A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic, most people who entered the −2 °C (28 °F) water died in 15–30 minutes. [38]
[6] [7] For most adults, high blood pressure is present if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg. [ 5 ] [ 6 ] [ 7 ] Different numbers apply to children. [ 14 ] Ambulatory blood pressure monitoring over a 24-hour period appears more accurate than office-based blood pressure measurement .
Highest dew point temperature: A dew point of 35 °C (95 °F) — while the temperature was 42 °C (108 °F) — was observed at Dhahran, Saudi Arabia, at 3:00 p.m. on 8 July 2003. [ 202 ] Highest heat index : In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F).
A rise in the arterial partial pressure of CO 2 and, to a lesser extent, a fall in the arterial partial pressure of O 2, will reflexly cause deeper and faster breathing until the blood gas tensions in the lungs, and therefore the arterial blood, return to normal. The converse happens when the carbon dioxide tension falls, or, again to a lesser ...
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.
Summer temperatures - above 20 °C (68 °F) - begin as early as May, although in this month the sea temperature is still mild: around 17–18 °C (63–64 °F). The summer season ends in October. Over the summer season (4 months), the average temperatures is 26–29 °C (79–84 °F) during the day and the average sea temperature is 23 °C (73 ...
Top five causes of death in adults includes, stroke (14%), ischemic heart disease (7%), diabetes mellitus (4%), Cirrhosis & other chronic liver disease (3%), chronic kidney disease (3%). Among children under 5 years, the top five causes of death were neonatal disorders (43%), malaria (18%), lower respiratory tract infection (6%), diarrheal ...
[24] [2] On average, peak heart rate is increased by 5 bpm, peak systolic blood pressure is increased by 10 to 15 mmHg, and peak diastolic blood pressure is increased by 5 to 10 mmHg. [ 24 ] [ 2 ] In any case, the temporary increases in blood pressure can be a risk factor for users with pre-existing hypertension. [ 59 ]
