172 Possible Causes for Chronic Hypercapnia

  • Hypercapnia

    These significance bands may be used to separate mixed acid-base disorders in patients with chronic hypercapnia.[nejm.org] Chronic hypercapnia is thought to downregulate carbon dioxide chemoreceptor sensitivity, adversely affecting respiratory function/mechanics and worsening ventilation-perfusion[ncbi.nlm.nih.gov] A recent study by Engel et al. 27 presents data on patients with cystic fibrosis and chronic stable hypercapnia.[nejm.org]

  • Respiratory Acidosis

    Many patients with chronic hypercapnia and respiratory acidosis are also hypoxemic.[emedicine.com] hypercapnia) *COPD pt's are accustomed to increased CO2 levels; a lack of O2 called hypoxic drive stimulates these pt's to breathe -monitor I&O, VS (always include O2 sat[quizlet.com] Acute vs chronic respiratory acidosis Respiratory acidosis can be acute or chronic.[emedicine.com]

  • Acute Respiratory Acidosis

    The defense of pH in groups I and IA was greater than acute hypercapnia in normal man but less than chronic stable hypercapnia ( P 0.05).[annals.org] The Reponse of Extracellular Hydrogen Ion Concentration to Graded Degrees of Chronic Hypercapnia: The Physiologic Limits of the Defense of pH.[vestnik.szd.si] Adequate ventilation is all that is needed to correct respiratory acidosis, although chronic hypercapnia generally must be corrected slowly (eg, over several hours or more[msdmanuals.com]

  • Acidosis

    Many patients with chronic hypercapnia and respiratory acidosis are also hypoxemic.[emedicine.com] Renal: Salt and water retention often attends chronic hypercapnia, especially in the presence of cor pulmonale. 3.[slideshare.net] Acute vs chronic respiratory acidosis Respiratory acidosis can be acute or chronic.[emedicine.com]

  • Hypoventilation

    […] challenged by the fact that only a small fraction of severely obese patients do in fact develop chronic diurnal hypercapnia.[bjmp.org] hypercapnia, daytime PaCO2 6kPa FEV1/FVC 70% Evidence of sleep disordered breathing on overnight studies Tolerated NIV 4hrs on 1st night during initiation of NIV Exclusion[clinicaltrials.gov] Mechanisms by which obesity and OSA result in chronic hypercapnia. HCO3 serum bicarbonate; OSA obstructive sleep apnea.[anesthesiology.pubs.asahq.org]

  • Chronic Respiratory Acidosis

    This appears to contradict frequent observations of normal or near-normal pH levels in patients with chronic hypercapnia.[ncbi.nlm.nih.gov] Adequate ventilation is all that is needed to correct respiratory acidosis, although chronic hypercapnia generally must be corrected slowly (eg, over several hours or more[msdmanuals.com] Renal: Salt and water retention often attends chronic hypercapnia, especially in the presence of cor pulmonale. 3.[slideshare.net]

  • Obesity Hypoventilation Syndrome

    Obesity hypoventilation syndrome (OHS) consists of a combination of obesity and chronic hypercapnia accompanied by sleep-disordered breathing.[ncbi.nlm.nih.gov] […] challenged by the fact that only a small fraction of severely obese patients do in fact develop chronic diurnal hypercapnia.[bjmp.org] hypercapnia , daytime PaCO2 6kPa FEV1/FVC 70% Evidence of sleep disordered breathing on overnight studies Tolerated NIV 4hrs on 1st night during initiation of NIV Exclusion[clinicaltrials.gov]

  • Bronchitis

    Serum electrolytes are of little value but may show an elevated bicarbonate level if patients have chronic hypercapnia.[msdmanuals.com]

  • Acute Bronchitis

    Serum electrolytes are of little value but may show an elevated bicarbonate level if patients have chronic hypercapnia.[msdmanuals.com]

  • High Output Heart Failure

    Hypercapnia caused by chronic obstructive pulmonary disease may also cause high output heart failure.[symptoma.com] High-output heart failure (HOHF) is associated with several diseases including chronic anemia, psoriasis, systemic arteriovenous fistula, sepsis, hypercapnia, multiple myeloma[ncbi.nlm.nih.gov] An elevated cardiac output with clinical heart failure is associated with several diseases including chronic anaemia, systemic arterio-venous fistulae, sepsis, hypercapnia[ncbi.nlm.nih.gov]
