The acardiac twin has no chance of survival. Due to the absence of a beating heart, the acardiac does not send blood to any portion of the placenta, and all of its blood supply comes from and goes back to the circulation of the pump twin through unique vascular connections on the surface of the shared placenta.

What is Pulmonale?

What is cor pulmonale? Cor pulmonale is a condition that most commonly arises out of complications from high blood pressure in the pulmonary arteries (pulmonary hypertension). It’s also known as right-sided heart failure because it occurs within the right ventricle of your heart.

What is hypoventilation?

Hypoventilation is breathing that is too shallow or too slow to meet the needs of the body. If a person hypoventilates, the body’s carbon dioxide level rises. This causes a buildup of acid and too little oxygen in the blood. A person with hypoventilation might feel sleepy.

What is a asphyxia?

Asphyxia happens when your body doesn’t get enough oxygen to keep you from passing out. It can be a life-threatening situation. When you breathe normally, first you take in oxygen. Your lungs send that oxygen into your blood, which carries it to your tissues.

What is the difference between hypercapnia and hypoxemia?

Hypoxemia denotes a blood oxygen concentration or partial pressure of oxygen (PaO2) below normal. Hypoxia also signifies low oxygen levels, but is not restricted to the blood. Hypercapnea denotes a high partial pressure of carbon dioxide (PaCO2).

What does hypercapnia feel like?

Specific symptoms attributable to early hypercapnia are dyspnea (breathlessness), headache, confusion and lethargy. Clinical signs include flushed skin, full pulse (bounding pulse), rapid breathing, premature heart beats, muscle twitches, and hand flaps (asterixis).

Why is there hypocapnia in asthma?

Does hypocapnia lead to hypoxia?

Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety.

How does hyperventilation cause hypocapnia?

If hyperventilation is persistent, it leads to hypocapnia. Hyperventilation refers to an increase in alveolar ventilation that is disproportionate to the rate of metabolic carbon dioxide production, leading to a PaCO2 level below the normal range, or hypocapnia.
