The Apgar score is a quick way for health professionals to evaluate the health of all newborns at 1 and 5 minutes after birth and in response to resuscitation. [1] It was originally developed in 1952 by an anesthesiologist at Columbia University, Virginia Apgar, to address the need for a standardized way to evaluate infants shortly after birth.
Manifestations: Breathing patterns are often irregular and shallow. The infants respiration rate should be between 30 and 60 breaths per minute with preference for nasal breathing. Ribs expands horizontally. Breath sounds should be clear and equal in both lungs. Abdominal breathing is normal. Acrocyanosis is a normal finding. [1]
A score of 7–10 at 5 minutes is normal, a score of 4 to 6 at 5 minutes is intermediate, and a score of 0-3 is considered low. It is important to understand that an Apgar score is not a diagnosis, it is merely a clinical finding. [9] If a newborns score is 0–3, then resuscitation efforts are initiated. Apgar score for newborn infants
There has long been a scientific debate over whether newborn infants with asphyxia should be resuscitated with 100% oxygen or normal air. [3] It has been demonstrated that high concentrations of oxygen lead to generation of oxygen free radicals, which have a role in reperfusion injury after asphyxia. [4]
Lung volumes and lung capacities are measures of the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such ...
The respiratory rate is the rate at which breathing occurs; it is set and controlled by the respiratory center of the brain. A person's respiratory rate is usually measured in breaths per minute. A person's respiratory rate is usually measured in breaths per minute.
[1] [2] The normal ranges for a person's vital signs vary with age, weight, sex, and overall health. [3] There are four primary vital signs: body temperature, blood pressure, pulse , and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR. However, depending on the clinical setting, the vital signs may include other ...
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk.
