Study Notes
Hyperventilation Overview
- Hyperventilation involves rapid, deep breathing exceeding the body’s metabolic needs.
- Results in the elimination of more carbon dioxide (CO2) than is produced.
Respiration Rates
- Normal adult respiration: 12-20 breaths per minute (RPM).
- Hyperventilation RPM: 22-40 breaths.
Prevalence
- Affects 6-15% of the population.
- More frequent in females aged 30 to 40.
Common Triggers
- High altitudes.
- Pregnancy.
- Central nervous system (CNS) stimulants.
- Aspirin toxicity.
- Anxiety disorders.
Pathophysiology of Hyperventilation
- Characterized by rapid or deep breathing leading to decreased CO2 levels in the blood.
- Results in respiratory alkalosis, increasing blood pH above the normal level of 7.4 to 7.5 or higher.
- Changes occur rapidly, often in less than 30 seconds.
Physiological Effects
- Low CO2 levels trigger vasoconstriction, reducing blood flow to the brain and decreasing cardiac output.
- May lead to syncope (loss of consciousness).
Signs and Symptoms
- Common symptoms include:
- Prolonged rapid and deep breaths.
- Heart palpitations and chest pain.
- Lightheadedness and dizziness.
- Impairment in motor skills and problem-solving.
- Balance and perception disturbances.
- Possible seizures and muscle twitching (tetany).
- Numbness in extremities and around the mouth (circumoral paresthesia).
Additional Symptoms
- Feelings of apprehension and anxiety.
- Profuse sweating (diaphoresis).
- Muscle tremors.
- Fatigue.
- Possible loss of consciousness.
- Sensation of suffocation.
