In this study, a mathematical model of Anti-Lock Braking System (ABS) has been developed and simulated in MATLAB/Simulink environment using bang-bang, fuzzy logic PID controllers. The controllers were used to control the braking force be applied based on various parameters like relative slip, road condition coefficient friction between tire. result was compared analyzed. simulation showed that ...

OBJECTIVE To validate the Portuguese-language version of the STOP-Bang (acronym for Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender) questionnaire, culturally adapted for use in Brazil, as a means of screening for obstructive sleep apnea (OSA) in adults. METHODS In this validation study, we enrolled patients ≥ 18 years of age, recr...

BACKGROUND STOP-BANG score (snore; tired; observed apnea; arterial pressure; body mass index; age; neck circumference and gender) can predict the risk of a patient having Obstructive Syndrome Apnea (OSA). The aim of this study was to evaluate the incidence STOP-BANG score≥3, in surgical patients admitted to the Post-Anesthesia Care Unit (PACU). METHODS Observational, prospective study conduct...

INTRODUCTION Patients with STOP-BANG score >3 have a high risk of Obstructive sleep apnea. The aim of this study was to evaluate early postoperative respiratory complications in adults with STOP-BANG score >3 after general anesthesia. METHODS This is a prospective double cohort study matching 59 pairs of adult patients with STOP-BANG score >3 (high risk of obstructive sleep apnea) and patient...

background and objective: obstructive sleep apnea (osa) is the most common respiratory disorder during sleep and a risk factor for myocardial ischemia. in this study, we evaluated the proportion of subjects at high risk for osa and prevalence of its predictors among patients admitted for acute myocardial infarction (mi). materials and methods : a total of 210 patients with mi admitted at the ca...

STUDY OBJECTIVES To determine the prevalence of sleep complaints in adults in Colombia at different altitudes. DESIGN Cross-sectional, population-based and observational study. SETTING Urban areas in three cities (Bogotá, Bucaramanga, Santa Marta) located between 15 and 2640 masl. Subjects Over 18 years old. INTERVENTIONS Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQ...

OBJECTIVE To determine whether high risk scores on preoperative STOP-BANG (Snoring, Tiredness during daytime, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, Gender) questionnaires during preoperative evaluation correlated with a higher rate of complications of obstructive sleep apnea syndrome (OSAS). DESIGN Historical cohort study. SETTING Thomas Jefferson Un...

OBJECTIVES Little is known about the early recovery phase occurring at-home after anesthesia and surgery in ambulatory surgical patients. We studied quantitative oximetry and quality-of-life metrics in the first 48 hours after same-day orthopedic surgery examining the association between the recovery metrics and specific patient and procedural factors. METHODS We used the STOP-Bang score to q...
