Summary In this paper, the use of various pressure measurements is investigated for determining formation pressure and permeability distributions by use of the multiprobe formation testing packer and probe modules (PPM's) in horizontal wells. It is shown that reservoir pressure measurements along the wellbore give local and reservoir-scale information about how the reservoir is being depleted and how cleanup takes place. The estimation of horizontal and vertical permeabilities, skin, and reservoir pressure along the wellbore is also presented by use of interval (local) pressure transient tests. For PPM in horizontal wells, an interpretation method is presented for determining the reservoir parameters. A few interval pressure transient test (IPTT) examples are presented for formation pressure and permeability distributions, and fluid sampling. Introduction With the increasing number of horizontal wells, in addition to conventional well tests, interval tests have been conducted in many wells for formation pressure, permeability, and fluid sampling. We present the use of interval (local or sectional) pressure transient testing techniques for different reservoir and wellbore conditions in horizontal wells. Because they are dynamic and direct, pressure measurements and interval (local) transient tests provide essential information for well productivity and dynamic reservoir description, and hold critical importance for exploration as well as production and reservoir engineering. For exploration, pressure measurements and interval tests may simply show that the formation is able to produce, may permit sampling of the formation fluid, and may provide productivity index, reservoir pressure, permeability, and data for heterogeneity.

The aim of the study was to determine the effectiveness of giving hydrotherapi foot soak in hypertensive patients. The study was conducted with one group pretestposttest design without a control group by measuring blood pressure (pretest) before being given an intervention in the form of foot soak hydrotherm against 15 people with hypertension in Banjar Sri Mandala, Dauhwaru Village, Jembrana Subregency. Then do the blood pressure measurement again (posttest) after finishing the intervention. After the study was completed, the results showed that before the hydrotherapi foot bath intervention, there were 0% of patients classified as normal, 13.32% in prehypertension category, 60.08% in hypertension category I and 26.60% in hypertension category II. After the intervention was given, there were 13.32% of the patients classified as normal, 66.68% in the prehypertension category, 20.00% in the first category of hypertension and no patients belonging to the second grade hypertension category. There is a decrease of 20-30 mmHg for systolic blood pressure and 0-10 mmHg for diastolic blood pressure after intervention. Based on the results of the study it can be concluded that the hydrotherapi foot bath is effectively used to reduce blood pressure in hypertensive patients in the Banjar Sri Mandala, Dauhwaru Village, Jembrana District.

Measure Blood Pressure

The continuous blood pressure measurement research is widely known for helpingthe development of ambulatory blood pressure monitoring where it measures blood pressureevery 15 to 30 minutes throughout the day. The cuff is a problem for the patient withAmbulatory Blood Pressure Monitor. It can make a person feel uncomfortable and must staystill when the cuff starts to inflate. It is limiting and disturbing their daily activity when thedevice is starting to measure the blood pressure. Blood pressure measurement without cuff isbeing proposed in this research, called cuff-less blood pressure measurement. It will be based onPhotoplethysmography (PPG) and Electrocardiography (ECG) signal analysis. ECG (Lead 1,Lead 2, and Lead 3) with PPG signal produced from index finger on the left hand are comparedand analyzed. Then the relation of PPG and ECG signal and the optimum location for daily usecan be obtained. The optimum location will be based on the electrode’s position that producedthe optimum ECG lead Signal to measure blood pressure. Based on the result, PPG and ECGsignal have a linear relation with Blood Pressure Measurement and Lead 1 is more stable inproducing the ECG signal. The equation from Lead 1 appeared as one of the optimum equationsfor measuring Systolic Blood Pressure (SBP) or Diastolic Blood Pressure (DBP).
