Answer:
Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:
- Oxygenation (PaO₂): hypoxemia
- pH: acidosis
- PaCO₂: Hypercapnia
- HCO₃⁻: normal
whose interpretation is: <u>respiratory acidosis</u>.
Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.
Explanation:
Respiratory acidosis is due to a failure in the breathing process that produces <u>hypoventilation</u>, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.
- <u><em>Acidosis</em></u><em> is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in </em><em>pH</em><em> below 7.35, with no change in bicarbonate content.</em>
- <u><em>Hypoxemia</em></u><em> is the decrease of PaO₂ below 60 mmHg.</em>
- <u><em>Hypercapnia</em></u><em> is the increase of PaCO₂ in ABG above 45 mmHg.</em>
- <em>Normal </em><em>bicarbonate</em><em> </em><em>(HCO₃⁻) </em><em>values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.</em>
<u>Hypercapnia mainly affects the nervous system</u>, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.
Answer:
O. Frequency is measured in Hertz (Hz) and is defined as the number of times a wave peaks per second. Frequency is also known as a measure of EEG power.
The amplitude is the height or peak measurement of the cycle measured from time 0 seconds. Amplitude is measured in macro-volts (uV) and reflects EEG control.
Explanation:
EEG frequency is a term commonly used in the medical field to measure the pulse rat of the brain as well as to diagonise epilepsy. This could be found through the abnomalities in the EEG readings when taken.
Answer:
the data is often incomplete
Answer: True
