    The article deals with 140 cardiotocographic curves during opening and 147 curves during expulsion in puerpera in whom delivery was performed under cardiotocography and pH-metry. During different changes of foetal heart frequency pH values of foetal blood were determined. On the basis of cardiotocographic changes the examined group was divided into several subgroups. In each group the mean values of current pH were compared with the mean values of the control group. The control group consisted of 41 cardiotocographic curves during opening and 41 during expulsion in patients with normal delivery and clear foetal liquid. The pH of foetal blood was determined during opening and expulsion. Mean pH values of foetal blood were significantly lower during opening with expressed variable DIP-I and DIP-II as well as with slight and strong bradicardy. During expulsion a significant fall of mean pH values was observed only in the group with expressed variable DIP-I and DIP-II. Consequently the Apgar score of newborn infants was reduced. The mean pH values in other cardiotocographic changes were decreased but statistically insignificant. The same was observed in Apgar score.

    Fetal Circulation01:14

    Fetal Circulation

    Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
    Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

    Assessment of Diffusion and Perfusion

    Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
    The Role of Diffusion in Respiration
    Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...

    Blood Studies I: ABG and VBG

    Blood studies are critical in the medical field, enabling healthcare professionals to assess a patient's health status accurately. This page will focus on two significant blood studies: Arterial Blood Gas (ABG) and Venous Blood Gas (VBG).
    Arterial Blood Gas (ABG)
    Arterial Blood Gas (ABG) studies are crucial for assessing the lungs' ability to supply oxygen and remove carbon dioxide, reflecting the patient's ventilation status. They also help understand the kidneys' capacity to reabsorb or...
    Electrocardiogram01:29

    Electrocardiogram

    An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
    Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...
