Difference between ATPS STPD and BTPS
ATPS and BTPS are measures for lungs ventilation; but ATPS hasto be converted to BTPS because it has the characteristics of the ambient and not the patient's so themost accuret measurement will be the BTPS . and STPD will never be used to describe gas exchange in the lungs
27
BMI
Body mass Index
28
BIA
Bioelectrical Impecdance Analysis It provides and estimate % ofbody fat by passing asumal electrical current through the body and measuring its impidance. less body fat tissue =better conductivity
29
Orbital
lower bony margin of eye socket
30
Tragion
Upper part of the ear
31
Vertex
most superior point on the Skull
32
Body Mass Index
Measurement used to determine if a person is in it's adequate weigh depending to their height
33
Lean Body Mass
It counts the man of all your organs but it don't count fat | total body weight - body fat weight
34
MAP
Mean Arterial Blood Pressure
35
Cardiac Output (CO)
Heart Rate × Stroke Volume
36
PP
Pulse Pressure
37
SBP
Systolic Blood Pressure
38
DBP
Diastolic Blood Pressure
39
02 Pulse
CO = HR × SV
40
TPR
Total Peripheral Resistance
41
MHR
Estimated Maximal Heart Rate
42
Ergometer
Instrument that measures the amount of mechanical
43
Cardiorespiratory System
Responsable for distributing blood to all the body, CO2 diffuses out of the blood and O2 into it,for this to occur heart and lungs have to make some adjustments when doing exercise
44
By what is arterial pressure determined ?
Balance betweenCO and peripheral resistence
45
Major contributor to Peripheral Resistance
Arterioles
46
What does Systollc Pressure reflects?
Cardiac Output
47
By what is Diastolic pressure determined ?
peripheral resistance
48
What happens during exercise to BP?
- CO increases and is greater than vasodilation - Diastolic and Systolic pressure increase - The filling time of the heact chambers reduced
49
Who contributes to the distribution of blood to the organs of the body ?
The Autonomic Nervous System
50
What increases heart rate ?
Sympathetic Nervous System
51
Which nerves supply the heart?
Parasympathetic Nervous System
52
Which name decreases the rate?
Vagus Nerve
53
Shortenings in ECG
- TP interval | - QT interval
