At this point the school age child (age 6 – 12) and the adolescent (13 to 18) brain is working on both hemispheres. This age group can be extremely creative and extremely logical (both at the same time). School age children are constantly dealing with losing their baby teeth and dealing with the pain that […]

All is not lost on the middle aged person (age 41 – 60). Middle aged people tend to be more conservative in their approaches to life, often approaching life’s problems as challenges as opposed to threats. Middle aged people sometimes struggle with the passage of their own children into adulthood. This lack of familial interaction […]

Situational Crisis – Personal Separation Reactions Researchers observed that when a child was separated from their primary caregiver (typically their mother) all children seemed to progress through three stages: The protest stage: The initial response of virtually all children to being separated from their caregiver is protest. Protest, for young children and infants, can show […]

Fetus Under Tremendous Pressure In order to deliver a complete baby out of a vagina, the newborn must be highly compressible. In order to be delivered, the fetus has to be squeezed to 1/2 to 1/3 it’s normal diameter. The ability to be crushed is a fascinating trait that follows the newborn all the way […]

Newborns actually drop about 5 to 10 percent of their initial body weight in the first week of life. Within a few minutes of birth, the neonatal pulse is usually 30 – 40 beats per minute slower; likewise, the neonatal respiratory rate normally drops to under 40 breaths a minute. The decrease in breaths per […]

As one can see from the chart below, normal vital signs vary with age. As the newborn (birth to 30 days) ages, respirations and pulse progressively get slower while systolic blood pressure becomes higher. Physiologically, these changes are associated with body surface area to weight. This ratio is seen in nature where smaller animals tend […]

Hypovolemic Shock Hypovolemic shock, the most common type, is caused by insufficient circulating volume, typically from hemorrhage although severe vomiting and diarrhea are also potential causes. Hypovolemic shock is graded on a four-point scale depending on the severity of symptoms and level of blood loss. Typical symptoms include a rapid, weak pulse due to decreased […]

Lowered blood pressure delivers less oxygen to the body’s cells. When the cell experiences decreased oxygen levels in the blood, the cells resorts to plan B, anaerobic metabolism. All cells in the body have the ability to exist without oxygen. Ordinarily, oxygen is used in the cell primarily it is needed to convert glucose to […]

When the patient experiences a drop in blood pressure due decreased cardiac output the body unleashes a host of compensatory mechanisms. Human beings are constantly moving and changing positions. Increased workload of the body requires a circulatory system that is dynamic enough to maintain blood pressure in all situations. Usually, these countermeasures ensure consistent and […]

Pathophysiology is the study of the disordered physiological processes that cause, result from, or are otherwise associated with a disease or injury. Pathology is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism. Pathology describes the abnormal […]
