A&P Review and Diagnostic Studies Flashcards
Learn basics to anatomy and pathophysiology of respiratory
What are the upper airway of the respiratory system?
Nose
Paranasal Sinuses
Pharynx
Larynx
what are the lower airway in the respiratory system?
Trachea Lungs Bronchi Bronchioles Alveoli
What is the pleura?
Surface area of lungs
what are the types of pleura?
Parietal
Visceral
what does the parietal pleura do?
lines thoracic pleura cavity
What does the visceral pleura do?
covers the lung surface and fissures between lungs
what does the pleurisy pleura do?
parietal and visceral pleura rub together (pleural friction rub)
What is determined by the size of the airway through which air is flowing?
Airway Resistance
what are some conditions that increase airway resistance?
- Contraction of bronchial smooth muscle
- Thickening of bronchial mucosa
- airway obstruction
- loss of elasticity
what is tidal volume (TV)?
volume of air with each inspiration
what is residual volume or reserve volume (RV)?
volume of air remaining in lungs at end of maximum expiration
what is vital capacity (VC)?
volume of air that can be expelled after maximum inspiration
what is inspiratory capacity (IC)?
maximum volume of air inhaled after normal expiration
what is forced expiratory volume (FEV)?
volume of air expelled within first second of vital capacity
what is peak expiratory flow rate (PEFR)?
measures large airway function in liters/min
what is total lung capacity (TLC)?
volume of air in lungs after maximum inspiration
What is the normal pH?
7.35 - 7.45
A noninvasive test that measure oxygen saturation of Hgb. SaO2/SpO2
Pulse Oximetry
what is the normal range for PCO2?
35-45 mm Hg
what is the normal range for PO2?
80-100 mm Hg
what is the normal range for HCO3?
22-26 mEq/L
what is the normal range for O2 Saturation?
> 94%
What is used in the diagnosing of TB?
Sputum Cytology
when is the best time to collect sputum culture?
Before Breakfast
Is sputum cytology a sterile procedure?
yes, the container must remain sterile, the top edge must not be touched nor the inside.

Bronchoscopy
What is the pre-procedure for a bronchoscopy?
- must sign consent. Sedated for this
- NPO (4-6 hours)
- remove dentures if applicable
- usually hold anti-coagulants
what is the post-procedure for bronchoscopy?
- NPO until gag reflex returns
- may use warm gargles post procedure
- assess for bleeding
- Post-op assess
- Assess respiratory status
