Week 1 lab Flashcards
pulse paradoxus
a >10 mmHg decrease in pulse pressure with each inhale
what causes pulse paradoxus
acute obstructive pulmonary disease
asthma exacerbation
pulse alterans
alternating between weak and strong heart beats
what causes pulse alterans
left-sided heart disease
hypotension mmHG
<90 systolic
mean arterial pressure <65
40 below person’s baseline
how to calculate mean arterial pressure
DP + 1/3(SP-DP)
SCM o/i
o - upper anterior manubrium / medial third of clavicle
i - mastoid process
pectoralis o/i
o - 2-6 costal cartilage/ribs, sternum, medial half of clavicle
i - lateral lip of intertubercular groove of humerus
serratus anterior o/i
o - upper 8 ribs
i - anterior surface of the vertebral border of scapula
latissimus dorsi o/i
o - lumbar aponeurosis from T6 and iliac crest
i - intertubercular groove of humerus
importance of T9 level
xiphisternal angle in midsternal
anterior axillary line runs from
anterior axillary fold through ASIS
posterior axillary line runs through the
posterior axillary fold
- lat and teres major
what connects at the xiphisternal joint
5th rib
what forms the triangle of auscultation
lateral border of trapezius
medial border of scapula
upper border of lat
where is the right lung hilum
T5 level
where is the left lung hilum
T6
cardiac notch location
2.5 cm from sternum at 5th ICS
fissure of left lung
oblique - upper and lower lobes
transverse fissure of Rt Lung, anterior to posterior location
anterior = 4th ICS
posterior = 5th ICS / midaxillary
left oblique fissure location from anterior
anterior - 6th costochondral junction
posterior - T 3/4
borders of heart
right atria - right 3rd CC
left atria - left 2nd CC
apex - 5th ICS midclavicular
right ventricle - right 6th CC
