3,990 Possible Causes for Hypoxia

  • Morbid Obesity

    The risk of postoperative hypoxia is increased by preoperative hypoxia and by any surgery involving the thorax or abdomen.[] Therapy subsequently was changed to linezolid, because the patient's clinical status worsened, with significant hypoxia (partial pressure of arterial oxygen/fraction of inspired[] This can cause ventilation-perfusion mismatch, right-to-left shunting and arterial hypoxia. Dead space is unchanged.[]

  • Atelectasis

    OBJECTIVE: Role of the atelectasis (hypoxia) in the respiratory system of the live and exited newborn (250 up to 3000 g. of body weight), which has died due to different causes[] English s collapsed lung ( atelectasis ); lack of oxygen in the body (hypoxia); congestion; cough; noisy or More by Other dictionary words[] However, its effect on mortality, hypoxia or invasive ventilation is uncertain.[]

  • Asthma

    Vasoconstriction due to alveolar hypoxia also contributes to this mismatch. Vasoconstriction is also considered an adaptive response to ventilation/perfusion mismatch.[] In the early stages, when ventilation-perfusion mismatch results in hypoxia, hypercarbia is prevented by the ready diffusion of carbon dioxide across alveolar capillary membranes[]

  • Chronic Obstructive Pulmonary Disease

    Presence of chronic hypoxia or cor pulmonale.[] Because of low cardiac output, however, the rest of the body suffers from tissue hypoxia and pulmonary cachexia.[] The respiratory drive is normally largely initiated by PaCO 2 but in COPD hypoxia can be a strong driving force, which can therefore be reduced if the hypoxia is corrected[]

  • Pulmonary Edema

    RESULTS: Compared with control subjects, numerous hypoxia-related genes were up-regulated in patients with acute HAPE.[] HAPE triggered by concurrent respiratory tract infection and strenuous exercise in a mining worker with an abnormal rise in pulmonary artery pressure in response to acute hypoxia[] S acin and S cond did not change significantly in hypoxia ( P 0.56 and 0.19, respectively).[]

  • Sleep Apnea Syndrome

    We here report the case of a 36-year-old man with severe OSAS who experienced the recurrence of stroke due to nocturnal hypoxia and a nocturnal BP surge measured by this trigger[] Furthermore, PPAR-α is also reduced by hypoxia.[] Oxygen administration improved nocturnal hypoxia and reduced the AHI, which was 40 /- 20 with oxygen and 58 /- 17 with air (p 0.005).[]

  • Respiratory Syncytial Virus Infection

    Hypoxia, wheezing, stridor, nasal flaring and chest wall in-drawing had sensitivities ranging from 8 to 31 %, but had specificities 75 %.[] Characterised by cough, wheeze, respiratory distress, and hypoxia. Most episodes are mild and self-limiting.[] The alternative case definition (cough or difficulty breathing plus hypoxia, in-drawing, or wheeze) had a sensitivity of [55 %, 95 % CI (50-59)] and a specificity of [60 %[]

  • Cor Pulmonale

    The first cause of increased PVR is chronic long-standing alveolar hypoxia which induces pulmonary vascular remodeling.[] Abstract Hypoxia and endothelial dysfunction play a central role in the development of pulmonary hypertension.[] Cor pulmonale is a complication of hypoventilation-induced hypoxia and hypercapnia and had not yet been reported in BVVLS.[]

  • Congestive Heart Failure

    As well, the infant from the high altitude area showed better adaptability to hypoxia.[] […] vera, thyrotoxicosis CHF precipitants Alcohol, cor pulmonale, drug-related–inappropriate medications, non-compliance, fluid and/or sodium intake, fever, hypothyroidism, hypoxia[] Dyspnea Loop diuretics with or without thiazides 60 Inotropes 64 Oxygen (without hypoxia) 69 Benzodiazepines 70 Acupuncture/ acupressure 67 Nitrates 61 Aquapheresis (if diuretic[]

  • Myocardial Infarction

    10 minutes of hypoxia and a sustained activation that starts after two hours of hypoxia. 113 In this model, ERK2 and JNK are not activated.[] It can be manifested as a primary hypoxic symptom, or cause the exacerbation of underlying diseases due to hypoxia.[] […] significantly increased sirtuin (SIRT) 3 level (2.7-fold) in vivo while the inhibition of SIRT3 exacerbated senescent H9c2 cellular LDH release and ROS production under hypoxia[]
