A high arterial partial pressure of carbon dioxide causes changes in brain activity that adversely affect both fine muscular control and reasoning. EEG changes denoting minor narcotic effects can be detected for expired gas end tidal partial pressure of carbon dioxide ( P E T C O 2 {\displaystyle {P_{ET_{CO_{2}}}}} ) increase from 40 torrs (0. ...
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate , abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. [1] Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (symbol COHb or HbCO) preventing the blood from carrying oxygen and expelling carbon dioxide as carbaminohemoglobin.

Cancer is the number-one disease-related killer of cats and dogs. Many cancer symptoms in cats are subtle and can be caused by another condition, but if you notice any of the following potential ...
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
We asked New Zealand-based veterinarian, Dr. Lianne Mellin, BVSc (Hons), to find out specific signs your cat might think of you as a parent. Right away, Dr. Mellin, who prefers to be called "Dr ...
Common symptoms are often flulike and include headache, dizziness, upset stomach, chest pain or confusion, but highly concentrated levels of CO can cause a person to pass out without feeling symptoms.
