Pulse oximetry-derived oxygen saturation is typically >97% in normoxia and hyperoxia, limiting its clinical use. The new Oxygen Reserve Index (ORi), a relative indicator of the partial pressure of oxygen dissolved in arterial blood (PaO2) in the range of 100-200 mm Hg, may allow additional monitoring of oxygen status.

The visual interpretation of an angiographic stenosis may not always reflect the physiological significance of a lesion. Fractional Flow Reserve (FFR) is a reliable index to assess the significance of...
Validation of variable selection and predictive performance is crucial in construction of robust multivariate models that generalise well, minimise overfitting and facilitate interpretation of results...
The associations of body mass index (BMI) and obesity with ovarian reserve are controversial. This systematic review and meta-analysis was conducted to investigate the associations in reproductive-age...
To evaluate the validity of Urdu translated version of voice handicap index-10 to be used for assessing patients with voice-related complaints.
Standard care for HIV clinical practice has started focusing on age-related problems, but despite this recent change physicians involved in HIV care do not often screen HIV patients for frailty. Our a...
Masimo Corporation has developed a new parameter for noninvasive monitoring by optical sensors, Oxygen Reserve index (ORI). ORI is believed to correlate with the partial pressure of arteri...
Oxygen Reserve Index (ORI) is a new parameter for noninvasive monitoring of oxygen reserve using oximetry sensor. In this study, we will investigate the correlation between ORI and the par...
Oxygen reserve index (ORI) measured by multiple wave pulse co-oximeter is a new technological development in medical science. Our aim in this study is to identify the correlation between a...
The ORI (Reserve Oxygen Index) is an index measured through sensors SpO2 (oxygen saturation by pulse oximetry - Radical-7 MASIMO) that evaluates noninvasively PaO2 (partial pressure of oxy...
Noninvasive pulse oximetry-determined SpHb will be compared to ABG co-oximetry and research lab equipment-determined Hb values, Oxygen Reserve Index (ORI) will be correlated with paO2 via ...
Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
