| What is ausultation? | listening to the chest with a stethoscope placed over the heart |
| How are apical pulses obtained? | listening to the heart with a stethoscope placed over the chest and counting each heartbeat |
| -reflect the rapidity of each heart contraction and are recorded as the number of beats/min | pulse rates |
| How are arterial oxygen saturation levels measured> | though a periodic blood-gas analyses |
| -catheter that is inserted into an artery | arterial line |
| -nonivasive device used to provide ongoing assessment of the hemoglobin oxygen saturation of arterial blood as well as the patient's pulse rate | pulse oximeter |
| How are hemoglobin oxygen saturation and pulse rate determined? | by measuring absorption of selected wavelengths of light by the circulating blood |
| What is the normal pulse oximeter value for a healthy person? | 95%-100% |
| -when heart contractions & pulse rates increase by more than 20 BPM in the resting adult or reach a rate greater than 100 BPM | tachycardia |
| -decrease in heart rate | bradycardia |
| -measure of the force exerted by blood on the arterial walls during contraction and relaxation of the heart | blood pressure |
| -the pressure that is exerted on the arterial vessels by the blood when relaxed | diastolic |
| peak pressure present during contraction of the heart is... | systolic |
| -the persistent elevation of blood pressure above 140/90 | hypertension |
