    Uterine contractions during delivery increase the resistance to flow in the blood vessels of the placenta and decreases placental blood circulation, possibly subjecting the fetus to hypoxia. Several methods have been developed for monitoring the condition of the fetus during delivery. Cardiotocography is used to monitor the fetus's heart rate and variability in relation to the mother's contractions. A change in cardiotocography recording due to stimulation of the presenting part is an indication of a healthy fetus. ST analysis of fetal ECG depicts the oxygenation of fetal cardiac muscle during delivery. In addition to cardiotocography and ST analysis, analysis of blood gases and lactate determination are used in assessing the condition of the fetus.

    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...

    Pulse rhythm01:30

    Pulse rhythm

    Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
    Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

    Cardiomyopathy VII: Pre and Post Operative Nursing Management

    Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
