Document Summary
Nse 13a- assessment of healthy individual: week 5 objectives. Jarvis chapter 10: define pulse respirations, and blood pressure and their normal limits. Pulse respirations is the cycle that consists of inspirations and expirations (counted as 1) Do not mention to the patient that you are counting respirations (will alter number) Maintain you position of counting the radial pulse and unobtrusively count the respirations (30 seconds -1 min) Cardiac output heart pumps more blood, pressure on vessel walls goes up. Peripheral vascular resistance the opposition to blood flow through the arteries (blood vessels get smaller, greater pressure needed to push through) Volume of circulating blood how tightly the blood is packed into the arteries (blood increases, pressure increases) Elasticity of vessel walls when vessel walls are stiff and rigid, more pressure needed: describe the relationships among the terms blood pressure, systolic pressure, diastolic pressure and pulse pressure. Systolic pressure maximum pressure felt on the artery during left ventricular contraction.
