Measure Normal values
PH- hydrogen ion concentration 7.35- 7.45
normal= fully compensated
PaCo2- partial pressure of
Carbon dioxide
35-45 mmHg
<35- hyperventilation
>45- hypoventilation
PaO2- partial pressure of
oxygen
80-100 mmHg
<80- hypoxemia
<60- hypoxic
type 1- low O2
type 2- low O2 and high Co2
HC03- bicarbonate
concentration
22-26/28 mmol/l
BE- base excess -3,+3
SaO2/SpO2- oxygen
haemoglobin (HB) saturation
(alternative- oximeter)
95/97- 100%
nocturnal O2- <88%
restriction/obstruction disease-
90% may be normal
SaO2 to PaO2 conversion 90%- 60%
80%- 50 %
70%- 40%
60%- 30%
40%- 20%
FiO2- fraction of inspired O2 0.21- room air
Heart rate Resting- 60-100 beats per min
Exercise-
Tachycardia- >100
Brachycranic- < 60
Blood pressure- systolic/
diastolic
120/80
pre-hypertension- >120-80
stage 1 hypertension- >140-90
stage 2 hypertension- >160-100
hypotension - <90-60
Temperature 36.5-37.5 degrees Celsius
> febrile
38 degrees= fever
Haemoglobin levels (HB) Female- 11.5- 15.5 g/100mls
Male- 14-18
FEV1- Forced expired volume in
1 sec
80-120% of predicted
sig improvement- >12-18% 15
min post bronchodilators
FVC- Forced vital capacity- total
amount of air that can be
expired
80-120% of predicted
FEV1/FVC- percentage of FVC in
the first second
>70% of total amount of air
expired in first second
<75% mild
