When above the phlebostatic axis, reported values will be lower than actual when below the phlebostatic axis, reported values will be higher than actual. Incorrect leveling is the primary source of error in direct pressure measurement with each inch the transducer is misleveled causing a 1.86 mmHg measurement error. Note that the mid-axillary line is often not at mid-chest level in patients with kyphosis or COPD, and therefore should not be used as a landmark. This location, referred to as the phlebostatic axis, is located at the intersection of the fourth intercostal space and mid-chest level (halfway between the anterior and posterior chest surfaces. In seated patients, be certain to leave the arm at the patientвЂ™s side.ДЄrterial pressure transducers are subject to similar inaccuracies when the transducer is not positioned at mid-heart level. To correctly assess BP in a side lying patient, hold the BP cuff extremity at mid heart level while taking the pressure. Patients lying on their side, or in other positions, can pose problems for accurate pressure measurement. Errors can be significant - typically 2 mmHg for each inch the extremity is above or below heart level.ДЄ seated upright position provides the most accurate blood pressure, as long as the arm in which the pressure is taken remains at the patientвЂ™s side. Measuring BP in an extremity positioned above heart level will provide a falsely low BP whereas falsely high readings will be obtained whenever a limb is positioned below heart level. When using a cuff, the arm (or leg) where the cuff is applied must be at mid-heart level. The standard reference level for measurement of blood pressure by any technique -В direct or indirect -В is at the level of the heart. To accurately assess blood flow in an extremity, influences of gravity must be eliminated. The second most common error in BP measurement is incorrect limb position. YouвЂ™ve incorrectly positioned your patientвЂ™s body In their 1981 guidelines, the diastolic BP recommendation changed to the start of phase V. In their 1967 guidelines, the AHA recommended that clinicians record the systolic BP at the start of phase I and the diastolic BP at start of phase IV Korotkoff sounds. IV вЂ“ pitch intensity changes and sounds become muffled.III вЂ“ change in sounds to a thumping quality (loudest).II вЂ“ sounds become softer, longer and may occasionally transiently disappear.I вЂ“ first detectable sounds, corresponding to appearance of a palpable pulse.Korotkoff sounds are the noises heard through a stethoscope during cuff deflation.

Multiple smaller sizes are needed if you frequently treat pediatric patients.

Carrying at least three cuff sizes (large adult, regular adult, and pediatric) will fit the majority of the adult population. The most practical way to quickly and properly size a BP cuff is to pick a cuff that covers two-thirds of the distance between your patientвЂ™s elbow and shoulder. Most practitioners find measuring bladder and arm circumference to be overly time consuming, so they donвЂ™t do it. recommending that the bladder length and width (the inflatable portion of the cuff) should be 80 percent and 40 percent respectively, of arm circumference. The American Heart AssociationВ publishes guidelines for blood pressure measurementВ . A BP cuff that is too large will give falsely low readings, while an overly small cuff will provide readings that are falsely high. The most common error when using indirect blood pressure measuring equipment is using an incorrectly sized cuff.
