47 Possible Causes for Dyspnea with Sudden Onset, PaO2 Decreased

  • Asthma

    Her attacks are characterized by the relatively sudden onset of dyspnea; they are more frequent in the spring and fall, when they are often preceded by symptoms of rhino-conjunctivitis[doi.org]

  • Atelectasis

    .  Pulse oximetry: (SpO2) (less than 90%) or a (PaO2).  Physical examination: Decreased breath sounds and crackles are heard over the affected area. 13.[slideshare.net] Atelectasis was measured by lung density measurements, in Hounsfield units, with computed tomography scans, decreased PaO2 levels (partial pressure of oxygen dissolved in[ncbi.nlm.nih.gov]

  • Acute Respiratory Distress Syndrome

    Definition Acute respiratory distress syndrome (ARDS), is a life-threatening condition which is characterised by the sudden onset of severe dyspnea and hypoxaemia [1].[physio-pedia.com] PaO2/FiO2 ratio (a decreased PaO2/FiO2 ratio indicates reduced arterial oxygenation from the available inhaled gas): mild ARDS: 201 – 300 mmHg ( 39.9 kPa) moderate ARDS:[en.wikipedia.org] (a decreased PaO2/FiO2 ratio indicates reduced arterial oxygenation from the available inhaled gas): · mild ARDS: 201 - 300 mmHg ( 39.9 kPa) · moderate ARDS: 101 - 200 mmHg[faron.com]

  • Congestive Heart Failure

    Metabolic alkalosis, isolated or in combination with another abnormality, is the most common acid-base disorder in patients with congestive heart failure. In most cases, it is a result of diuretic therapy, which causes activation of the renin-angiotensin system, chloride depletion, increased distal sodium delivery,[…][ncbi.nlm.nih.gov]

  • Pulmonary Embolism

    Consecutive patients with clinically suspected pulmonary embolism, defined as a sudden onset of dyspnea, sudden deterioration of existing dyspnea, or sudden onset of pleuritic[doi.org] “In summary, we found that the most reliable indicator of patients with PE is sudden onset dyspnea.[clinicalprediction.com] Symptoms of pulmonary embolism are typically sudden in onset and may include one or many of the following: dyspnea (shortness of breath), tachypnea (rapid breathing), chest[en.wikipedia.org]

  • Acute Massive Pulmonary Embolism

    A73-year-old man was admitted to the intensive care unit because of sudden onset of dyspnea followed by syncope.[circ.ahajournals.org] […] morning of admission, an 89-year-old Caucasian woman with a medical history of dementia, hypertension and chronic obstructive pul- monary disease was noted to experience sudden-onset[pulsus.com] Case Report A 65-year-old man who had a history of hypertension, smoking and drinking alcohol, complained of a sudden onset of dyspnea, chest pain, dizziness, cold sweating[tcmjmed.com]

  • Recurrent Pulmonary Embolism

[3] They become more common as people get older. [3] Signs and symptoms [ edit ] Symptoms of pulmonary embolism are typically sudden[en.wikipedia.org]

  • Pneumococcal Pneumonia

    Abstract The aging of the world population is expected to be accompanied by increased pneumococcal pneumonia in older adults. To address this, the Community-Acquired Pneumonia immunization Trial in Adults (CAPiTA), a large, randomized, placebo-controlled trial conducted to assess the 13-valent pneumococcal conjugate[…][ncbi.nlm.nih.gov]

  • Aspiration Pneumonia

    Aspiration pneumonia is defined as pulmonary infiltration caused by inhaled material, either solid or liquid, that is inherently toxic or that initiates a toxic response. We present the case of a solitary lung mass of unknown etiology in which cytology of a fine needle aspiration provided a definitive diagnosis of this[…][ncbi.nlm.nih.gov]

  • Carbon Monoxide Poisoning

    A 55-year-old man with a medical history of tobacco use suddenly collapsed while power washing an empty indoor pool in a hotel. The decedent was transported to the local hospital where he was pronounced. A postmortem examination revealed atherosclerotic heart disease and bilateral pulmonary edema and congestion.[…][ncbi.nlm.nih.gov]
