NIOSH SSS study guide

NIOSH SSS · Work through your exam, one topic at a time.

NIOSH-approved spirometry training prepares healthcare professionals to perform and interpret spirometry in occupational health screening. It is intended for nurses, respiratory therapists, technicians, and physicians who conduct lung function testing in workplaces, clinics, or mobile screening programs. The NIOSH SSS study guide has 8 sections and about 2,255 words.

01

Indications for Spirometry and Contraindications to Testing

This domain tests whether you can justify a spirometry test, recognize when it must be deferred, and document the decision. NIOSH-aligned practice treats spirometry as a physiological stress test: forced exhalation raises intrathoracic, intra-abdominal, intraocular, and intracranial pressure.

02

Spirometer Performance, Calibration Verification, and Quality Control

This domain tests the daily and periodic checks that keep volume and flow measurements trustworthy. A spirometer that is not verified can produce precise-looking but invalid numbers.

03

Participant Preparation, Screening, and Test Safety

This domain tests the pre-test checklist that protects the participant and prevents avoidable artifacts. Obtain informed consent and explain the maneuver with a demonstration.

04

Coaching and Maneuver Technique for Acceptable Spirometry

This domain tests whether you can elicit a maximal, artifact-free forced expiratory maneuver and coach it consistently. Start from a full inspiration to total lung capacity; demonstrate and ask for a full breath in, then a blast out.

05

Acceptability and Reproducibility Criteria for Spirometry Curves

This domain tests the rules for judging whether a spirometry session is usable and how to grade it. An acceptable maneuver is free of artifacts: no cough in the first second, no glottic closure, no leak, no obstructed mouthpiece, good start (back-extrapolated volume under 5% FVC or 0.150 L), and satisfactory duration.

06

Reference Values, Interpretation, and Pattern Recognition

This domain tests selecting appropriate predicted equations, using the lower limit of normal (LLN), and recognizing obstructive, restrictive, and mixed patterns. Use equations matched to age, sex, ethnicity, and height.

07

Recordkeeping, Reporting, and Communication of Results

This domain tests what must be recorded, how long it is kept, and how results are communicated without overstepping. Record demographics, height, weight, ethnicity, test date, medications, and bronchodilator timing.

08

Infection Control and Equipment Hygiene

This domain tests practices that prevent transmission between participants and keep equipment functioning. Perform hand hygiene before and after every participant; wear gloves when handling contaminated items.
