The pneumonia severity index (PSI) or PORT Score is a clinical prediction rule that medical practitioners can use to calculate the probability of morbidity and mortality among patients with community acquired pneumonia. [1] The PSI/PORT score is often used to predict the need for hospitalization in people with pneumonia. [2]
CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia [1] and infection of any site. [2] The CURB-65 is based on the earlier CURB score [3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia. [4]
Levine postulated four main principles that the nurse follow to facilitate healing a patient. They are conserving the patient's: Energy; Structural integrity; Personal integrity; Social integrity; The conservation model of nursing is based around the law of conservation of energy, combined with the psycho-social aspects of the individual's ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...
Most of the time, however, energy consumption is composed of both fats and carbohydrates. The approximate respiratory quotient of a mixed diet is 0.8. [1] Some of the other factors that may affect the respiratory quotient are energy balance, circulating insulin, and insulin sensitivity. [2] It can be used in the alveolar gas equation.
Metabolism comprises the processes that the body needs to function. [2] Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest. Some of those processes are breathing , blood circulation , controlling body temperature , cell growth , brain and nerve function, and contraction of ...
Pulmonary compliance is calculated using the following equation, where ΔV is the change in volume, and ΔP is the change in pleural pressure: = For example, if a patient inhales 500 mL of air from a spirometer with an intrapleural pressure before inspiration of −5 cm H 2 O and −10 cm H 2 O at the end of inspiration.
