20
Q

PaO2

A

98-100mmHg

21
Q

Oxygen Partial Pressure values highest to lowest to know:

A

PatmosO2: 159mmHg
PAO2: alveolar: 103mmHg
PaO2: arterial: 98%
PO2: mean capillary: 40mmHg
Myoglobin: 2-3

22
Q

Oxyhemoglobin

A

Binding of O2 to hemoglobin
-hemoglobin contains iron which binds to O2

23
Q

100% saturation is when:

A

O2 bound to hemoglobin equals the O2 carrying capacity of hemoglobin
Usually never 100%, usually about 97-98%

24
Q

Oxyhemoglobin Curve is:

A

S-shaped, sigmoidal
-usually near complete saturation of PO2 at 60mmHg and higher

25
Q

Higher partial pressure allows for:

A

More O2 carrying capacity

26
Q

Arterial blood PAO2 is at

A

98-100 mmHg
-almost complete saturation

27
Q

Capillary- tissue (muscle) PO2 is:

A

40mmHg
-causes dissasociation of O2 from hemoglobin, allowing O2 to be available for muscle

28
Q

Carbon Dioxide Transport in the Blood

A

Around 5% transported in plasma
60-80% of total CO2 transports in combo with water as bicarbonate -binds with H+ to form carbonic acid which splits into CO2 and H2O in lungs
20% bound with hemoglobin

29
Q

Vi or VE

A

Minute ventilation
-amount of all air breathed in 1 minute (L/min or ml/min)
VE= VT (tidal volume) x F (frequency)

30
Q

VA

A

Alveolar ventilation
-amount of air available for gas exchange
VA= (VT (tidal) - dead space) x F (frequency)

31
Q

Partial pressure of O2

A

159mmHg
-under conditions of normal atmospheric pressure

32
Q

PAO2

A

Alveolar partial pressure
103mmHg

33
Q

PaO2

A

Arterial Partial Pressure
98-100mmHg

34
Q

PO2

A

Muscle partial pressure
40mmHg

35
Q

PO2

A

Muscle partial pressure
40mmHg

36
Q

Oxyhemoglobin disassociation curve

A

97-98% saturated at most
>60mmHg = almost complete saturation
<60mmHg= increased disassociation =release of O2
