Spirometry

MEDICAL ASSISTANT

Definition

Pulmonary function test measuring FEV1 and FVC to diagnose/monitor respiratory conditions.

Assessment Techniques

Pulse: Radial (most common), count 60 sec if irregular. Apical: left MCL, 5th ICS, count 60 sec. Pulse deficit: apical minus radial.. Normal: Normal adult: 60-100 bpm. Tachycardia over 100, bradycardia under 60.

Respirations: Count without patient awareness (keep fingers on wrist), observe chest rise, count 30 sec x 2 or 60 sec if irregular. Normal: Normal adult: 12-20/min. Tachypnea over 20, bradypnea under 12.

Overview

Pulmonary function test measuring FEV1 and FVC to diagnose/monitor respiratory conditions. Spirometry procedure tested on MA exam.

Clinical connection: Blood pressure technique involves Seated, arm at heart level, cuff on bare upper arm, inflate 30mmHg above palpated systolic, deflate .

Regulatory Context

Regulatory context for spirometry includes federal and state requirements. Healthcare facilities must comply with CMS Conditions of Participation, state licensure requirements, and accreditation standards (Joint Commission or AAAHC). Non-compliance can result in citations, fines, or loss of Medicare/Medicaid reimbursement.

Step-by-Step Procedure

Procedure: Respirations measurement (relevant to spirometry).

Technique: Count without patient awareness (keep fingers on wrist), observe chest rise, count 30 sec x 2 or 60 sec if irregular

Normal values: Normal adult: 12-20/min. Tachypnea over 20, bradypnea under 12.

Practical Example

Clinical Procedure: Temperature measurement is relevant to spirometry.

Technique: Oral (under tongue, lips closed, 3-5 min), tympanic (pull ear up and back for adults), temporal (across forehead)

Normal values: Oral: 97.8-99.1 F. Rectal: +1 F. Axillary: -1 F. Tympanic: close to core.

Frequently Asked Questions

What coding system is used for spirometry?
For spirometry: CPT: Procedure coding with 5-digit numeric codes, maintained by AMA. Examples: 99213: Established patient office visit (low complexity); 36415: Venipuncture; 93000: Electrocardiogram (12-lead).
What injection technique applies to spirometry?
For spirometry: Intramuscular: angle 90 degrees, sites: Vastus lateralis (thigh), Deltoid (upper arm), Ventrogluteal (preferred for adults), Dorsogluteal (avoided due to sciatic nerve risk). Max volume: Deltoid max 1mL, VG/VL max 3mL. Needle: 21-23G, 1-1.5 inch.
What vital sign procedure relates to spirometry?
For spirometry: Temperature: Oral (under tongue, lips closed, 3-5 min), tympanic (pull ear up and back for adults), temporal (across forehead). Normal: Oral: 97.8-99.1 F. Rectal: +1 F. Axillary: -1 F. Tympanic: close to core..
