There are three generalized categories: Strangulation, Chemical Asphyxia and Suffocation. Most reported murders by asphyxia involve strangulation. An inhaled substance interfering with the body’s ability to use oxygen [e.g. carbon monoxide, butane, and nitrous oxide] characterizes chemical asphyxia.

What are the types of death due to asphyxia?
Drowning accounts for the overwhelming majority of asphyxial deaths in the 1-4 year age group, whereas hanging, strangulation, and drowning are the most common in the 35-44 year age group (see the image below). Prevalence of various types of asphyxial deaths by age groups.
What are the four types of asphyxia?
It is proposed to classify asphyxia in forensic context in four main categories: suffocation, strangulation, mechanical asphyxia, and drowning. Suffocation subdivides in smothering, choking, and confined spaces/entrapment/vitiated atmosphere.
What is death from asphyxia?
Asphyxia is a breathing impairment that occurs when there is insufficient oxygen in the body. This results in decreased delivery of oxygen to the brain and can cause a person to become unconscious or die.
What are the stages of asphyxia?
Two stages of injury can happen with birth asphyxia:
- The first stage happens within minutes if blood flow is low and cells do not get enough oxygen.
- The second stage is called “reperfusion injury.” It can last for days or even weeks. This injury happens after the brain starts getting normal levels of blood and oxygen.
What are the four causes of asphyxiation?
Causes of asphyxiation
- Drowning. Drowning is when a person can’t breathe because they’ve inhaled water.
- Chemical asphyxia. Chemical asphyxia involves inhaling a substance that cuts off the body’s oxygen supply.
- Anaphylaxis.
- Asthma.
- Airway blocked with foreign object.
- Strangulation.
- Incorrect body positioning.
- Seizure.
What is the difference between hypoxia and asphyxia?
Hypoxia is the term used to indicate a deficiency of oxygen. A related term that is often used in relation to perinatal brain injury is anoxia, meaning without oxygen. Asphyxia refers to the physiological results of hypoxia or anoxia.
What is the most common form of asphyxia?
Drowning is the most common type of aspiration. Suffocation (smothering). Suffocation happens when something heavy covers the face or chest and prevents you from breathing. It also occurs when you are in a place where oxygen runs out, such as a closed-in, airtight space.
What causes asphyxia?
Asphyxia can be caused by injury to or obstruction of breathing passageways, as in strangulation or the aspiration of food (choking) or large quantities of fluid (near-drowning or drowning).
How can you tell if someone died from asphyxiation?
There are non-specific physical signs used to attribute death to asphyxia. These include visceral congestion via dilation of the venous blood vessels and blood stasis, petechiae, cyanosis and fluidity of the blood. Petechiae are tiny hemorrhages.
What is perinatal asphyxia?
Perinatal asphyxia is caused by a lack of oxygen to organ systems due to a hypoxic or ischemic insult that occurs within close temporal proximity to labor (peripartum) and delivery (intrapartum).
What are the complications of asphyxia?
Complications of birth asphyxia can include:
- Cerebral palsy.
- ADHD.
- Loss of vision or hearing (or other vision / hearing problems)
- Fetal distress.
- Developmental delays.
- Seizure disorders.
- Hypoxic-ischemic encephalopathy (HIE)
- Periventricular leukomalacia.
What is severe asphyxia?
Asphyxia neonatorum is a condition that occurs when a baby doesn’t get enough oxygen during the birth process. It can be fatal. Another more common name for it is perinatal asphyxia, or birth asphyxia. Hypoxic-ischemic encephalopathy may be a result of severe asphyxia neonatorum.
How does asphyxia affect the brain?
When birth asphyxia is severe, it can injure brain cells and cause potentially fatal conditions, including Hypoxic-Ischemic Encephalopathy (HIE), brain injuries, seizures, and cerebral palsy.
