inhalation
The primary toxicity of pulmonary agents primarily affects the respiratory system and can lead to severe lung injury. Exposure to smoke particles, vapors, or gases can cause inflammation, pulmonary edema, and impaired gas exchange. This toxicity can result in symptoms such as coughing, difficulty breathing, and in severe cases, respiratory failure. Long-term exposure may also lead to chronic respiratory conditions.
Pulmonary agents can affect the body by acting on the respiratory system. They can cause bronchoconstriction, inflammation, or other changes that impact lung function and breathing. Long-term exposure to these agents can lead to respiratory diseases and other health problems.
Pulmonary Oxygen Toxicity (PO) and Central Nervous System Toxicity (CNS)
Pulmonary oxygen toxicity is caused by divers exposing themselves to elevated partial pressures of oxygen for long periods of time, and is primarily a concern for technical divers who decompress on oxygen. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure.
The first one is primary because it's stressed.

Flushing
Flushing, vasodilation, and itching are the primary indicators.
Pulmonary agents primarily enter the victim through inhalation, where the toxic substance is breathed into the lungs and absorbed into the bloodstream. These agents can cause damage to the respiratory system and lead to serious health consequences.
Pulmonary agents can cause pulmonary edema by disrupting the normal balance of fluid in the lungs, leading to fluid accumulation in the air sacs (alveoli) and interstitial spaces. This can result from mechanisms such as increased capillary permeability, inflammation, or increased hydrostatic pressure in the pulmonary circulation. Ultimately, this leads to impaired gas exchange and breathing difficulties.
