pulse, respiration and bp
Question | Answer |
---|---|
Temporial Artery | Located on the temple directory in front of the ear. |
Carotid Artery | Runs along both sides of your neck. Used for pulse in patients who are in shock or lack of a detectable pulse |
Apex of Heart | Not an artery, apical pulse site below the heart. |
Brachial Artery | Inside the upper arm near the elbow. |
Radial Artery | Located laterial of the wrist. |
Femoral Artery | Located inner thigh at mid ing point. |
Dorsalis pedis | Top of the foot. |
Popliteral Artery | Behind the knee. |
Describe the characteristics of pulse | Rate - S/B 60-100 bpm normal range at rest. Rhythm - Regular / irregular. If irregular retake for 60 sec. Volume - if strong bounding)or weak (thready). |
Weak | 1+ |
Normal | 2+ |
Bounding | 3+ |
State normal range of heart rate and factors which influence each. | 60 - 100 Factors which influence, stress, medication, exercise. |
Bradycardia | < 60 |
Tachycardia | > 100 |
Define the difference between heart rate and pulse. | HR is how many beats per minute. Pulse vibration agaist the wall. |
Define pulse deficit | Numerical differnece between apical pulse and radial pulse. I.E. apical 101, radial 88 pulse deficit would be 13 bpm. |
Describe procedure to take pulse. | Palm side of the patients wrist w/your first 3 finger tips approx. 1" below |
Define respiration; state factors which influence. | Inhalation & exhalation makes one count. Factors include excercise, lung disease and sleep apnea. |
Name the control center of pulse and respiration. | Medulla |
Describe pulse oximetry | A device usually attached to the earlobe or fingertip, that measures the oxygen saturation or arterial blood. Normal range 95 -100 % |
Describe respiratory physiology; role of phrenic nerve and diaphragm and O2 and CO2 levels. | Medulla receptors are sensitive to levels co2 and o2. Stimulate for stimulating. Phronic nerve travels to diaphragm - contract. CO2 up & o2 down stimulate for stimulating phronic nerve. |
Define blood pressure | Force excerted by blood against the arterial wall. |
Define cardiac output | amount of blood ejected from the heart per minute. If HR is higher blood output is higher |
Define peripheral resistance | opposing force of the vessel against the blood. Athersclerosis. |
Define stroke volume | amount of blood ejected from the heart per contraction. damage to heart |
Define pulse pressure | numerical difference between systolic bp and diastolic bp. |
List physiological factors which determine bp. | Blood volume Cardia output stroke volume peripheral resistance homones |
Systolic normal range | 80 - 140 |
Diastolic normal range | 0 - 79 |
Severe hemorrhaging would | decrease blood pressure and increase pulse. |
What hormones increase BP | ADH (anti-directic retains water)and Aldosterone (retains salt) |
What is BP measured in | Millimeters of mercury each line represents 2 |
What method is used in obtaining a BP using the sethoscope auscultatory or palpatory? | auscultatory |
List what is meant by vital signs | Body temperature, blood pressure, pulse and respiration rate. |
Define arteriosclerosis | Harding thickening and loss of elasticity of the arterial wall. |
Atherosclerosis | Narrowing of the arterial lumen. fatty plaques. |
What are the 5 phases of BP | I. 1st sound systolic II. sounds continue (swish auscltatory gap) III. sounds continue (if swish could be mistaken for systolic. IV. korothkoff sounds stop diasytolic V no sounds |
List 7 factors that could cause a an error in a BP reading. | 1. Legs crosssed, cuff applied over clothing, drank coffee or smoked within 30 minutes of test, bladder is not centered, cuff is too large, limb is not elevated with heart. |
