546 Possible Causes for Decreased Oxygen Saturation

  • Asthma

    […] in saturation.[] Beers 2007 showed that BiPAP seemed to improve oxygenation and decrease the respiratory rate, while none of these children experienced a rise in respiratory rate nor a decrease[]

  • Chronic Obstructive Pulmonary Disease

    Supplemental oxygen is recommended in those with low oxygen levels at rest (a partial pressure of oxygen less than 50–55 mmHg or oxygen saturations of less than 88%).[] The saturation should be monitored continuously for at least 5 min after any increase or decrease in oxygen dose to ensure that the patient achieves the desired saturation[] In this group of people, it decreases the risk of heart failure and death if used 15 hours per day and may improve people's ability to exercise.[]

  • Pulmonary Emphysema

    Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1 ), arterial oxygen tension ( P aO 2 ) and arterial oxygen saturation ( S aO 2 ) at rest, and S aO 2 and[] Supplemental oxygen is recommended in those with low oxygen levels at rest (a partial pressure of oxygen less than 50–55 mmHg or oxygen saturations of less than 88%).[] P aO 2 at exercise are significantly decreased in patients with CPFE [ 4, 14, 32 ].[]

  • Pneumonia

    The presence of normal oxygenation (oxygen saturation 96%) decreased the likelihood of pneumonia (LR, 0.47 [95% CI, 0.32-0.67]).[] There is consensus among scientists and clinicians on the life‐saving benefits of oxygen therapy for patients with severe pneumonia and signs of decreased oxygen saturation[]

  • Pulmonary Edema

    Firstly, as pulmonary congestion increases, oxygen saturation decreases, resulting in decreased myocardial oxygen supply.[] saturations, and a sense of impending doom or drowning.[] saturation 16 The pathogenesis of CPO is related to a critical interaction between progressive decrease in left ventricular systolic function and acute increase in systemic[]

  • Myocardial Infarction

    Pulmonary : The pulmonary system is also affected by an MI because there is a decreased level of oxygen saturation due to the damaged heart.[]

  • Traumatic Brain Injury

    Cochrane Database of Systematic Reviews Background Raised intracranial pressure (ICP) is an important complication of severe brain injury, and is associated with high mortality. Barbiturates are believed to reduce ICP by suppressing cerebral metabolism, thus reducing cerebral metabolic demands and cerebral blood[…][]

  • Respiratory Syncytial Virus Infection

    Respiratory syncytial virus infection is a common cause of morbidity and death in pediatric patients. The clinical presentation ranges from mildly symptomatic to life-threatening pneumonia presenting as apnea and respiratory distress. Early suspicion must be mounted whenever respiratory symptoms are seen in young[…][]

  • Chronic Bronchitis

    Therefore, to decrease the likelihood of severe hypercapnea, a safe target oxygen saturation for patients with severe COPD and acute-on-chronic respiratory failure is between[] - are routinely administered oxygen [ 4 ].[] Administration of high oxygen concentrations is therefore likely to decrease brain DO 2.[]

  • Pulmonary Embolism

    oxygen saturation (red blood cells that do not have oxygen molecules attached to them) Decreased blood pressure: hypotension (hypo low tension pressure) The condition progresses[] […] tachy fast cardia heart) Elevated respiratory ( breathing ) rate: tachypnea (tachy fast pnea breathing) Bluish discoloration of skin and mucous membranes (cyanosis), due to decreased[]
