The median lethal dose of theobromine for dogs is 100–200 mg/kg (0.0016–0.0032 oz/lb); therefore, a 10 kg (22 lb) dog would need to consume a minimum of 200 g (7.1 oz) of the most theobromine-rich (5 g/kg (0.080 oz/lb)) dark chocolate, or a maximum of 1 kg (2.2 lb) (of theobromine-rich milk chocolate), to have a 50% chance of receiving a ...
The sitting-rising test (SRT) is a clinical test which provides a significant and efficient prediction of mortality risk in the elderly. It was initially developed by Brazilian researchers in exercise physiology and sports medicine in the 1990s. The test involves sitting on the floor, then returning to a standing position from the floor.
The most common victims of theobromine poisoning are dogs, [8] [9] for whom it can be fatal. The toxic dose for cats is even lower than for dogs. [10] However, cats are less prone to eating chocolate since they are unable to taste sweetness. [11] Theobromine is less toxic to rats and mice, who all have an LD 50 of about 1,000 mg/kg (0.016 oz/lb).
Tolerable weekly intake (TWI) estimates the amount per unit body weight of a potentially harmful substance or contaminant in food or water that can be ingested over a lifetime without risk of adverse health effects. [1] [2] TWI is generally preceded by "provisional" to indicate insufficient data exists, increasing uncertainty. [3]
Experts suggest to move around and change positions throughout the day. It is best not to sit in one position for more than 20 minutes, or to stand in one position for more than 8 minutes. [17] If prolonged sitting in the workplace is required or desired, individuals should gradually transition to significant periods of standing. [18]
In the Trendelenburg position (/ ˈ t r ɛ n d əl ən b ɜːr ɡ /), the body is lain supine, or flat on the back on a 15–30 degree incline with the feet elevated above the head. [1] The reverse Trendelenburg position, similarly, places the body supine on an incline but with the head now being elevated.
Only continuous beat-to-beat BP measurement during an active standing-up maneuver can document this condition. [32] Classic orthostatic hypotension is frequently characterized by a systolic blood pressure decrease of ≥20 mmHg or diastolic blood pressure decrease of ≥10 mmHg between 30 seconds and 3 min of standing. [33]
ASHRAE 55 provides a table of metabolic rates for a variety of activities. Some common values are 0.7 met for sleeping, 1.0 met for a seated and quiet position, 1.2–1.4 met for light activities standing, 2.0 met or more for activities that involve movement, walking, lifting heavy loads or operating machinery.
