CVP-MAL: central venous pressure (CVP) measured from the midaxillary line (MAL) at the fourth intercostal space; CVP-MTP: CVP measured from the midthoracic plane (MTP) at the anterior fourth intercostal space level; JVP-MTP: jugular venous pressure (JVP) measured from the MTP; JVP-SA + 5: JVP measured from the sternal angle (SA) with the addition of 5 cm.
