Utility of central venous pressure measurement in renal transplantation: Is it evidence based?

Table 1 Factors affecting the measured central venous pressure reading[9]

Central venous blood volume	Venous return/cardiac output Total blood volume Regional vascular tone
Compliance of central compartment	Vascular tone Right ventricular compliance: Myocardial disease Pericardial disease Tamponade
Tricuspid valve disease	Stenosis Regurgitation
Cardiac rhythm	Junctional rhythm Atrial fibrillation Atrio-ventricular dissociation
Reference level of transducer	Positioning of patient
Intrathoracic pressure	Respiration Intermittent positive pressure ventilation Positive end-expiratory pressure Tension pneumothorax
