Oxygenation, ventilation, flow
Percent of carbon dioxide in the atmosphere
.03 percent
Percent of argon in the atmosphere
.9 percent
Respiratory rate
12-20 BPM
blood pressure
120/80
Percent of oxygen in the atmosphere
21 percent
Normal level of CO (carbon monoxide) in the body
3 percent for non smoking adults 3-10 percent for smoking adults
Heart rate
60-100 bpm
Percent of nitrogen in the atmosphere
78 percent
temperature
98.6 F 37 C
Compliance (Cst) (Cdy)
Ability of lung to accept volume change per unit of pressure applied
ABG
Arterial blood gas, measured pH, oxygen content, and Co2 content in the arterial blood. Normal values: 7.4 pH - 40 mmHg PaCO2 - 100 mmHg PaO2 - 24mmHg bicarbonate
FiO2
Fraction of inspired oxygen
SVO2
Measure of oxygen on the venous (returning) side, normally 75%
SPO2
Measures oxygenation by measuring the percent of hemoglobin saturated with oxygen in the blood
P:F Ratio
PaO2/FiO2 100/.21 = 476 = normal/healthy ratio Used to diagnose ARDS
PaCO2
Partial pressure of CO2 in the arterial blood. Used to measure ventilation
PaO2
Partial pressure of oxygen in the arterial blood = 100 mmHg
PAO2
Partial pressure of oxygen in the atmosphere = 159 mmHg
P:F less than 300
Patient has ARDS
Peak inspiratory pressure (PIP)
Pressure required for ventilator to go through circuit to deliver gas to the lungs
Plateau pressure (Pplat)
Pressure required to ventilate distal airways and alveoli
Hemoglobin
Red blood cells carry Hbg, Hbg carry 4 O2 molecules males: 12-18 g/dl females: 10-16 g/dl
2-3 DPG
Tells hemoglobin to either release or hold onto O2 depending on shift in the curve. Increase 2-3 DPG = release O2 (right shift) Decrease 2-3 DPG = hold onto O2 (left shift)
Elastance
ability of lung to retain or go back to original shape after being stretched
Kussmals
fast and deep breathing
Biots
fast and deep with apnic periods
Airway resistance (Raw)
impedance to flow, affected by diameter, length, and obstruction
High SPO2 and high SVO2
indication that cells are not taking up much oxygen, a way to measure if patient is hypoxic
hypoxic
lack of oxygen at the cellular level
hypoxemic
low O2 saturation and percent of O2 in the blood
hypothermia
low body temperature, protective state for the body
Afibrile
no fever present
asystonic
no heart rate
apnea
not breathing
Cheyanne stokes
short, slow breaths building up to fast and deep breaths with apnic periods
hypertenisve
systolic pressure greater than 140
hypotensive
systolic pressure less than 90
