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.
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 ...
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 ...
Arthritis may hinder a cat's ability to get into the litter box in time. Night-time vocalizing is relatively common in hyperthyroid cats or cats with hypertension, which can also cause retinal detachment and blindness, leading to anxiety and confusion. Progressively painful periodontal disease can discourage the cat from visiting its food bowl ...
Cats are natural predators. In fact, some scientists even believe that cats were not so much domesticated by humans, like dogs, cows, horses, and pigeons, but rather that they underwent a process ...
Skin disorders are among the most common health problems in cats and have many causes. The condition of a cat's skin and coat can be an important indicator of its general health. Cheyletiellosis is a mild dermatitis caused by mites of the genus Cheyletiella. It is also known as walking dandruff due to skin scales being carried by the mites ...
