Kortokoff sounds tests for?
pulsating sounds heard through stethoscope when measuring BP
What are Kortokoff sounds?
Pulsating sounds heard through stethoscope when measuring BP
What does S1 represent in heart sounds?
1st heart sound, systolic, ‘lub’, closure of mitral and tricuspid valves
What does S2 represent in heart sounds?
2nd heart sound, closure of semilunar valves, ends of ventricular systole
What is a normal range for pulse oximetry?
95-100%
How does COPD affect pulse oximetry readings?
Normal might be lower
What can affect the accuracy of pulse oximetry readings?
- Nail polish
- Melanin
- Temperature (cold hands)
- Dehydration
What is considered a normal resting pulse rate?
60-100 bpm
What is the purpose of auscultation of the heart?
To listen to heart sounds at specific valve locations
What does S3 indicate?
Low-pitched, extra heart sound during diastole, associated with rapid ventricular filling, can be a sign of heart failure
What does S4 indicate?
Right before S1, increase resistance
What are the components of pulmonary observation?
- Symmetry in chest rise
- Tracheal shift
- Diaphragmatic excursion
- Speech quality
- Breath odor
- Accessory muscles
What does tracheal shift indicate?
Trachea shifts towards lower pleural pressure side; shifts away from pleural effusion, towards pneumonectomy
What is the purpose of mediating percussion?
Assesses the density of underlying organs
What does a ‘resonant’ sound indicate during percussion?
Heard over air-filled organs such as the lungs
What does a ‘dull’ sound indicate during percussion?
Heard over solid organs such as the liver
What is the normal diaphragm excursion range during inspiration?
3-5 cm
What is the purpose of the Pitting Edema scale?
To suspect circulatory issues such as heart failure, venous insufficiency, or DVT
What is the scoring for Pitting Edema?
- 1+ = immediate rebound (2mm)
- 2+ = slight delay in rebound (4mm)
- 3+ = >15 sec delay (6mm)
- 4+ = >30 sec delay (8mm)
What does a positive Stemmer sign indicate?
Inability to pinch skin, presence of lower extremity lymphedema
What does the Homans sign test assess? how do you test it?
Deep vein thrombosis (DVT)
- The gastrocnemius muscle is squeezed while the foot is dorsiflexed with force
- Limitations
- Not highly specific or sensitive for DVTs; high false positives and high false negatives
- DF pain can be due to muscle strains, cellulitis, or Baker’s cyst
What is the Dyspnea Scale used for? what are the grades? (mMRC)
Measures perceived shortness of breath or breathing difficulty
What is the normal respiratory rate for adults?
12-30 BPM
What are the three types of normal lung sounds?
- Bronchial
- Bronchovesicular
- Vesicular
