Harman Hints test #1 old fucks Flashcards
what is the main CV change r/t aging** ( 1 main concept to remember)
the general response is a decreasing response to stimulation of the ANS
Can the old heart compensate for stress?
nope
What happens to the cardiac reserve in the old fart?
reduced
what happens to CO in the old foggie?
decreases
what happens to the HR in old farts?
decreases
what happens to conduction time in the older population?
slows
* decreased CO and HR lead to what?*
Increased circulation time
what happens to Systolic BP in elderly
Increase
what can happen to diastolic BP with age
may actually fall ( decrease)
7 common Age related renal/hepatic changes
- DECREASED renal blood flow
- DECREASED urine concentrating ability
- DECREASED ability to conserve H2O
- DECREASED elimination of drugs
- DECREASED hepatic blood flow
- DECREASED plasma drug clearance
** all DECREASED
6 common age related CNS A&P changes
-DECREASED activity
- DECREASED O2 consumption
-REDUCED # of functioning receptors
- REDUCED production of NT
- Neuron loss
- DECREASED CBF
All decreased
8 common pulmonary age related A&P changes
- INCREASED lung compliance
- DECREASED forced expiratory volume
- INCREASED closing volumes
- DECREASED resting arterial O2 tension
- INCREASED alveolar-arterial differences
- V/Q mismatch
- DECREASING FRC
- DECREASING TLC
11 Common age related CV A&P changes
- impaired pump fxn
- prolonged circulation time
- myocardial fiber atrophy
- HTN
- Impaired cardiac adrenergic receptor quality
- Increased PVR
- DECREASED CO
- DECREASED organ fxn
- DECREASED organ perfusion

- CAD
7 common age related A&P changes??
DECREASED organ function -INCREASED body fat - DECREASED blood volume - DECREASED ability to retain heat - DECREASED in lean body mass -DECREASED skin elasticity - collagen loss - DECREASED intracellular water the only thing that increases is FAT
* if a question on the test ask about organs the answer is generally what??
DECREASED
