A
ASV
Adaptive Support Ventilation
Available on Hamilton(TM) ventilators
Asynchrony Index
Total asynchrony events / total breaths * 100
BAL
Broncho-Alveolar Lavage
BMR
Basic metabolic rate
CMV
Conventional Mechanical Ventilation
CPAP
Continuous Positive Airway Pressure
CXR
Chest X-Ray
Cl-
Chloride
Cycling
Terminating a breath
DO2
Oxygen Delivery
DO2 = CO x SaO2 x Hb + (paO2 x 0.03)
EELV
End-Expiratory Lung Volume
ETT
Endotracheal Tube
F
FEV1
Forced Expiratory Volume in the first second
FiO2
Fraction of Inspired Oxygen
H
HFOV
High Frequency Oscillatory Ventilation
Hb
Hemoglobin
I
IC
Inspiratory Capacity
IPPV
Intermittent Positive Pressure Ventilation
IRV
Inspiratory Reserve Volume
K
L
LV
Left Ventricle
LVOT
Left Ventricular Outflow Tract
MAP
Mean Airway Pressure = Area under the pressure curve
Na+
Sodium. Dialy requirement 3-4mmol/kg
OI
Oxygenation Index = (MAPxFiO2)/paO2
P
P-SILI
Patient Induced Self-Inflicted Lung Injury
PC
Pressure Control
PEEPi
Intrinsic PEEP = Auto-PEEP
PRP
Pressure Rate Product = PRP = pressure x respiratory rate
PTP
Pressure Time Product = PTP = Pavg × Ti = Average pressure during inspiration x Inspiratory time
Palv
Alveolar Pressure
Paw
Airway Pressure
Pcw
Trans Chestwall pressure
Q
Qp/Qs
Pulmonary to systemic perfusion ratio.
Qp/Qs = (SaO2 - ScvO2) / SpvO2 - SpaO2)
R
Resistance [cmH2O/l/sec]
R=U/I
RM
Recruitment Manouvre
RR
Respiratory Rate
RV
Right Ventricle
Reverse Triggering Index
Total reverse triggering events / total breaths * 100
S/T
Spontaneous / Timed Mode
SIMV
Synchronised Intermittent Mandatory Ventilation
SaO2
Arterial Oxygen Saturation
Shunt
Perfused but not ventilated part of the lung in which V is 0 and P is present. V/Q Ratio is therefore 0.
Stress
Equivalent to Transpulmonary Pressure
T
