Examples of chest compression include the knee-on-stomach position; or techniques such as leg scissors (also referred to as body scissors and in budō referred to as do-jime; 胴絞, "trunk strangle" or "body triangle") where a participant wraps his or her legs around the opponents midsection and squeezes them together.Pressing is a form of torture or execution using compressive asphyxia. Perinatal asphyxia
Perinatal asphyxia is the medical condition resulting from deprivation of oxygen (hypoxia) to a newborn infant long enough to cause apparent harm. It results most commonly from a drop in maternal blood pressure or interference during delivery with blood flow to the infants brain. This can occur as a result of inadequate circulation or perfusion, impaired respiratory effort, or inadequate ventilation. There has long been a scientific debate over whether newborn infants with asphyxia should be resuscitated with 100% oxygen or normal air. It has been demonstrated that high concentrations of oxygen lead to generation of oxygen free radicals, which have a role in reperfusion injury after asphyxia. Research by Ola Didrik Saugstad and others led to new international guidelines on newborn resuscitation in 2010, recommending the use of normal air instead of 100% oxygen. Mechanical asphyxia
Classifications of different forms of asphyxia vary among literature, with differences in defining the concept of mechanical asphyxia being the most obvious.In DiMaio and DiMaios 2001 textbook on forensic pathology, mechanical asphyxia is caused by pressure from outside the body restricting respiration.
If the performed actions were not effective, repeat them until you free respiratory tract of the affected person from a foreign body. See also
Asphyxiant gas – Nontoxic or minimally toxic gas which can displace oxygen in breathing air
Erotic asphyxiation – Intentional restriction of oxygen to the brain for sexual arousal
Hypercapnia – Abnormally high tissue carbon dioxide levels
Respiratory acidosis – Medical condition
