Answer: The relationship between blood pressure and heart rate responses to coughing was investigated in 10 healthy subjects in three body positions and compared with the circulatory responses to commonly used autonomic function tests: forced breathing, standing up and the Valsalva manoeuvre. 2. We observed a concomitant intra-cough increase in supine heart rate and blood pressure and a sustained post-cough elevation of heart rate in the absence of arterial hypotension. These findings indicate that the sustained increase in heart rate in response to coughing is not caused by arterial hypotension and that these heart rate changes are not under arterial baroreflex control. 3. The maximal change in heart rate in response to coughing (28 +/- 8 beats/min) was comparable with the response to forced breathing (29 +/- 9 beats/min, P greater than 0.4), with a reasonable correlation (r = 0.67, P less than 0.05), and smaller than the change in response to standing up (41 +/- 9 beats/min, P less than 0.01) and to the Valsalva manoeuvre (39 +/- 13 beats/min, P less than 0.01). 4. Quantifying the initial heart rate response to coughing offers no advantage in measuring cardiac acceleratory capacity; standing up and the Valsalva manoeuvre are superior to coughing in evaluating arterial baroreflex cardiovascular function.
Explanation:
1. Attraction for other polar molecules.
2. Stores heat, High specific heat!
3. Stores hear, High heat of Vaporization
4. Low density of Ice
5. HIGH POLARITY!
6. Water has high surface tension
7. Water has the ability to carry ELECTRIC current
8. Is a UNIVERSAL solvent= has the ability to dissolve so many substances
9. Water occurs naturally on earth in three forms; solid, liquid, and gas.
Chronic lymphocytic leukemia or the CLL is among the most common type of leukemia affecting the adults. The lymphocytic leukemia starts in the lymphocytes. Lymphocytic leukemia is different from the lymphoma (which also occur in the lymphocytes) as it only occurs in the bone marrow and the blood. The person suffering from CLL is susceptible to an array of infections. Among the various infectious agents, the CLL patient is the most susceptible to the Staphylococcus aureus. This agent causes skin infections, pneumonia, toxic shock syndrome and many other life threatening diseases. The person becomes susceptible to its attack as the immunity of his is weakened beacuse of the damage to the lymphoctic cells.
<span>The nurse should tell the patient that eating a variety of healthy food is the best source of vitamins<span>. This is should be told by the nurse in a nice and emphatic manner, especially in this case wherein patients diagnosed with HIV are particularly emotionally sensitive. While this is true, the nurse should not advise the patient to stop taking his or her supplements; especially being diagnosed with HIV, his or her immune system is very frail and needs more than the usual nutrients compared to the normal population. </span></span>
