Blood Pressure Measurement | Best Positions | Cardinal Techniques | Landmarks | ECG |
---|---|---|---|---|
The elbow is slightly flexed with the brachial artery at the level of the heart.
The correct position of the arm when taking the blood pressure
|
sitting
thorax & lungs
|
palpation
joint crepitus
|
sternal angle/ angle of Louis
best guide for counting the ribs & interspaces
|
4th ICS to the right of the sternum
lead placement of V1
|
~ 2.5 cm above the antecubital fossa
The proper placement of the cuff
|
supine with head of bed raised 30 degrees
cardiovascular system (JVP, PMI, murmurs)
|
auscultation
valvular pathology
|
5th ICS just medial to the left mid clavicular line or 7-9 cm from the sternal line
location of the point of maximal impulse (PMI)
|
midaxillary line same level as V4 & V5
lead placement of V6
|
Pevent discomfort from unnecessarily high cuff pressure
Rationale for estimating the systolic BP by palpation method before actual BP measurement
|
left lateral decubitus
rectal exam & prostate
|
inspection
respiratory distress
|
at or near the lower left sternal border
murmurs originating from the tricuspid valves
|
1 mv (10 mm) & 25mm/sec
standard voltage and speed
|
auscultatory gap
a silent interval that may be present between systolic and diastolic pressures
|
dorsal lithotomy
pelvic & rectal exam
|
percussion
dullness, resonance, or tympany
|
2nd interspace left
surface marker for the pulmonary artery
|
smooth like a hill
normal configuration of the p wave
|
"white coat" hypertension
a condition wherein the office BP is high but the ambulatory pressures are normal
|
sitting, leaning forward
murmur of aortic insufficiency
|
auscultation
distinguish pleural fluid from mass in lungs
|
The inferior angle of the scapula lies at the level of the 7th rib. The interspace T7-T8 is a landmark for thoracentesis.
a useful bony landmark in the posterior thorax
|
normal, but if prominent assoociated with T wave changes it may indicate hypokalemia
significance of the presence of p wave
