Cardio Pulm
Normal/Abnormal Responses
| Question | Answer |
|---|---|
| What is the normal HR range? | 60-100 bpm |
| Generally, what is the formula for max HR? | 220-age |
| A HR below __ is considered abnormal. | 40 bpm |
| CO is typically between how many L/min | 4-6 L/min |
| A low HR can be a sign of what? | blockage |
| Resting HR above __ bpm may be abnormal. | 100 |
| A pt that presents with the following may have what? Low Resting HR (50 – 70 bpm) Poor physical condition (untrained) Advanced 3-vessel disease Max HR limited by symptoms well below PMHR Males between ages of 40 – 60 | CAD |
| If ones HR falls with increasing work load, what should you do? What could this be a sign of? | STOP EXERCISE/CAD |
| What are the normal responses to exercise for the following? CO, Systolic BP, diastolic BP | CO increases, systolic rises as workload increases, diastolic may increase, remain, or drop slightly |
| Well conditioned athletes may experience a _____ ______ in diastolic pressure when exercising. | sharp drop |
| With increasing workloads, are responses of both systolic and diastolic BP normal or abnormal? What can this be a sign of? | abnormal/pathology |
| Is a flat systolic response response to increasing workloads normal or abnormal? | abnormal |
| Systolic begins low (110 mmHg) rises slightly, then begins to fall despite increased HR and workload...what might this be a sign of? | post infarction |
| A drop in systolic BP w/ exercise is considered significant at what level? | > 10mmHg and/or clinical signs such as SOB, development of 3rd heart sound |
| T or F. A drop in SBP w/o other abnormalities is OK. | True...A flat or fall in systolic BP in middle-age women, or pts on beta-blockers not significant unless accompanied by other abnormalities. |
| Abnormal SBP response associated with SOB, ST depression or elevation, agina or pallor, 3rd heart sound could be signs of what? | severe ischemia, poor ventricular function, or combination |
| Is a persistent rise in diastolic pressure w/increased exercise workload normal or abnormal? What might this be a sign of? | abnormal/increases severity of CAD |
| Diastolic Blood Pressure Abnormalities are defined as diastolic rise of __ mm Hg above __ mm Hg with increasing levels of exercise | 20, 90 |
| Chest discomfort caused by impaired blood supply to cardiac muscle is called what? | Angina |
| What is the measurable point at which angina may occur and what is this formula? | Rate Pressure Product(RPP), HRxSBP |
| Angina that recurs at a fixed RPP, is reproducible by eating, emotional distress, or exercise and is relieved by rest or nitroglycerin is what kind of angina? | Chronic Stable Angina |
| What kind of angina is caused by vasospasm of the coronary artery? | variant angina |
| What is another name for variant angina? | Prinzmetal angina |
| What king of angina occurs at rest or may wake a patient at night? | Unstable angina |
| Which type of angina is also called "preinfarction" angina? Why? | unstable angina. It is an ominous symptom of impending MI. |
| Does chronic stable angina occur at lower or higher RPP's than unstable angina? | usually lower |
| How many levels are used to rate angina? | 4 |
| What level of angina?....the initial perception of discomfort. Reflects a minimum level of discomfort. | Level I |
| What level of angina?....initial discomfort has intensified over the same or relatively the same body surface area, or it has become referred discomfort that extends to another body surface area. | Level II |
| What level of angina?....initial discomfort has become so severe that the pt stops whatever they are doing as seeks medicinal relief. | Level III |
| What level of angina?....same severity of discomfort that the patient feels during a heart attack | Level IV |
