- Pulmonary hypoplasia is a condition in which the lungs are abnormally small, and do not have enough tissue and blood flow to allow the baby to breathe on his or her own. Sometimes this problem can be fatal. Most often the pulmonary hypoplasia is a secondary problem due to another diagnosis.

About Pontocerebellar Hypoplasia Summary of Pontocerebellar Hypoplasia. Pontocerebellar Hypoplasia is a group of related conditions that affect the development of the brain. People with these conditions have an unusually small and underdeveloped cerebellum, which is the part of the brain that coordinates movement. A region of the brain called the Pons also fails to develop properly.

Facts about Pulmonary Atresia Pulmonary atresia is a birth defect of the pulmonary valve, which is the valve that controls blood flow from the right ventricle (lower right chamber of the heart) to the main pulmonary artery (the blood vessel that carries blood from the heart to the lungs).

Hypercapnia Hypoventilation is by definition inadequate breathing resulting in impaired gas exchange, meaning that the body is unable to remove carbon dioxide appropriately. The result is an. increase in carbon dioxide levels (hypercapnia) in the blood.

Pulmonary Hypertension Pulmonary hypertension is a condition in which blood pressure in the arteries of the lungs (the pulmonary arteries) is abnormally high. 1  Many disorders can cause pulmonary hypertension. 2  People usually have shortness of breath upon exertion and loss of energy, and some people feel light-headed or fatigued on exertion.

Hypopnea Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause oxygen levels in the blood to drop. It commonly is due to partial obstruction of the upper airway. Hypopnea during sleep is classed as a sleep disorder.

- Definition of Hypoventilation. Hypoventilation: The state in which a reduced amount of air enters the alveoli in the lungs, resulting in decreased levels of oxygen and increased levels of carbon dioxide in the blood. Hypoventilation can be due to breathing that is too shallow (hypopnea) or too slow (bradypnea), or to diminished lung function. The opposite of hypoventilation is hyperventilation (overbreathing).

Hypoxia (medical) Hypoxia exists when there is a reduced amount of oxygen in the tissues of the body. Hypoxemia refers to a reduction in PO2 below the normal range, regardless of whether gas exchange is impaired in the lung, CaO2 is adequate, or tissue hypoxia exists.

Perinatal Hypoxia Hypoxia is a condition when oxygen can’t get to tissue, and perinatal means immediately before and after birth. While the direct translation of perinatal hypoxia means a deficiency of oxygen to the tissue before and after birth, there’s a little more to it than that.

Hypophosphatasia Perinatal hypophosphatasia is the most pernicious form of hypophosphatasia. In utero, profound hypomineralization results in caput membranaceum, deformed or shortened limbs during gestation and at birth and rapid death due to respiratory failure. Stillbirth is not uncommon and long-term survival is rare.

Hypocapnia Hypocapnia or hypocapnea (from the Greek words υπό and καπνός kapnós), also known as hypocarbia, sometimes incorrectly called acapnia, is a state of reduced carbon dioxide in the blood. Hypocapnia usually results from deep or rapid breathing, known as hyperventilation. Hypocapnia is the opposite of hypercapnia.

Hypoventilation In medicine, hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (hypo meaning below) to perform needed gas exchange.

What is Pulmonary Hypertension? The hemodynamic definition of pulmonary arterial hypertension (PAH) is a mean pulmonary artery pressure at rest greater than or equal to 25 mmHg in the presence of a pulmonary capillary wedge pressure less than or equal to 15 mmHg.ulmonary arterial hypertension (PAH) is a progressive disease affecting the arteries of the lungs. The pulmonary arteries are the vessels that carry blood from the right side of the heart through the lungs.

Background Pulmonary atresia with intact ventricular septum (PAIVS) is a rare congenital cardiac lesion characterized by heterogeneous right ventricular development, an imperforate pulmonary valve, and possible extensive ventriculocoronary connections. Prognosis and management depend on the degree of right ventricular hypoplasia (including tricuspid val...

Aplasia Aplasia (from Greek a (not, no); plasis (molding)) is defined in general as defective development or congenital absence of an organ or tissue. In the field of hematology, the term refers to incomplete, retarded, or defective development, or cessation of the usual regenerative process. Examples. Acquired pure red cell aplasia

Focal and Multifocal Lung Disease Part 2 Tropical pulmonary eosinophilia, which is caused by im-munologic hyperreactivity to microfilariae, is characterized by dyspnea, wheezing, and coughing, all of which are worse at night, as well as fever, weight loss, and fatigue [see 14:V Chronic Diffuse Infiltrative Lung Disease].

Pulmonary Atresia (PA) Because of the low amount of oxygen provided to the body, pulmonary atresia is a heart problem that results in cyanosis, or a blue color to the skin from lack of oxygen. The problem occurs as the heart is forming during the first 8 weeks of fetal development.
