Respiration data on sleep state misperception, psychophysiological insomnia and normal individuals from a cross sectional study

The data prepared here had been originally collected for a study project entitled ‘Breathing pattern analysis in insomnia suffers’. This data describes the information of 82 individuals; participating 41 normal individuals and 41 insomnia suffers with tow phenotype included 30 sleep state misperception and 11 psychophysiological suffers. The data presents 8 hours of respiratory signals included flow pressure, flow temperature, Oxygen saturation, Thorax and Abdomen signal in frequency sampling 256, 32, 32, 32, 4 Hz respectively. It includes breathing features and sleep profiles in segments of 30s for each individuals. In addition, the full demographic and objective specifications was attached.


Data
The data of this article provides information about the cross-sectional study entitled "Breathing pattern analysis in insomnia suffers". All of the data prepared in three category including table, text, and matrices and arrays indexed in Matlab. Demographic information, Subjective sleep parameters, objective sleep parameters such as apnea-hypopnea index, minimal and average SpO2, present of sleep stages, TST and %SE presented in an Excel file. Sleep profiles and breathing features such as flow events and SpO2 events presented in segments of 30s for each individual during sleep as text file. Respiratory signals of all participants were collected in matrices and arrays indexed in Matlab as mat format. The data presents 8 hours of respiratory signals included flow pressure, flow temperature, Oxygen saturation, thorax and abdomen signal in frequency sampling 256, 32, 32, 32, 4 Hz respectively (Figs. 1 and 2). It should be noted that the respiratory signals were filtered other than SpO2 using the low pass filter of 1 Hz by SOMNOscreenTM plus device. Signals were arranged in the form of structure array. They were named as X_XX.mat in which 'X' represents individuals subtype such as normal, sleep state misperception suffers and psychophysiological insomniacs and so 'XX' represents the name of signal such as PressureFlow, FlowTh, SpO2, Thorax and Abdom. The names of data and their descriptions was listed in Table 1. The dataset is freely available at [1] for any academic, educational, and research purposes.
Specifications Table   Subject Psychiatry, Sleep disorder Specific subject area Respiratory, insomnia, Sleep Type of data Value of the data The data includes information that is both raw and analyzed which could be utilized in other studies. The data included 8 hours of respiratory signals during sleep bouts (flow pressure, flow temperature, SpO2, Thorax, Abdomen) from 82 individuals; participating 41 normal individuals and 41 insomnia suffers with tow phenotype included 30 sleep state misperception and 11 psychophysiological suffers. Respiratory analysis and investigating role of oxygen in each stage of sleep and brain function is important. The data can likewise be utilized to assess the pattern of breathing in sleep state misperception and psychophysiological suffers.
The diagnosis was subjectively and objectively performed by a sleep specialist, based on sleep highlights.

Sample collection
There were the 82 individuals from 16 to 64 years of age (39.77(13.40)) recruited for participating included 39 males (47.56%) and 43 females (52.44%). Thirty and eleven individuals suffered respectively from sleep state misperception and psychophysiological insomnia among the participants. Other individuals as normal sleeper were chosen from general people. Initially, normal sleepers were chosen based on Pittsburgh questionnaire. Finally, we selected normal sleeper who were normal according to the result of PSG (Table 2).

Procedure
Invited participants to sleep laboratory recommended avoiding coffee, tea, heavy diet and a cigarette. Using clinical interview by a sleep specialist according to ICSD II [2], insomnia suffers selected initially. In addition, normal sleeper were also interviewed to exclude any sleep disorders. All of participants completed the demographic and subjective questionnaire in Persian version to measure subjective sleep characteristics. The Pittsburgh questionnaire was used for this purpose. PSQI is a selfreport questionnaire evaluating subjective sleep over an interval of 1 month. The measure is made up of seven components to calculate a global score as sleep quality index [3]. Next, PSG test used to objective data acquisition. The test duration was about 8 hours. Polysomnography device called SOMNOscreenTM plus PSG manufactured by SOMNOmedics GmbH, Germany. Finally, based on both subjective and objective information data, insomnia diagnosis was done. PSG room has been standardized for audial and visual stimulation and any artifact according to international standards [4].

Ethical approval
All procedures performed in the data collection involving human participants were in accordance with the ethical standards of the Ethical Research Committee of Kermanshah University of Medical Sciences, and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. In addition, informed consent was obtained from all individual participants.
