Study Notes
Hyperventilation Overview
- Hyperventilation refers to ventilation that exceeds what is necessary to maintain normal arterial blood levels of oxygen (PaO2) and carbon dioxide (PaCO2).
- An apprehensive patient often presents with elevated blood pressure.
Misconceptions and Treatment
- It is incorrect to administer 100% oxygen to patients who are hyperventilating; this is a false belief.
- Benzodiazepines (BZD) are frequently employed to manage anxiety associated with hyperventilation.
Medication Details
- Benzodiazepines are typically delivered intravenously at a rate of 1 mL/min.
- Midazolam is favored over diazepam for intramuscular (IM) administration because diazepam can cause burning sensation when injected IM.
Physiological Effects
- In hyperventilation, rapid breathing leads to a significant drop in carbon dioxide (CO2) levels.
- Proper oxygen administration should occur at a specific flow rate of 5 L/min for optimal results.
