Hypoxia is treated with oxygen therapy that can take several dys to wean. Illness can last 2-4 wks. ...Read more
Hypoxia, is a condition in which the body as a whole or a region of the body is deprived of adequate oxygen supply. It is classified into 4 groups: - hypoxemic - oxygen is low - anemic - decreased ability for hemoglobin to carry oxygen. - ischemic - decreased blood flow. - histotoxic - oxygen is reaching the cells, but the cells are unable to use ...Read more
Hypoxia: Oxygen is required for tissues to burn their fuel, just like a fire burning a log. The human system can compensate for mild low o2 by breathing faster, equal to u blowing on the fire to help it burn. If the o2 is so low breathing faster doesn't get enough or the body becomes exhausted in the effort, the metabolism shuts down, equal to the fire going out. ...Read more
Pre & post natal: The fetal or newborn heart requires significant amounts of oxygen to function &diminished levels quickly show up as a slowed heart beat (part of what's monitored in labor). If it is kept at low levels over long period the hearts electrical system may develop a rhythm problem. The most common is prolonged bradycardia from which the fetus/infant may not recover. ...Read more

It varies: Near the end of the 2nd trimester, certain areas of the fetal brain are particularly susceptible to drops in oxygen/ low blood flow, which can be caused by maternal conditions that necessitate early delivery for the safety of the mother or because fetal well-being is found to be compromised. Ob's get those babies out asap & neonatologists try to prevent further hypoxia, but the die may be cast. ...Read more
Multiple factors: Multiple factors determine the recovery from hypoxia in neonates with pneumonia. Premature neonates are at greatest risk due to underlying prematurity related lung disease. Other factors include maternal fever or chorioamnionitis, premature rupture of membranes, sepsis, duration of mechanical ventilation, nosocomial infections, congenital heart disease etc. Discuss with your neonatologist. ...Read more
Bronchiolitis: Bronchiolitis is caused by viruses. The most common virus causing severe disease is the RSV or respiratory syncyitial virus. Since your baby continues to show poor oxygenation, especially if the wheezing is severe and he is having difficult breathing, your baby may need to be admitted to the hospital for more intense treatment. Please talk to your pediatrician. ...Read more
This really depends on the patient. For normal patient who does not smoke very low oxygen level could be defined as an oxygen saturation less than 88% or a partial pressure of oxygen measured in blood gas less than 60 mmhg. For an active smoker these numbers may be different. For someone with underlying lung disease again these ...Read more
