Lesson 2 • Upper and Lower Airway Anatomy

This topic identifies nasal passages, pharynx, larynx, trachea, bronchi, and alveoli relevant to airflow measurement. It provides a structural basis for understanding spirometric lung volumes.

Lesson 3 • Physiological Basis of Sound and Airflow

This module introduces sound wave properties and airflow dynamics as measurable physical phenomena. It grounds you in the physics underlying both audiometric and spirometric measurements.

Lesson 4 • Inner Ear and Auditory Nerve Pathways

This section examines cochlear structure, hair cell function, and neural transmission to the auditory cortex. It connects inner ear physiology to sensorineural hearing loss patterns.

Lesson 1 • Sound Measurement and the Audiogram

This module defines frequency, intensity, and hearing threshold level as plotted on the audiogram grid. You will read and orient a standard audiogram before performing any testing.

Lesson 2 • Occupational Hearing Conservation Context

This topic situates audiometric testing within workplace noise exposure monitoring and hearing conservation programs. You will connect test results to occupational health surveillance goals.

Lesson 3 • Hearing Loss Classification Systems

This module presents degree and type classifications of hearing loss using threshold averages. You will apply classification criteria to audiogram data to describe patient hearing status.

Lesson 4 • Types of Audiometric Tests

This topic distinguishes pure-tone air conduction, bone conduction, speech audiometry, and immittance testing. Each test type is linked to the hearing pathway component it evaluates.

Lesson 1 • Masking Principles and Application

This module explains cross-hearing, interaural attenuation, and the plateau method for effective masking. You will calculate masking levels and apply them during air and bone conduction tests.

Lesson 2 • Bone Conduction Testing Technique

This topic instructs on oscillator placement, forehead versus mastoid positioning, and masking necessity. You will determine when bone conduction is required and apply correct masking levels.

Lesson 3 • Pre-Test Patient Preparation

This section covers otoscopic inspection, noise exposure history, and patient instruction protocols. Proper preparation reduces test errors and ensures valid threshold measurements.

Lesson 4 • Tympanometry and Acoustic Reflex Testing

This module guides probe tip selection, seal verification, and tympanogram interpretation by curve type. You will classify tympanograms and identify acoustic reflex presence or absence.

Lesson 1 • Documenting and Reporting Findings

This module establishes standards for audiometric report content, terminology, and referral recommendations. You will draft reports that meet occupational health and clinical documentation requirements.

Lesson 2 • Speech Audiometry Result Interpretation

This topic interprets speech recognition threshold and word recognition score in relation to pure-tone findings. You will identify agreement or discrepancy between speech and pure-tone results.

Lesson 3 • Identifying Audiogram Patterns

This module teaches recognition of flat, sloping, notched, and rising audiogram configurations. Pattern recognition guides differential interpretation and appropriate referral decisions.

Lesson 4 • Differentiating Hearing Loss Types

This topic uses air-bone gap analysis to distinguish conductive, sensorineural, and mixed losses. You will apply decision rules to audiogram data to assign the correct loss type.

Lesson 1 • Key Spirometric Parameters

This module introduces FVC, FEV1, FEV1/FVC ratio, and peak expiratory flow as primary diagnostic indices. You will explain the clinical significance of each parameter before performing tests.

Lesson 2 • Obstructive and Restrictive Patterns Overview

This section introduces the physiological basis of obstructive and restrictive ventilatory defects. You will distinguish pattern types conceptually before applying interpretation criteria in later chapters.

Lesson 3 • Spirometry Equipment Types

This topic compares volume-displacement and flow-sensing spirometer designs, including turbine and pneumotachograph types. You will select appropriate equipment based on clinical setting and test requirements.

Lesson 4 • Reference Values and Predicted Normals

This module explains how age, height, sex, and ethnicity determine predicted normal spirometric values. You will apply reference equations to calculate percent-predicted values for patient results.

Lesson 1 • Acceptability and Repeatability Criteria

This module applies published criteria for start-of-test, end-of-test, and between-maneuver reproducibility. You will evaluate each trial and determine when sufficient acceptable maneuvers are obtained.

Lesson 2 • Performing the Forced Vital Capacity Maneuver

This topic teaches maximal inhalation, blast start, sustained effort, and end-of-test criteria for the FVC maneuver. You will coach patients through each phase to achieve acceptable effort.

Lesson 3 • Slow Vital Capacity and MVV Maneuvers

This module instructs on slow vital capacity technique and maximum voluntary ventilation as supplementary maneuvers. You will identify when each adds diagnostic value beyond the standard FVC test.

Lesson 4 • Equipment Calibration and Quality Control

This section establishes daily calibration verification, leak testing, and biological control procedures for spirometers. You will perform and document calibration checks before each testing session.

Lesson 1 • Classifying Ventilatory Patterns

This topic uses the FEV1/FVC ratio and FVC percent-predicted to classify obstructive, restrictive, and mixed patterns. You will apply a stepwise algorithm to reach a pattern classification from test values.

Lesson 2 • Flow-Volume Loop Analysis

This module interprets flow-volume loop shape to identify effort, obstruction, restriction, and upper airway patterns. You will recognise characteristic loop morphologies that supplement numerical interpretation.

Lesson 3 • Grading Severity of Impairment

This section applies FEV1 percent-predicted thresholds to grade obstruction severity from mild to very severe. You will assign severity grades and link them to clinical management implications.

Lesson 4 • Selecting the Best Test Values

This topic applies rules for selecting the largest FVC and FEV1 from acceptable maneuvers for reporting. You will distinguish best-value selection from the single best-maneuver approach.

Lesson 1 • Infection Control and Equipment Hygiene

This module establishes disinfection protocols for audiometric and spirometric equipment between patients. You will apply appropriate cleaning levels based on device contact classification.

Lesson 2 • Simulated Case-Based Testing Sessions

This topic applies audiometric and spirometric procedures to standardised patient scenarios with varied presentations. You will manage test sequencing, coaching, and real-time decision-making under supervision.

Lesson 3 • Program-Level Quality Assurance

This module establishes metrics for monitoring tester performance, equipment calibration trends, and data completeness. You will design a quality assurance checklist applicable to your testing program.

Lesson 4 • Referral Pathways and Follow-Up Protocols

This module defines criteria triggering referral to audiology, pulmonology, or occupational medicine specialists. You will apply decision trees to case data to initiate appropriate follow-up actions.
