    Exposure of rabbits to 15.5% oxygen during pregnancy resulted in a 17% decrease of birth weight and a neonatal mortality of 19% as opposed to 1% in the control groups, just corresponding to the effects obtained previously by moderate exposure of pregnant rabbits to carbon monoxide. Since additive effects of hypoxia exposure and carbon monoxide exposure are supposed to occur, it is concluded that women living at a high altitude should be warned particularly about the risk of delivering small babies if they have been smoking during their pregnancy.

    Teratogenicity01:07

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
    Hypoxia01:23

    Hypoxia

    Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
    Types of Hypoxia
    There are four primary types of hypoxia, each resulting from a different cause:
    1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
    Acute Respiratory Failure-II01:21

    Acute Respiratory Failure-II

    Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
    The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
