Study Notes
Central Nervous System Depressant
- Horizontal Gaze Nystagmus (HGN) is a definitive sign of CNS depressant use.
- Vertical Gaze Nystagmus (VGN) occurs at high doses of CNS depressants.
- Lack of Convergence is commonly observed in individuals under the influence of CNS depressants.
- Pupil size remains normal, indicating typical response (1).
- Reaction to light is slow, demonstrating reduced nervous system responsiveness.
- Pulse rate decreases (down) as a physiological response (2).
- Blood pressure is generally lower, a key indicator of CNS depressants.
- Body temperature tends to be normal, reflecting stable internal condition.
- Muscle tone is flaccid, indicating reduced muscle tension and control.
Inhalants
- Horizontal Gaze Nystagmus is present, suggesting inhalant intoxication.
- Vertical Gaze Nystagmus appears at high doses of inhalants.
- Lack of Convergence is also prevalent among inhalant users.
- Pupil size is described as normal (4), reflecting typical anatomical dimensions.
- Reaction to light is slow, indicating compromised sensory processing.
- Pulse rate tends to be elevated (up), showing increased heart activity.
- Blood pressure can fluctuate (up/down) based on dosage (5).
- Body temperature may vary (up/down/normal) depending on the individual's state.
- Muscle tone can either be flaccid or normal, presenting variability in response.
Dissociative Anesthetics
- Horizontal Gaze Nystagmus is a key indicator of dissociative anesthetic impact.
- Vertical Gaze Nystagmus is noted at high doses, highlighting intense dissociation.
- Lack of Convergence is consistently observed with dissociative anesthetics.
- Pupil size remains normal, suggesting no dramatic alteration from baseline.
- Reaction to light stays normal, indicating intact basic visual processing.
- Pulse rate increases (up) in response to dissociative anesthetics.
- Blood pressure rises (up), a common physiological reaction.
- Body temperature is elevated (up), reflecting the stimulant effect of these substances.
- Muscle tone is rigid, indicating increased muscle tension and potential neuromuscular activity.
