Life Stage Applicability
Key Event Relationship Description
In cases of lethal cholinergic poisoning, mortality results from asphyxiation due to respiratory failure.
Evidence Collection Strategy
Evidence Supporting this KER
A functioning respiratory system is essential for delivering oxygen to organ tissues throughout an organism. Thus, mortality results following respiratory failure.
