Exempel på hur man kan använda HYPERCAPNIA i en mening

• A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia.
• In physiology, a chemoreceptor detects changes in the normal environment, such as an increase in blood levels of carbon dioxide (hypercapnia) or a decrease in blood levels of oxygen (hypoxia), and transmits that information to the central nervous system which engages body responses to restore homeostasis.
• Specific symptoms attributable to early hypercapnia are dyspnea (breathlessness), headache, confusion and lethargy.
• Without intervention, both may lead to decreased oxygen in the blood (hypoxemia), elevated carbon dioxide level in the blood (hypercapnia), inadequate oxygen perfusion to tissue (hypoxia), and may be fatal.
• Hypoventilation in COPD involves multiple mechanisms, including decreased responsiveness to hypoxia and hypercapnia, increased ventilation-perfusion mismatch leading to increased dead space ventilation, and decreased diaphragm function secondary to fatigue and hyperinflation.
• The permissive hypercapnia leads to respiratory acidosis which might have negative side effects, but given that the patient is in ARDS, improving ventilatory function is more important.
• There is a wide range of potential causes including head injury, interruption of blood circulation, impaired oxygenation or carbon dioxide toxicity (hypercapnia), central nervous system (CNS) infections, drug intoxication or withdrawal, post-seizure state, hypothermia, and metabolic derangements such as hypoglycemia, hyponatremia, and hypercalcaemic crisis.
• On the other hand, asphyxiation is technically incorrect given respiration continues and the carbon dioxide metabolically produced from the oxygen inhaled prior to inert gas asphyxiation can be exhaled without restriction, which can prevent acidosis and the strong urge to breathe caused by hypercapnia.
• The effects of hyperventilation, work, breathing mixture and dive depth on immersed breath-hold duration were investigated to allow an increase in breath-hold time to a maximum safe level without excessive risk of loss of consciousness or functional incapacity due to hypocapnia, hypoxia or hypercapnia.
• For example, a fall in arterial pO2 (hypoxemia) or an increase in arterial pCO2 (hypercapnia) leads to an increase in the rate and depth of respiration through activation of the chemoreceptor reflex.
• When the user inhales, some of the previously exhaled air which remains in the dead space is inhaled again, reducing the amount of fresh air in the inhaled volume, which increases the risk of hypercapnia, a buildup of carbon dioxide in the blood.
• They vary in their efficiency, in that some need wastefully higher fresh gas flows in certain situations to ensure that carbon dioxide is removed safely, avoiding rebreathing that can lead to hypercapnia.
• The processing device monitors heart beat data, and executes a heart rate variability program to detect physiological distress, essential in the prevention of hypercapnia, hyperoxia, and decompressive stress.
• Chronic secondary headache or orofacial pain can be caused by ischemic stroke, nontraumatic intracranial hemorrhage, arteritis, unruptured vascular malformation, pituitary apoplexy, genetic vasculopathy, increased cerebrospinal fluid pressure, Chiari malformation type I, intracranial neoplasms, epileptic seizure, substance withdrawal, bacterial meningitis, meningoencephalitis, viral meningitis or encephalitis, brain abscess, intracranial fungal or other parasitic infections, hypoxia, hypercapnia, dialysis, arterial hypertension, and hypothyroidism.
