What are the six classification of asphyxia?

For the purpose of this study, the term “suffocation” was applied to deaths due to simple (environmental) asphyxia, smothering, choking, traumatic (mechanical) asphyxia, positional asphyxia and combinations of the aforementioned, which is the classification used by most authors [1] [4] [5][6]. …

What are the two types of asphyxia?

In this Article
  • Physical Asphyxia.
  • Chemical Asphyxia.

What are the stages of asphyxia?

If asphyxia is considered pathophysiologically, there are four stages where the transfer of oxygen can be compromised; i.e., oxygen reduction at the cellular level may be caused by (1) decreased amounts of oxygen in the environment, (2) reduced transfer from the air to the blood, (3) reduced transport from the lungs to …

What are the main causes of asphyxia?

Asphyxiation is caused by lack of oxygen. It can quickly lead to loss of consciousness, brain injury, or death. Some causes of asphyxiation include drowning, asthma, and choking. Asphyxiation is often caused by accident.

What is birth asphyxia classification?

Severe birth asphyxia: No breathing at 1-minute of age. Definition II (For intramural babies) Birth asphyxia: Apgar score of less than 7 at 1 minute of age Moderate birth asphyxia: Apgar score between 4 to 6 at 1-minute of age Severe birth asphyxia: Apgar score of 3 or less at 1-minute of age.

What is the most common type of asphyxia?

Prevalence of various types of asphyxial deaths by age groups. 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.

What are the types of asphyxia death?

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 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’s the difference between asphyxiation and suffocation?

Asphyxiation can occur when a substance, such as carbon dioxide, interferes with the oxygenation of tissue. Suffocation can occur when the air supply to the body is blocked from entering the body. Unfortunately, the results can be the same – death.

What are the 3 types of asphyxia?

It is proposed to classify asphyxia in forensic context in four main categories: suffocation, strangulation, mechanical asphyxia, and drowning.

What are the four types of hypoxia?

Hypoxia is actually divided into four types: hypoxic hypoxia, hypemic hypoxia, stagnant hypoxia, and histotoxic hypoxia.

What is compression asphyxia?

Compression asphyxia is a type of mechanical asphyxia, where respiration is prevented by external pressure on the body, at the same time inhibiting respiratory movements and compromising venous return from the head. 1. It is usually due to heavy weight compressing the chest or the abdomen.

How is asphyxiation determined?

The classical signs of asphyxia mentioned (petechial hemorrhages of the conjunctivae, viscera and/or skin, cerebral and/or pulmonary edema, visceral congestion, the fluidity of the blood) have been used in the diagnosis of asphyxial death for many years.

What is asphyxia in legal medicine?

Forensic Medicine/Causes of Death

Asphyxia, a term literally meaning absence of the pulse in Greek, has come to be used in Forensic Medicine for events, and particularly deaths, where there has been deprivation of oxygen.

What is position asphyxiation?

Positional asphyxia, is also known as postural asphyxia, is a form of asphyxia which occurs when someone’s position prevents them from breathing adequately. A small but significant number of people die suddenly and without apparent reason during restraint by police, prison (corrections) officers and health care staff.

What is the medico legal importance of determining death?

Death investigations provide evidence to convict the guilty and protect the innocent, whether they are accused of murder, child maltreatment, neglect, or other crimes. Death investigations aid civil litigation, such as in malpractice, personal injury, or life insurance claims.

Is asphyxiation a mechanism of death?

We conclude that violent asphyxia remains to be a quite commonly cause of death in the practice of forensic pathologists – among all the autopsies performed in 2010 every sixth was of an asphyxia victim.

How can you prevent asphyxiation?

Always lay an infant down on their back on a firm mattress. Never place an infant on soft surfaces such as comforter, fluffy rug, or soft mattress. Never put an infant down on a mattress covered with plastic. Keep blankets, pillows, stuffed animals, or plush toys out of the crib.

What is silent asphyxiation?

Positional asphyxia snatches innocent lives without warning signs everyday, and it happens to even the most careful of parents. There is no gasping for breath or screaming and wailing — it is the silent killer.
