3.1 Respiratory Assessment Flashcards
Respiratory System
The stimulus to breathe includes
Hypercapnia - Increased CO2
Hypoxia - Decreased O2
Inspiration (Breathing In) - Creates negative pressure
Expiration (Breathing out) - Creates positive pressure
Review of Systems Cough (ROS)
Cough - When did it start? - How Often? - Hacking? - Dry Acute Cough - Lasts 2-3 Weeks Chronic Cough - More than 2 Months Timing of the cough is important. - Respiratory Illness cough is continuous - Work irritants cough is in the afternoon - Sinus issues cause coughing at night - Bronchial Cough (Smokers Cough) happens in the morning
Review of Systems (Sputum)
Color and consistency - White is Viral - Yellow/Green is Bacterial - Pink and Frothy is indictive of Pulmonary Edema Bloody (Hemoptysis) - May indicate tuberculosis
Review of Systems (SOB)
What brings it on? How long does it last? What time of day does it occur? Noticeable Cyanosis? How many pillows do you sleep with? Orthopnea: SOB when supine
Review of Systems (Other Issues)
Chest Pain? Muscle Soreness from coughing? History of smoking? Flu/PNA Vaccines? Screened for TB?
Respiratory System Physical Inspection
- Begin inspecting the Thorax
- Anything you inspect Anterior you must also inspect Posterior
Inspect Thoracic cage shape, configuration, and color
- Anteroposterior (AP) diameter should be less than Transverse diameter roughly 1:2
- Skeletal deformities can limit Thoracic Cage Excursion (How much it expands and closes)
Barrell Chest - AP diameter equals Transverse Diameter
Chest looks like it is in constant inspiration. Common in COPD Patients.
Respiratory System Physical Assessment
Skeletal Deformities
Kyphosis - Outward curve of spine “Hunchback”
Scoliosis - Sideways curve of spine
- Patient facial expression indicates unconscious breathing patterns.
- Lips and nail bed should be free of cyanosis. Nails should not be clubbing (hypoxia)
Respiratory System Palpation
- Palpate chest over lung fields. Note lumps lesions and temperature
- Assess chest expansion by placing hands on posterolateral chest wall with thumbs at T9 and T10 vertebrae
Ask patient to take a deep breath, thumbs should move symmetrically.
Atelectasis, Pneumonia, Pleural Effusion - Unequal Expansion
Respiratory System Palpation
Pain when palpating could mean Pleural Inflammation
99 Test - Test Tactile Fremitus (Vibration)
- Place ulnar side of palm over lung fields and have patient repeat 99 noting vibration of palm
- Decreased Fremitus (vibration) may suggest obstruction or thickening, increased fremitus may mean consolidation (air that fills small airways is replaced with something else) (pneumonia).
Respiratory System Palpation
- Assess for Crepitus (crackling) with light palpations
ABNORMAL - Coarse Crackling felt over skin caused by air escaping from lungs into subcutaneous tissue. Common with COPD and Emphysema.
Respiratory System Percussion
Resonance - Low pitch, clear, hollow sound over lung tissue.
Hyperresonance - Lower pitched booming sound. Too much air (emphysema, pneumothorax).
Dull - Soft and muffled thuds signals abnormal densities. (Pneumonia, pleural effusion, atelectasis)
Respiratory System Percussion
Percuss borders of lungs (resonance)
Percuss abdominal viscera (tympani)
Space between the 2 sounds is the diaphragm, which should be 3-5 cm.
- Resonance can sound duller in obese or muscular people.
Auscultation of Respiratory System
- When listening, stand behind patient on posterior side of apices (top of lung) at c7 vertebra to base around t10 vertebra. Then from axilla down to 7-8th rib.
- Press hard enough with stethoscope to make imprint.
- Patient should take deep breath at each side
Normal Sounds for Respiratory System
Bronchial - Heard on anterior side, high pitched, loud, prominent during expiration. Harsh and hollow.
Vesicular - Low-pitched, soft, heard more during inspiration. “Rustling winds through trees”
Bronchovesicular - Moderate pitch and amplitude, heard equally in inspiration and expiration.
Abnormal Sounds
- Decreased or absent sounds maybe obstruction, mucus plug, loss of elasticity (emphysema), pleural thickening, and presence of fluid.
