The study objective is to assess the accuracy of Earlysense contactless monitoring to detect changes in blood pressure vs. Gold reference method / devices including ambulatory blood pressure monitoring device (ABPM) or invasive blood pressure monitoring for patients who have arterial line as part of their standard clinical care.
The purpose of this study is to determine the safety on sauna followed by cold water bath, a common practice in many countries, 30 healthy subjects aged 40 years and older will be at the Montreal Heart Institute Prevention and Cardiac Rehabilitation centre.
The study is designed as a prospective observational study. Each participant will have their BP, CVP, PAP, and CO measured by their clinical nurse using indwelling catheters placed for routine patient monitoring. Measurements will be recorded on an hourly basis during the day and for as many days as possible if the required measurements are being made for clinical care. Sixty patients between 18 and 85 years of age will be recruited in HVICU by means of convenience sampling. Data will be analyzed using a test of equivalence on the initial measurements (test of equivalence between two means) and then over time (repeated measurements) with a linear mixed-effects model.
In this Trial we compare a new application (App) running on an iPhone (Apple inc., Model 4S) to determine systolic blood pressure (RR) and compare it to conventional oscillometric measurements using an Omron HBP-1300-E Pro device. We will include 1000 participants and perform seven repetitive blood pressure measurements (3 iPhone, 4 Omron) in each person. Primary parameter will be the absolute difference (Delta) between the correlating blood pressure measurements in mmHg.
Individuals who experience a stroke or transient ischaemic attack (TIA) are at heightened risk of subsequent vascular events, including heart attacks and secondary stroke/TIA. Blood pressure control is considered the most important contributor to positive health outcomes in stroke patients. The measurement of central blood pressure (cSBP) (the blood pressure which is being exerted at the heart), may provide clinicians with important diagnostic and prognostic information over and above that typically obtained from a peripheral blood pressure measure (the blood pressure in the arm). Central blood pressures may be better than traditional peripheral blood pressure measures as: i) peripheral blood pressure may not accurately reflect the effects of peak arterial blood pressure on centrally located organs, ii) central blood pressures may be 50 % superior to peripheral blood pressures when predicting cardiovascular events, and iii) information pertaining to central blood pressures may be more effective in the management of hypertension. While the validity of oscillometric devices which measure central blood pressures has been demonstrated, further study is required to determine precision under normal clinical operating conditions (i.e., reflective of the Hospital/GP practice setting). As such, this study will assess central and peripheral blood pressures of stroke patients when fasted and nonfasted, and when seated and supine. The study is interested in identifying the effect of the above parameters (fasted vs. unfasted, seated vs. supine) on central and peripheral blood pressures in stroke patients. Participants will take part in three separate assessment sessions, on three separate days, with a minimum 24 hour recovery between each session. Each assessment is expected to last 90 minutes, with a minimum of eight blood pressures being taken from the left upper arm. As such, participants will be asked to give up 4.5 hours of their time to the study. During each assessment participants will be tested in a fasted and non-fasted state, and in a supine (lying) and seated position. All assessments will take place between 7 and 10am and will be undertaken following written informed consent.
Continuous noninvasive blood pressure monitoring may help to avoid intraoperative Hypotension or Hypertension
Intravenous form of oxycodone is recently used for the adjunct of anesthetic agents to avoid adverse effects of the stimulation of endotracheal intubation. The potency ratio of oxycodone to fentanyl is not absolutely defined. The aim of this study was to assess the optimal dose of intravenous oxycodone for attenuation of hemodynamic responses to laryngoscopy and endotracheal intubation. A prospective, randomized, double-blind study was conducted. Ninety one patients were randomly divided into 5 group based on the dose of oxycodone; 0, 0.05, 0.1, 0.15, 0.2 mg/kg. After giving each assigned dose of intravenous oxycodone, anesthesia was induced with thiopental and rocuronium. Heart rate (HR) and blood pressure (BP) was collected at baseline, before intubation, 1, 2, 3 minutes after intubation. The change of BP was calculated by (highest BP after intubation - baseline BP)/baseline BP.

This research project is aimed to assess the effectiveness and impact of a pediatric-based intervention aimed at reducing low-income families' unmet material needs (food, housing, employment, childcare, household heat, education and learning the English language ) on child health.
