Pulmonology for Medical Assistants

Vocabulary terms covering clinical pulmonology, diagnostic respiratory testing, nebulizer medications, and adventitious breath sounds for Medical Assistants.

Pulmonology

The medical study of the lungs and the respiratory system, derived from "pulmo" (meaning lungs) and "-ology" (meaning study of).

Effort-Dependent Test

A diagnostic assessment, such as spirometry or peak flow testing, where the validity and accuracy of the results rely entirely on the patient's maximum effort and technique, requiring active guidance and coaching from the Medical Assistant.

Chronic Obstructive Pulmonary Disease (COPD)

A chronic pulmonary disease characterized by long-term, progressive respiratory damage that is not fully reversible, contrasting with acute conditions like asthma flare-ups which are temporary and reversible.

Emphysema

A chronic lung disease marked by the permanent destruction and bursting of alveoli (air sacs), which causes them to lose their natural elasticity.

Small Volume Nebulizer (SVN)

A respiratory therapy device consisting of a compressor, tubing, medication cup, and mouthpiece or face mask that converts liquid medication into a fine mist for direct inhalation into the airways, typically finishing in $10$ to $15\,\text{minutes}$.

Albuterol Sulfate

A fast-acting inhaled bronchodilator that rapidly relaxes airway smooth muscle, frequently causing temporary adverse effects of tachycardia (elevated heart rate) and tremors or jitteriness due to beta-2 receptor stimulation.

DuoNeb

A combination medication administered via SVN that contains Ipratropium with Albuterol Sulfate to deliver dual-action bronchodilation.

Budesonide

An inhaled corticosteroid administered through a small volume nebulizer to reduce inflammation within the airways.

Xopenex (Levalbuterol)

An alternative SVN bronchodilator that produces airway relaxation with a lower incidence of jitteriness and tachycardia compared to albuterol.

Six Rights of Medication Administration

The core medication safety protocol verified prior to administration: Right Patient, Right Drug, Right Dose, Right Route, Right Time, and Right Documentation.

Spirometry

A diagnostic Pulmonary Function Test (PFT) that measures both the total volume of air a patient can exhale and the speed of exhalation, requiring upright posture, nose clips, a tight seal, and forceful exhalation for at least $6\,\text{seconds}$.

Peak Expiratory Flow Rate (PEFR)

A test measuring the maximum speed of exhalation using a peak flow meter, used primarily by asthma patients at home to monitor day-to-day airway constriction.

Personal Best (Peak Flow)

The highest peak flow measurement achieved when a patient's asthma is well-controlled and breathing is normal, which serves as the individual benchmark for their Asthma Action Plan.

Peak Flow Recording Protocol

The clinical standard requiring the patient to perform $3$ acceptable peak flow attempts, with the Medical Assistant documenting only the single highest value rather than the average.

Green Zone (Peak Flow)

A peak flow range of $80\%$ to $100\%$ of personal best; signals that breathing is fine with no attack signs and indicates the patient should maintain their daily baseline routine.

Yellow Zone (Peak Flow)

A peak flow range of $50\%$ to $80\%$ of personal best; signals that breathing is hampered, requiring the use of rescue medication and rechecking peak flow in $20$ to $30\,\text{minutes}$.

Red Zone (Peak Flow)

A peak flow reading below $50\%$ of personal best; constitutes a medical alert indicating labored breathing, requiring immediate quick-relief medication and contacting a doctor or calling 911.

Oxygen Saturation ($SpO_2$)

A measurement of the oxygen concentration in the blood, recorded via pulse oximeter sensors placed at the fingertip, earlobe, bridge of the nose, or forehead.

Vesicular Breath Sounds

Normal, expected lung sounds heard during auscultation that are characterized as clear, soft, and rustling.

Rhonchi

Continuous, low-pitched wheezy, snoring, or rattling adventitious breath sounds caused by an increased amount of mucus in the larger airways; associated with pneumonia, chronic bronchitis, cystic fibrosis, and COPD.

Crackles (Rales)

Discontinuous, popping or crackly breath sounds occurring with intervals or gaps, caused by fluid in the alveoli (air sacs); seen in respiratory distress, early congestive heart failure, asthma, and pulmonary edema.

Stridor

A high-pitched, vibrating, musical sound heard on inspiration caused by obstruction of the windpipe (trachea) or larynx; recognized as a medical emergency of the upper airway.

Wheezing

A high-pitched, continuous musical lung sound caused by narrowing or spasm of the lower bronchiole airways, frequently heard in asthma, chronic bronchitis, congestive heart failure, and COPD.
