Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [ 1 ]
Tea and toast syndrome is a form of malnutrition commonly experienced by elderly people who cannot prepare meals and tend to themselves. The term is not intrinsic to tea or bread products only; rather, it describes limited dietary patterns that lead to reduced calories resulting in a deficiency of vitamins and other nutrients.
PFT may refer to: Medical and fitness. Physical Fitness Test, a test of an individual's physical fitness such as ability to exercise, etc. ... Print for time, ...
This measurement is often used under treatment with a heart lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy. Tissue oxygen saturation (StO 2) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea ...
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide.An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [1] but sometimes the femoral artery in the groin or another site is used.
To interpret the significance of peak expiratory flow measurements, a comparison is made to reference (normal, predicted) values based on measurements taken from the general population. Various reference values have been published in the literature and vary by population, ethnic group, age, sex, height and weight of the patient.
As the patient tries to inhale (a maneuver which looks and feels like panting), the lungs expand, decreasing pressure within the lungs and increasing lung volume. This, in turn, increases the pressure within the box since it is a closed system and the volume of the box compartment has decreased to accommodate the new volume of the subject.
Device for spirometry. The patient places his or her lips around the blue mouthpiece. The teeth go between the nubs and the shield, and the lips go over the shield. A nose clip guarantees that breath will flow only through the mouth. Screen for spirometry readouts at right. The chamber can also be used for body plethysmography.
