“…Some previous studies 18,19,27,28 have validated this PM in the laboratory (i.e., concurrent with PSG) and reported good sensitivity (80% to 100%) to rule in OSA (AHI ≥ 5 events/h) but variable specificity (50% to 100%), with LR+ values ranging from 1.9 to infinity. Our study showed high diagnostic accuracy to rule in OSA with specificity 100% and LR+ infinity on the simultaneous night assessment.…”

“…Previous studies have one or more of the following limitations: (a) failure to study the PM device in its site of intended use, the home 18,19,27,28 ; (b) low sample size [16][17][18][19][20][21]27,28 ; (c) failure to collect oximetry data [16][17][18][19][20]27,29 ; (d) no randomization of order of comparison 18,19,27,28 ; and (d) no manual review of the raw PM data. [16][17][18][19][20]27,29,30 Our validation addresses these limitations.…”

“…[16][17][18][19][20]27,29,30 Our validation addresses these limitations. It examines the PM device in both the home and laboratory settings, is adequately powered, includes both flow and oximetry data, avoids order bias, and assesses the impact of manual scoring of PM data on performance.…”

Study Objectives:We hypothesized that a dual-channel portable monitor (PM) device could accurately identify patients who have a high pretest probability of obstructive sleep apnea (OSA), and we evaluated factors that may contribute to variability between PM and polysomnography (PSG) results. Methods: Consecutive clinic patients (N = 104) with possible OSA completed a home PM study, a PM study simultaneous with laboratory PSG, and a second home PM study. Uniform data analysis methods were applied to both PM and PSG data. Primary outcomes of interest were the positive likelihood ratio (LR+) and sensitivity of the PM device to "rule-in" OSA, defi ned as an apnea-hypopnea index (AHI) ≥ 5 events/h on PSG. Effects of different test environment and study nights, and order of study and analysis methods (manual compared to automated) on PM diagnostic accuracy were assessed. Results: The PM has adequate LR+ (4.8), sensitivity (80%), and specifi city (83%) for detecting OSA in the unattended home setting when benchmarked against laboratory PSG, with better LR+ (> 5) and specifi city (100%) and unchanged sensitivity (80%) in the simultaneous laboratory comparison. There were no signifi cant night-night (all p > 0.10) or study order effects (home or laboratory fi rst, p = 0.08) on AHI measures. Manual PM data review improved case fi nding accuracy, although this was not statistically signifi cant (all p > 0.07). Misclassifi cation was more frequent where OSA was mild. Conclusions: Overall performance of the PM device is consistent with current recommended criteria for an "acceptable" device to confi dently "rule-in" OSA (AHI ≥ 5 events/h) in a high pretest probability clinic population. Our data support the utility of simple two-channel diagnostic devices to confi rm the diagnosis of OSA in the home environment.

“…The oximetry was collected using a finger sensor and performed through the validated device WristOx ® , model 3150SK-04. 35 The office BP values were obtained in two moments, one before and the other after the implementation of the ABPM device. A minimum of three measurements on each day were taken and the first measurement of each one was excluded.…”

RESUMOIntrodução: A monitorização ambulatorial da pressão arterial é o melhor método de avaliação da pressão arterial e a síndrome da apneia do sono é a principal causa de mau controlo. A oximetria permite rastrear estes indivíduos mas a sua utilidade tem sido pouco explorada em Cuidados de Saúde Primários. O objectivo foi avaliar o controlo da pressão arterial no consultório e na monitorização ambulatorial da pressão arterial, e relacioná-la com a síndrome da apneia do sono. Material e Métodos: Selecionou-se uma amostra de 50 participantes, representativa de 3036 doentes hipertensos. As variáveis avaliadas foram: valor de pressão arterial no consultório e na monitorização ambulatorial da pressão arterial; presença de critérios de síndrome da apneia do sono na oximetria. Resultados: A prevalência de pressão arterial não controlada foi de 56% no consultório e 68% na monitorização ambulatorial da pressão arterial. Encontrou-se: 36% de hipertensão diurna, 52% de hipertensão nocturna, 40% de perfil não-dipper, 16% de hipertensão da bata-branca e 28% de hipertensão mascarada. A prevalência de síndrome da apneia do sono foi 16%. A pressão arterial no consultório e na monitorização ambulatorial da pressão arterial não mostrou associação estatisticamente significativa (p = 0,761). Encontrou-se uma associação estatisticamente significativa entre síndrome de apneia do sono e hipertensão diurna (p = 0,019) e perfil não-dipper (p = 0,005). Discussão e Conclusão: A monitorização ambulatorial da pressão arterial detetou mais 12% de casos de hipertensão não controlada do que o consultório. A síndrome da apneia do sono está fortemente associada a hipertensão não controlada e a oximetria pode ser um bom método de rastreio, mas deve ser mais estudada. Palavras-chave: Hipertensão; Monitorização Ambulatória da Pressão Arterial; Oximetria; Síndromes da Apneia do Sono ABSTRACT Introduction: Ambulatory blood pressure monitoring by automatic device is the best blood pressure evaluation method and sleep apnea syndrome is the leading cause of poor control. Oximetry allows screening these individuals but its usefulness has been poorly explored in Primary Health Care. The aim was to evaluate the blood pressure control at the office and with ambulatory blood pressure monitoring by automatic device and to relate it to sleep apnea syndrome. Material and Methods:We selected a sample of 50 participants, representative of 3036 hypertensive patients. The variables were: blood pressure value at the office and blood pressure with ambulatory blood pressure monitoring by automatic device; presence of criteria of sleep apnea syndrome in oximetry.Results: The prevalence of uncontrolled blood pressure was 56% on office evaluation and 68% on ambulatory blood pressure monitoring by automatic device. It was found: 36% of daytime hypertension, 52% nocturnal hypertension, 40% non-dipper profile, 16% of white coat hypertension and 28% masked hypertension. The prevalence of sleep apnea syndrome was 16%. Blood pressure in ambulatory blood pressure monitoring by...
