day 3 health

• VITAL SIGNS - Hands on physical examination begins
• BLOOD PRESSURE - The force of blood exerted on the wall of the arteries when the left ventricle of the heart pushes blood into the aorta
• SYSTOLIC PRESSURE - Maximum pressure on the arteries during left ventricular contraction
• DIASTOLIC PRESSURE - The resting pressure of the arteries between each cardiac contraction
• PULSE PRESSURE - Represents max and minimal circulatory pressure during cardiac cycle
• MEAN ARTERIAL PRESSURE - The average pressure over a cardiac cycle, systole and diastole
• ANEROID - Circular gauge for registering pressure
• MERCURY SPHYGMOMANOMETER - Medical device for measuring blood pressure that uses mercury
• DIGITAL SPHYGMOMANOMETER - Provides a digital readout of the blood pressure
• STETHOSCOPE - An acoustic medical device for auscultation or listening to the internal sounds of an animal or human body
• PHASE 1 - This is the first sound heard as the cuff pressure is released
• PHASE 2 - Swishing sounds as the blood flows through blood vessels as the cuff is deflated
• PHASE 3 - Intense thumping sounds that are softer than phase 1
• PHASE 4 - Softer and muffled sounds as the cuff pressure is released
• PHASE 5 - Silence that occurs when the cuff pressure is released enough to allow normal blood flow
• RESPIRATION - Process by which oxygen and carbon dioxide are interchanged
• Ventilation - movement of gases in and out of the lungs
• Diffusion - exchange of gases from an area of higher pressure to an area of lower pressure
• Perfusion - availability of movement of blood for transport of gases, nutrients and metabolic waste products
• Diaphragmatic Breathing - contraction and relaxation of the diaphragm
• Costal Breathing – contraction of intercostal muscles and other accessory muscles
• Cheyne Stokes Respirations – periods of very deep to very shallow breathing temporary apnea
• Biot’s – abnormal breathing pattern with groups/cluster of rapid respiration of equal depth and regular apnea
• Kussmaul’s – increased rate and increase depth
• PAIN - An unpleasant sensory and emotional experience which we primarily associated with tissue damage or describe in terms of such damage
• PAIN THRESHOLD - Amount if pain stimulation a person requires before the feeling of pain
• PAIN TOLERANCE - Maximum amount and duration of pain of anindividualiswilling to endure
• PAIN SENSATION - The actual feeling of pain
• BRADYKININ - Universal stimulus of pain
• HYPERALGESIA - Excessive sensitivity to pain
• SOMATOSENSORY CORTEX - identifies the location and intensity of pain
• ASSOCIATION CORTEX - determines how the person feels about it
