To prevent cyanosis, attention must be paid to reducing individual risk factors.
Hemoglobin cyanosis
Central cyanosis
Environmental exposures – intoxications
- Carbon dioxide poisoning
- Pesticide poisoning
- Hypobaric hypoxia (exposure to high altitude).
Peripheral localized cyanosis
Environmental stress – intoxications
- Cold
Hemiglobin cyanosis
Carboxyhemoglobinemia
Environmental stress – intoxications
- CO intoxication (CO poisoning).
Methemoglobinemia
Environmental stresses – intoxications [methemoglobin formers]
- Acetanilide
- Aniline dyes
- Amino compounds
- Arsenic
- Benzene derivatives
- Chlorates
- Cyanic compounds
- Dinitrophenol
- Insecticides
- Methylene blue
- Sodium thiocyanate
- Nitrates
- Nitrites
- Nitrobenzene
- Nitrobenzene
- Nitroglycerin
- Nitro compounds
- Nitrous gases
- Paraquat (contact herbicide)
- Phenol
- Smoke inhalation
- Trinitrotoluene
Sulfhemoglobinemia
Medication
- Intoxication with phenacetin
- Intoxication with sulfonamides
Environmental pollution – intoxications
- Hydrogen sulfide
