General Survey, Measurement, Vital Signs
What physical appearances are observed in a General Survey?
age, sex, level of consciousness, skin color, and facial features
What body structures are observed in a General Survey?
stature, nutrition, symmetry, posture, position, and body build/contour
What are the main characteristics observed in a general survey?
physical appearance, body structures, mobility, behavior
How can temperature be measured?
oral, electronic thermometer, axillary, rectal, and tympanic membrane thermometer
What are the factors that an influence temperature?
diurnal cycle, menstrual cycle, exercise, and age
In adults, at rest, the heart rate is less than 50 beats/min.
Rapid heart rate (at rest)- heart rate is over 95 beats/min or over 100 beats/min
What is sinus arrythmia?
the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration
define blood pressure
the force of the blood pushing against the side of its container, the vessel wall.
What is systolic pressure?
the maximum pressure felt on the artery during left ventricular contraction
What is diastolic pressure?
the elastic recoil or resttng, pressure that the blood exerts constatly between each contraction
What is pulse pressure?
the difference between the systolic and diastolic pressures and reflects the stroke volume
define mean arterial pressure (MAP)
the pressure forcing blood into the tissues averaged over the cardiac cycle
What factors that can influence blood pressure?
age, rage, weight, emotions, sex, diurnal rhythm, exercise, and stress
What are the physiologic factors controlling blood pressure
Cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of vessel walls
