A form of asphyxia due to body position

Positional asphyxia[edit]

Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents them from breathing adequately. This condition can occur in various situations, often involving restraint or confinement, where the body is positioned in such a way that it impairs the ability to breathe.

Causes[edit]

Positional asphyxia can be caused by several factors, including:

Body position: Certain positions can compress the chest or abdomen, restricting the movement necessary for breathing. For example, lying face down (prone position) can impede chest expansion.
Weight on the body: External pressure, such as a person kneeling on another's back, can exacerbate the restriction of breathing.
Physical restraint: Restraint techniques that involve holding a person in a specific position can lead to positional asphyxia if not carefully monitored.

Mechanism[edit]

The mechanism of positional asphyxia involves the restriction of the diaphragm and chest wall movement, which are essential for ventilation. When the diaphragm cannot move downward effectively, and the chest cannot expand, the lungs cannot fill with air, leading to decreased oxygen intake and potential hypoxia.

Risk factors[edit]

Several risk factors can increase the likelihood of positional asphyxia, including:

Obesity: Excess body weight can increase the pressure on the chest and abdomen.
Intoxication: Alcohol or drug use can impair a person's ability to reposition themselves or communicate distress.
Medical conditions: Pre-existing respiratory or cardiovascular conditions can make individuals more susceptible.

Prevention[edit]

Preventing positional asphyxia involves:

Training: Proper training for law enforcement and security personnel on safe restraint techniques.
Monitoring: Continuous monitoring of individuals in restraint to ensure they can breathe adequately.
Positioning: Avoiding prone positions and ensuring that the chest and abdomen are not compressed.

-'''Positional Asphyxia''' is a condition that occurs when a person's position prevents them from breathing adequately. This can happen in various situations, such as when a person is restrained or trapped in a confined space. The lack of oxygen can lead to unconsciousness or death if not promptly addressed.

-* Being restrained, such as during law enforcement or mental health interventions
-* Certain sleeping positions, particularly in infants ([[Sudden Infant Death Syndrome|SIDS]])
-* Prolonged pressure on the chest or abdomen
-* Obesity, which can restrict the diaphragm
-== Symptoms ==
+==Causes==
-Symptoms of positional asphyxia can vary depending on the severity of the condition. They may include:
+Positional asphyxia can be caused by several factors, including:
-* Difficulty breathing
-* Rapid heartbeat
-* Sweating
-* Feeling lightheaded or faint
-* Confusion or disorientation
-* Loss of consciousness
-== Prevention ==
+* '''Body position''': Certain positions can compress the chest or abdomen, restricting the movement necessary for breathing. For example, lying face down (prone position) can impede chest expansion.
-Prevention of positional asphyxia involves avoiding situations where the body's position can interfere with breathing. This may include:
+* '''Weight on the body''': External pressure, such as a person kneeling on another's back, can exacerbate the restriction of breathing.
-* Using appropriate techniques and precautions when restraining individuals
+* '''Physical restraint''': Restraint techniques that involve holding a person in a specific position can lead to positional asphyxia if not carefully monitored.
-* Ensuring infants sleep on their backs and not on their stomachs or sides
-* Avoiding tight, restrictive clothing or gear
-* Maintaining a healthy weight
-== Treatment ==
+==Mechanism==
-Treatment for positional asphyxia involves removing the person from the position causing the asphyxia and providing immediate medical attention. This may include:
+The mechanism of positional asphyxia involves the restriction of the [[diaphragm]] and chest wall movement, which are essential for [[ventilation]]. When the diaphragm cannot move downward effectively, and the chest cannot expand, the lungs cannot fill with air, leading to decreased oxygen intake and potential [[hypoxia]].
