In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3] [10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2]
The rate of cellular metabolic activity affects and, at the same time, is affected by the pH of the body fluids. In mammals, the normal pH of arterial blood lies between 7.35 and 7.50 depending on the species (e.g., healthy human-arterial blood pH varies between 7.35 and 7.45). [citation needed]
Fever is considered temperature of 37.8 °C (100.0 °F) or above. [13] Other causes of elevated temperature include hyperthermia, which results from unregulated heat generation or abnormalities in the body's heat exchange mechanisms. [13] Temperature depression (hypothermia) also needs to be evaluated. Hypothermia is classified as temperature ...
Fever of unknown origin (FUO) refers to a condition in which the patient has an elevated temperature for which no cause can be found despite investigations by one or more qualified physicians. [1] [2] [3] If the cause is found, it is usually a diagnosis of exclusion, eliminating all possibilities until only the correct explanation remains.
A nursing diagnosis may be part of the nursing process and is a clinical judgment about individual, family, or community experiences/responses to actual or potential health problems/life processes. Nursing diagnoses foster the nurse's independent practice (e.g., patient comfort or relief) compared to dependent interventions driven by physician ...
If elevated lactate is present in acute illness, supporting the oxygen supply and blood flow are key initial steps. [3] Some vasopressors (drugs that augment the blood pressure) are less effective when lactate levels are high, and some agents that stimulate the beta-2 adrenergic receptor can elevate the lactate further.

The sealed syringe is taken to a blood gas analyzer. [8] If a plastic blood gas syringe is used, the sample should be transported and kept at room temperature and analyzed within 30 min. If prolonged time delays are expected (i.e., greater than 30 min) prior to analysis, the sample should be drawn in a glass syringe and immediately placed on ...
