Presentation
Taken together, the present data revealed that hypoxia can induce lactate secretion and glycolytic efflux by downregulating MPC levels. [ncbi.nlm.nih.gov]
Entire Body System
- Unconsciousness
Most people who make a full recovery have only been briefly unconscious. The longer someone is unconscious, the higher the chances of death or brain death and the lower the chances of a meaningful recovery. [my.clevelandclinic.org]
Most people who make a full recovery were only briefly unconscious. The longer a person is unconscious, the higher the risk for death or brain death, and the lower the chances of recovery. [nlm.nih.gov]
In severe cases of anoxia and hypoxia, from any cause, the patient is often stuperous or comatose (in a state of unconsciousness) for periods ranging from hours to days, weeks, or months. [neuroskills.com]
- Congestive Heart Failure
Hypoxia may be caused by any of the following: Travel to a high altitude Near drowning or choking Carbon monoxide poisoning Exposure to cold for a long period of time Severe anemia Chronic lung disease, such as emphysema Congestive heart failure What [drugs.com]
heart failure Enhancing Healthcare Team Outcomes Hypoxia is low oxygen content at tissue level to meet the metabolic needs of the cells. [ncbi.nlm.nih.gov]
Respiratoric
- Dyspnea
The patient described his dyspnea as exertional progressing over 1 week to rest dyspnea. He was prescribed antiretroviral therapy but was noncompliant. He had no paroxysmal nocturnal dyspnea, orthopnea, rash, oral thrush, or diarrhea. [ncbi.nlm.nih.gov]
Dyspnea Shortness of breath (SOB) is an indication of respiratory distress. Use of accessory muscles Use of neck or intercostal muscles when breathing is an indication of respiratory distress. [opentextbc.ca]
[…] and exercise performance have also been linked to DLco parameters. 52 Moreover, there is a gradual decrease in DLco associated with increasing age 45 in keeping with worsening dyspnea with disease severity. [bloodjournal.org]
- Tachypnea
The patient had hypoxia and tachypnea from pulmonary edema during acute ischemic stroke, which may have accentuated the ischemic change in cerebral hemodynamic. [ncbi.nlm.nih.gov]
Signs and Symptoms Indications Tachypnea Increased respiration rate is an indication of respiratory distress. Dyspnea Shortness of breath (SOB) is an indication of respiratory distress. [opentextbc.ca]
Some of them include: Dizziness or fainting (syncope) Shortness of breath (dyspnea) Confusion, lethargy, and/or lack of judgment Headaches Rapid heart rate (tachycardia) Elevated respiratory rate (tachypnea) Euphoria and a sense of well-being Tingling [verywellhealth.com]
The signs include central cyanosis, frothy sputum, and crackles/wheezing in at least one lung field, tachypnea and tachycardia. 21,23 HAPE is most often misdiagnosed or mistreated as pneumonia. [doi.org]
- Dyspnea at Rest
High‐Altitude Pulmonary Edema HAPE symptoms are dyspnea at rest and especially when attempting to exercise, bothersome cough, weakness, and chest tightness. [doi.org]
Cardiovascular
- Cyanosis
The most common symptom of hypoxia is cyanosis, a bluish cast to the skin, lips and/or fingernails. Cyanosis is harder to observe in dark-skinned people. [ilpi.com]
Late signs of hypoxia include bluish discoloration of the skin and mucous membranes, where vasoconstriction of the peripheral blood vessels or decreased hemoglobin causes cyanosis. Cyanosis is most easily seen around the lips and in the oral mucosa. [opentextbc.ca]
Hypoxia and Hypoxemia Symptoms Cyanosis or Turning Blue Cyanosis is a bluish color of the skin and mucous membranes due to insufficient oxygen in the blood. [medicinenet.com]
It is characterized by the presence of a triggering factor followed by weeping and apnea in expiration accompanied by cyanosis or pallor. [ncbi.nlm.nih.gov]
- Hypotension
Patients with hypotension during resuscitation were 3 times more likely to die compared with those without hypotension. [jamanetwork.com]
Acute severe hypoxia (FIO2=0.10) was tolerated, but adding CO2 to the inspirate caused pre-syncope symptoms accompanied by hypotension and large reductions in both mean and diastolic middle cerebral artery velocity, while systolic flow velocity was maintained [ncbi.nlm.nih.gov]
However, when a hypotensive stress is superimposed during hypoxia, compensatory mechanisms may fail to maintain arterial pressure. Thus, systemic hypoxia interferes with autonomic cardiovascular adjustments. [ahajournals.org]
ALS can result in weakness of the breathing muscles. hypotension asthma Brain hypoxia symptoms range from mild to severe. [healthline.com]

The physical exam may show tachycardia, tachypnea, and low oxygen saturation. Fever may point to infection as the cause of hypoxia. Lung auscultation can yield a lot of useful information. [ncbi.nlm.nih.gov]
Neurologic
- Confusion
[…] skin ranging from blue to cherry red (depending on the causes) Severe symptoms seen with cerebral hypoxia include: confusion, inability to communicate, coma, and may result in death. [medicinenet.com]
- Seizure
After extensive examination and consultation with neurology, the patient was diagnosed with hypoxia-induced seizure, but was not felt to have an underlying seizure disorder. [ncbi.nlm.nih.gov]
Seizure-curbing medicines or anesthetics may also be part of your treatment. Recovering from brain hypoxia depends largely on how long your brain has gone without oxygen. [healthline.com]
When hypoxia lasts for longer periods of time, it can cause coma, seizures, and even brain death. In brain death, there is no measurable activity in the brain, although cardiovascular function is preserved. Life support is required for respiration. [my.clevelandclinic.org]
- Stroke
As the average age in many countries steadily rises, heart infarction, stroke, and cancer become the most common causes of death in the 21st century. [ncbi.nlm.nih.gov]
The evolutionarily conserved hypoxia response plays a crucial role for survival under changing environmental conditions, as well as in diseases, including cancer, ischemia, and stroke. [luschnig.uni-muenster.de]

Serum
- Hemoglobin Increased
Hemoglobin increases the oxygen-carrying capacity of blood by about 40-fold,[19] with the ability of hemoglobin to carry oxygen influenced by the partial pressure of oxygen in the environment, a relationship described in the oxygen–hemoglobin dissociation [en.wikipedia.org]
- Hypocapnia
They are typically associated with periodic breathing owing to alternating respiratory stimulation by hypoxia and subsequent apneas or hypopneas due to inhibition by hyperventilation‐induced hypocapnia. 13 This periodic interruption to breathing results [doi.org]
Arterial blood gas (ABG) Blood gas monitoring is used to assess acid-base status and to avoid hyperoxia and hypoxia as well as hypercapnia and hypocapnia. During the period of shock, capillary blood gases may not be reliable. [emedicine.medscape.com]

Prognosis
CONCLUSION: Overexpression of HIF-1α and P4HB is associated with poor prognosis in patients with GC. Thus, these genes may be potential prognostic biomarker candidates in GC. [ncbi.nlm.nih.gov]
Etiology
Although Hypoxemia may cause of Hypoxia, it is not the only etiology. Reduced Oxygen Delivery Hypoxia can still occur even in contexts of normal blood oxygenation if that blood does not perfuse tissues at a sufficient rate. [pathwaymedicine.org]
Our case report supports the hypothesis that oxygen availability and delivery could play an important role in the regulation of local penile erection-related mechanisms and that low oxygen levels might be considered an etiological cofactor in erectile [ncbi.nlm.nih.gov]
