Pulmonary Assessment of the Pulmonary System Flashcards
(35 cards)
Cough
- irritation of the pulmonary system
- most frequent sign of pulmonary disease
- stimulus anywhere from upper to lower airway
Hemoptysis
Sputum containing blood, old (clots) or new (pink or red streaks)
Dyspnea
difficulty breathing - a conscious effort
- shortness of breath
paroxysmal nocturnal dyspnea
in the middle of the night, the shortness of breath comes- (symptoms come and go)
Pulmonary edema
accumulation of fluid in the alveoli in the lungs
- makes it harder for gas molecules to pass across,
- drowning to death from bot being able to breath in and breath out efficiently
ARDS
Acute respiratory destress syndrome
- patients can no longer sufficiently oxygenate themselves
- often need ECMO
Chest Xray
different tissues in our body absorb X rays at different intensities
- air (least opaque) –> bone/metal (most opaque, white)
5 densities (air, fat, soft tissue, bone, metal)
The 6 P’s of Dyspnea:
- Pulmonary Bronchial Constriction
- Pulmonary embolus
- possible foreign body
- pneumothorax
- pump failure
- pneumonia
Chest pain unrelated to heart problems
Retrosternal pain
Pleural pain
Musculoskeletal pain
Physiological sighs of pulmonary disease
- hypoxia (reduction of oxygen in tissues)
- hypoxemia ( reduction of oxygen in blood supply)
- acute hypercarbia/hypercapnia - produce or “altered” mental state
Hypoxemia
oxygen supply to the tissue is below physiologic levels
Hypoxemia signs:
- Tachycardia:
- Tachypnea:
- Arrythmias:
- Dyspnea:
- faster than normal heart rate (>100bpm)
- Rapid breathing (>20 bpm)
- Heart rate irregularity
- difficult or labored breathing
Normal Respiratory rate
10-18 per minute
Cyanosis
diffuse, bluish discoloration of the skin and mucous membranes
- (central and peripheral cyanosis)
- appears first in nail beds, mucous membranes, anise and earlobes
generalized edema
fluid (stuck in interstitial space) accumulation in the whole body
- renal, hepatic, endocrine, metabolic, and cardiac diseases
- Cor pulmonate: enlargement of RV secondary to pulmonary disease
High capillary pressures force plasma water into body tissue
- increased venous pressure
Posturing
allows patient to stabilize shoulders
- enlist accessory muscles too augment effort
- increases tidal volume
Percussion
Technique that determines the density or consistency of lung by evaluating sounds from tapping the chest wall
Auscultation
Listen for sounds of air flow through tracheobronchial tree
Pulmonary Function testing (PFT)
generic term to indicate multiple studies performed to evaluate the respiratory system and pulmonary function
- gives insight into underlying pathophysiology by comparing measured values
- percentage of predicted normal issued to grade the severity of the abnormality
Purpose of PFT
to determine how much air volume can be moved in and out of lungs and how fast
Contraindictions
- PFT is done on every patient before surgery unless:
- hemoptysis of unknown origin
- pneumothrorax
- unstable cardiovascular status
- thoracic, abdominal or cerebral aneurysm
- eye surgery
- recent MI
- Acute Respiratory infection
Equipment: Spirometer
designed to measure changes in volume and can measure lung volume compartments that exchange gas with the atmosphere
PFT test considerations:
- age
- gender
- body habitus
- race
FVC- Forced vital capacity
after patient has taken the deepest possible breath, this is the volume of air which can be forcibly and maximally exhaled out of the lungs until no more can be expired
