Mixed Deck — All CPSGT Topics Flashcards

In Certified Polysomnographic Technician, what is the PRIMARY purpose of conducting regular quality improvement & patient safety assessments?

Answer: To identify potential hazards before incidents occur

Regular safety assessments are primarily conducted to proactively identify and mitigate potential hazards before they lead to incidents or injuries.

Which competency is MOST essential for professionals working in infection control & prevention in Certified Polysomnographic Technician?

Answer: Critical thinking combined with practical application of knowledge

Critical thinking allows professionals to apply knowledge effectively in varied situations, leading to better outcomes than rote procedures.

In Certified Polysomnographic Technician, how should clinical assessment & patient care results be communicated to stakeholders?

Answer: Through clear, structured reports with actionable recommendations

Clear, structured reports with actionable recommendations ensure stakeholders understand findings and can take appropriate action.

When scoring a hypopnea using the AASM recommended criteria, what percent reduction in nasal pressure signal amplitude is required?

Answer: 30%

AASM recommended criteria require a ≥30% reduction in nasal pressure signal amplitude lasting ≥10 seconds with ≥3% oxygen desaturation or an arousal.

What is the standard high-frequency filter (low-pass filter) setting for chin EMG channels in PSG?

Answer: 70 Hz

The standard high-frequency filter for chin EMG in PSG is 70 Hz, which removes high-frequency noise while preserving the EMG signal.

Which type of PAP mask interface covers only the nostrils using small cushioned inserts that seal inside the nasal openings?

Answer: Nasal pillow mask

Nasal pillow (nasal prong) masks use small cushioned inserts that fit directly into the nostrils, offering minimal contact area and are preferred by patients who feel claustrophobic with larger masks.

When should clinical assessment & patient care be conducted in Certified Polysomnographic Technician?

Answer: At regular intervals and whenever significant changes occur

Regular assessments combined with trigger-based reviews ensure ongoing monitoring while capturing the impact of significant changes.

When conducting a quality improvement & patient safety review in Certified Polysomnographic Technician, which approach yields the BEST results?

Answer: Systematic analysis using established frameworks and checklists

Systematic analysis using established frameworks ensures comprehensive coverage of all potential risks and provides consistent, reliable results.

Which sleep stage is associated with the highest arousal threshold (hardest to wake from)?

Answer: Stage N3

Stage N3 (slow wave sleep) has the highest arousal threshold, making it the most difficult stage from which to arouse a patient.

Which factor BEST indicates mastery of anatomy & physiology fundamentals in Certified Polysomnographic Technician?

Answer: The ability to adapt knowledge and skills to varying contexts while maintaining standards

True mastery is demonstrated by the ability to apply knowledge flexibly across different contexts while consistently maintaining quality standards.

Which clinical assessment & patient care method provides the MOST reliable results in Certified Polysomnographic Technician?

Answer: Standardized protocols with validated measurement tools

Standardized protocols and validated tools ensure consistency, reliability, and comparability of assessment results.

Which factor MOST impacts the usefulness of documentation & health records outputs in Certified Polysomnographic Technician?

Answer: Timeliness, accuracy, and relevance to the intended audience

Information is most useful when it is timely, accurate, and relevant to the needs of the people who will use it.

Where is the recommended placement site for the pulse oximetry probe to obtain the most reliable SpO2 readings during PSG?

Answer: Finger (index or middle)

The finger (typically index or middle finger) is the standard placement site for pulse oximetry during PSG due to reliable perfusion and signal stability.

What is the minimum number of EEG derivations recommended by AASM for standard sleep staging?

Answer: 3 derivations

AASM recommends a minimum of 3 EEG derivations (F4-M1, C4-M1, O2-M1 with backups) for standard sleep staging.

In Certified Polysomnographic Technician, how should diagnostic procedures & interpretation results be communicated to stakeholders?

Answer: Through clear, structured reports with actionable recommendations

Clear, structured reports with actionable recommendations ensure stakeholders understand findings and can take appropriate action.

Heated humidification added to PAP therapy primarily benefits patients by:

Answer: Decreasing nasal dryness and congestion to improve comfort and adherence

Heated humidification adds warmth and moisture to the airstream, reducing nasal dryness, irritation, and congestion — side effects that are among the most common reasons patients discontinue PAP therapy.

What is the PRIMARY purpose of documentation & health records in Certified Polysomnographic Technician?

Answer: To provide accurate, accessible information for decision-making and compliance

Data and documentation exist primarily to provide accurate, accessible information that supports both decision-making and regulatory compliance.

In Certified Polysomnographic Technician, how does public health & community medicine contribute to professional credibility?

Answer: By demonstrating competence, maintaining standards, and delivering consistent results

Professional credibility is built through demonstrated competence, consistent adherence to standards, and reliable delivery of quality results.

How does ongoing professional development support professional ethics & legal standards in Certified Polysomnographic Technician?

Answer: It keeps professionals informed of evolving standards and best practices

Ongoing professional development ensures that practitioners stay current with evolving regulations, standards, and best practices in their field.

What is the standard low-frequency filter (high-pass filter) setting for EEG channels in PSG?

Answer: 0.3 Hz

The standard low-frequency filter for EEG in PSG is 0.3 Hz, which preserves slow wave activity while reducing movement artifact.
