Methanol toxicity (also methanol poisoning) is poisoning from methanol, characteristically via ingestion. [1] Symptoms may include an altered/decreased level of consciousness , poor or no coordination, vomiting , abdominal pain , and a specific smell on the breath.
One study found a mean of 4.5 ppm in the exhaled breath of test subjects. [19] The mean endogenous methanol in humans of 0.45 g/d may be metabolized from pectin found in fruit; one kilogram of apple produces up to 1.4 g of pectin (0.6 g of methanol.) [20] Methanol is produced by anaerobic bacteria and phytoplankton. [21] [22]

A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
To put this into perspective, some research shows that reducing your systolic blood pressure (top blood pressure reading) by 5 mmHg may lower your risk of cardiovascular events by 10%! The Bottom Line
First and foremost, know your numbers. Blood pressure guidelines have changed over the years. In the past, 120/80 was viewed as a baseline and much higher numbers were too easily tolerated. Now we ...
If as little as 10 ml of pure methanol is ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and 30 ml is potentially fatal, [2] although the median lethal dose is typically 100 ml (3.4 fl oz) (i.e. 1–2 ml/kg body weight) of pure methanol.
