The phrase "airflow finger" is not a standard expression in written English, but it could be correct depending on the context.
You can use it in technical or specialized discussions related to airflow measurement or control, possibly in engineering or HVAC contexts.
Example: "The technician adjusted the airflow finger to optimize the ventilation system's performance."
Alternatives: "airflow indicator" or "airflow gauge".
Polysomnographic (PSG) recordings were performed from 23:00 to 06:00 h including monitoring of the EEG (C4-A1 and C3-A2), electrooculogram, submental electromyogram (EMG), the right and left anterior tibialis surface EMG, electrocardiogram (EKG), thoracic and abdominal movements, nasal airflow, finger oximetry, and video monitoring.
The ApneaLink Plus records oxygen saturation and pulse rate with a finger probe, nasal airflow with a nasal pressure cannula and respiratory effort with a pneumatic sensor belt.
All participants also had simultaneous, clinically standard respiratory monitoring comprising: finger oximetry; oronasal airflow sensors; thoracic and abdominal expansion bands; and ECG; using the SOMNO polysomnography system (SOMNOscreen RC kombi. SOMNO Medics, Germany) (figure 1(B)).
Overnight polysomnography was performed with continuous recording of the following channels: electroencephalogram, electro-oculogram, chin electromyogram, Sa o2 (finger oximetry), nasal-oral airflow (pressure cannula), electrocardiogram, chest and abdominal wall motion (piezoelectrodes), bilateral tibialis electromyogram, and body position.
Patients in the PSG population, who were only evaluated for sleep apnea, underwent an ambulant sleep apnea recording using the Embla system (EMBLA; Medcare-Flaga; Reykjavik, Iceland), recording airflow with thermistors, oxygen saturation by finger-pulse oximeter, heart rate, abdominal and thoracic respiratory movements, body position and snoring.
To take advantage of airflow, the three buildings resemble three fingers reaching toward the bay to catch prevailing winds.
The overnight sleep PSG included four electroencephalogram channels (C4-A1, C3-A2, O2-A1, O1-A2 [ 57]), an electro-oculogram (two channels), a submental electromyogram (EMG), a finger pulse oximetry, an oronasal airflow (oronasalthermistor), a chest and abdominal movement belt (respiratory inductance plethysmography), a vibration snore sensor and an anterior tibialis EMG.
I had chest and stomach belts for breathing, an airflow sensor in my nostrils, an oxygen saturation monitor on my finger and a "snore mike" taped to my neck.
A previously validated non-attended respiratory polygraphy was performed at patients' homes with a Somnea polygraph (Compumedics, Abbotsford, Australia) which records nasal airflow (nasal cannula), respiratory effort (chest and abdominal bands), snoring, body position and finger pulse oxymetry [11].
This device produces a computorized recording of variations in oronasal airflow (measured by nasal cannula), body position, wrist actimetry, pulse rate and arterial oxygen saturation (measured by finger pulse oximetry).
PSG (Neurofax EEG 1100 system, Nihon Kohden, Foothill Ranch, CA) included recordings of six electroencephalographic channels, bilateral electro-oculograms, chin and tibialis electromyogram, electrocardiogram, airflow by nasal pressure transducer and oronasal thermocouples, chest and abdominal wall motion by piezo electrode belts, and oxygen saturation by finger pulse oximeter.
