Best Notes App for Polysomnographic Technologists (iPhone)

Sleep technologists set up and monitor overnight sleep studies across complex physiological channels. Here's how to use Nemos on iPhone for RPSGT study setup, CPAP titration, and events logging.

·By Taha Baalla

Sleep technology is nocturnal, specialized, and detail-dependent. A good polysomnographic technologist (RPSGT) tracks dozens of physiological channels simultaneously through the night—EEG, EMG, EOG, airflow, respiratory effort, SpO2, ECG—while also managing patient comfort and troubleshooting equipment issues. The notes you take during a study inform scoring, reporting, and protocol adjustments. This guide shows how sleep technologists use iPhone notes to organize their work.

The Sleep Lab Documentation Challenge

Formal sleep study documentation—the PSG report with sleep staging, respiratory event scoring, and AHI calculation—lives in your lab's specialized software. But the surrounding clinical context—what the patient reported about their sleep, the epoch where sensor artifact occurred, the positioning change that improved airflow signal—needs to be captured in real time.

⚠️ HIPAA note: Polysomnography is a healthcare service. Patient information is protected health information. Use de-identified study codes in personal notes. Formal study documentation belongs in your HIPAA-compliant sleep lab system.

How Nemos Works for Sleep Technologists

Create spaces in Nemos for different study protocols (diagnostic/titration/split-night/MSLT/MWT), patient population notes, and continuing education. Notes sync across iPhone and Mac.

Study Setup and Protocol Notes

Pre-study setup note: ``` Study - [code] [date] Study type: [diagnostic/CPAP titration/split-night/MSLT/MWT] Protocol: [institutional protocol version]

Patient interview highlights: - Sleep complaints: [chief complaint in patient's words] - Sleep schedule: [typical bedtime/wake time] - Medications: [relevant to sleep — sleep aids, stimulants, opioids] - Caffeine/alcohol: [if reported] - Prior sleep study: [if any, type, findings]

Electrode/sensor placement: - Scalp: [any placement challenges] - Face: [airflow, effort, chin EMG] - Legs: [EMG placement] - Other: [SpO2, ECG, position sensor]

Impedances: [achieved or problematic channels] Calibrations: [completed/issues] Start time: [lights out] ```

Night events log: ``` Study events - [code] [date] Time [HH:MM]: [event — patient turned over / artifact on C3 / removed mask / position change / arousals cluster / etc.] Time [HH:MM]: [event] Time [HH:MM]: [event]

CPAP titration (if applicable): - Starting pressure: [cmH2O] - Pressure adjustments: [time, pressure, reason] - Final pressure: [cmH2O] - Mask tolerance: [notes]

Artifact log: [channels affected, time range, cause if known] ```

CPAP Titration Notes

``` CPAP titration - [study code] Mask type: [nasal/full face/nasal pillows] Starting pressure: [cmH2O] Response pattern: [events at each pressure level] Optimal pressure: [cmH2O, rationale] Residual events: [any at final pressure] Patient tolerance: [mask leak, comfort issues] PAP therapy education: [what was covered] Recommended settings: [to report to prescribing physician] ```

MSLT and MWT Protocol Notes

``` MSLT/MWT - [study code] [date] Prior night study: [yes/no, AHI if relevant] Protocol: [number of naps, spacing] Nap times: [scheduled] Sleep latencies: [mean across naps] SOREMP: [number of sleep-onset REM periods] Patient behavior between naps: [any sleep deprivation concerns] Medications night before: [relevant] Technical issues: [any affecting data quality] ```

Scoring Reference Notes

``` Scoring notes - [topic] AASM version: [3.0/earlier] Rule: [specific scoring criterion] My interpretation: [how I apply this rule] Edge cases: [situations that require judgment] Reference: [AASM rule citation] ```

These personal scoring reference notes help standardize your approach across studies.

Equipment and Troubleshooting Notes

``` Equipment reference - [device/sensor type] Setup procedure: [key steps] Common issues: [problems and solutions] Artifact patterns: [what various artifacts look like] Maintenance: [cleaning, calibration intervals] ```

FAQ

Can I use Nemos instead of my sleep lab's PSG software? No. Your PSG software is the system of record for all formal sleep study data, staging, and reporting. Nemos supports your real-time observation capture during studies and your professional knowledge base.

What's the most important event to log during an overnight study? Any event that will affect scoring or interpretation—artifact windows, patient interventions, mask removal/replacement during titration, position changes that coincide with respiratory event clusters. Timestamped events protect you if questions arise during scoring.

How do I handle the challenge of keeping notes during an overnight study without disturbing the patient? Keep your notes brief during the study—timestamps and one-line observations. Expand them at the end of the study before the next patient arrives, while the night is fresh.

Is Nemos useful for RPSGT exam preparation? Yes—study spaces for sleep staging rules, AASM scoring criteria, respiratory event definitions, and polysomnography equipment knowledge are well-organized in Nemos.

What about protocol variations between labs I float to? Create protocol reference notes per lab when you float regularly. Key differences in sensor placement, titration algorithms, or documentation requirements between labs are exactly what you want documented somewhere accessible.

How do I document patient education about PAP therapy or sleep hygiene? Note what was covered and patient's response. This supports continuity if the patient returns for a follow-up titration.

Can I use Nemos for pediatric sleep study notes? Yes—pediatric protocols differ from adult. A reference space for pediatric normal values, age-specific scoring criteria, and positioning/equipment modifications for pediatric patients is useful.
