Does not increase BP in early signs of blood pressure
What are some late signs and symptoms of hypoxia? – ANSWER- –
Cyanosis - Respiratory rate decreases
What are the two locations you can observe cyanosis in patients with
hypoxia? – ANSWER- – Central cyanosis - Peripheral cyanosis
Where can you see central cyanosis in clients with hypoxia? –
ANSWER- – tongue - soft palate
- Conjunctiva
Where can you peripheral cyanosis in clients with hypoxia? –
ANSWER- – Lower extremities - upper extremities
- nail beds
- earlobes
What is hypoxia a result of ? – ANSWER- – Constriction - stagnant blood flow
What are some factors impacting oxygenation? – ANSWER- – Amount
of dissolved O2 in plasma - Amount of hemoglobin
- Ability of hemoglobin to bind with O2
What vital signs are observed in the late stages of hypoxia? – ANSWER- - respiratory rate decreases
