Auscultation shows crackles or wheezing. Oxygen saturation usually shows hypoxemia. In most cases chest radiological examination shows signs of pulmonary edema, but a significant minority have a normal initial chest X-Ray. [3] Rapid resolution of initial signs and symptoms within 48 hours is typical.
Prolonged exposure to relatively low levels of nitrogen (II) oxide may cause persistent headaches and nausea. [18] Like chlorine gas poisoning, symptoms usually resolve themselves upon removal from further nitrogen dioxide exposure, unless there had been an episode of severe acute poisoning. [19] Treatment and management vary with symptoms.
Some sensors have an air inlet to the sensor in the lead, so contamination from the lead caused by water or oil leaks can be sucked into the sensor and cause failure. [7] Symptoms of a failing oxygen sensor [8] includes: sensor light on dash indicates problem, increased tailpipe emissions, increased fuel consumption, hesitation on acceleration ...

Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...
Oil sludge may occur due to a variety of different factors. Some of the most common causes are: Defective crankcase ventilation system; Oil/coolant contamination; Neglecting oil changes; Low oil level; Poor engine design

Helium may be added to reduce the amount of nitrogen and oxygen in the gas mixture when diving deeper, to reduce the effects of narcosis and to avoid the risk of oxygen toxicity. This is complicated at depths beyond about 150 metres (500 ft), because a helium–oxygen mixture then causes high pressure nervous syndrome. [1]
