Nitrogen had been used to flush oxygen from the compartment as a precaution against fire. They were not wearing air packs because of a last-minute change in safety procedures. [23] During a pool party in Mexico in 2013, eight party-goers were rendered unconscious and one 21-year-old male went into a coma after liquid nitrogen was poured into ...
Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where sufficiently ...
If large amounts of air leak into the tissues around the head, the face can swell considerably. [8] In cases of subcutaneous emphysema around the neck, there may be a feeling of fullness in the neck, and the sound of the voice may change. [10] If SCE is particularly extreme around the neck and chest, the swelling can interfere with breathing.
The disorders are caused by breathing gas at the high pressures encountered at depth, and divers will often breathe a gas mixture different from air to mitigate these effects. Nitrox , which contains more oxygen and less nitrogen , is commonly used as a breathing gas to reduce the risk of decompression sickness at recreational depths (up to 34 ...
An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation (suffocation).
A wide esophagus due to trapped air. This is common in R-CPD and causes chest pains, gurgles and other symptoms.This was done using an ENT scope without insufflated air. Retrograde cricopharyngeus dysfunction (R-CPD) is a medical condition first identified by Dr Robert Bastian of the Bastian Voice Institute in which people are unable to burp. [1]

Atmospheric nitrogen has a partial pressure of approximately 0.78 bar at sea level. Air in the alveoli of the lungs is diluted by saturated water vapour (H 2 O) and carbon dioxide (CO 2), a metabolic product given off by the blood, and contains less oxygen (O 2) than atmospheric air as some of it is taken up by the blood for metabolic use. The ...
