A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates. [2] [3] It consists of a period of tachypnea (rapid breathing, higher than the normal range of 30–60 times per minute). Usually, this condition resolves over 24–72 hours.
The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...
a heart rate that is faster than normal [31] bradycardia: a heart rate that is slower than normal [31] chest recession [32] respiratory distress: the baby has trouble breathing [31] [32] nasal flaring: the baby's nostrils expand when it inhales [32] expiratory grunt: a sound of effort when the baby exhales [32] [34] apnea: the baby stops ...
Hydrops fetalis or hydrops foetalis is a condition in the fetus characterized by an accumulation of fluid, or edema, in at least two fetal compartments. [ 1 ] [ 2 ] By comparison, hydrops allantois or hydrops amnion is an accumulation of excessive fluid in the allantoic or amniotic space , respectively.
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pleurae of the pleural sac that surrounds each lung.A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes, and also to create a pressure gradient.
At this time the fetus is typically about 30 millimetres (1 + 1 ⁄ 4 in) in length from crown to rump, and weighs about 8 grams. [7] The head makes up nearly half of the size of the fetus. [ 8 ] Breathing-like movements of the fetus are necessary for the stimulation of lung development , rather than for obtaining oxygen. [ 9 ]
Many first-time parents also welcome the help of an experienced family member or friend. Having a support person stay with the newborn for a few days can give the mother the confidence to go at it alone in the weeks ahead. This can be arranged before delivery. [1] The baby's first doctor's visit is another good time to ask any infant care ...
