Malignant hypertension is a medical emergency which is characterised by a severe rise in the blood pressure which cannot then be lowered. It is diagnosed by the presence of advanced retinopathy in the presence of a diastolic blood pressure of over 120 mm Hg. Malignant hypertension is more prevalent in African type people and also more common in smokers. It affects about 1% of those people already suffering with high blood pressure.
Most lung cancer starts in the cells lining the main air passages, or bronchi. In their cancerous state, these cells lack cilia which are tiny hair like substances which normally catch and remove foreign particles inhaled into the lungs. Mucous in the lungs which is usually cleared by bronchial cilia then becomes trapped, blocking air passages and causing respiratory problems. There are several different types of cancer affecting the lungs; the principal cancers are described below.
There are many variables to consider when assessing blood pressure in people from moment to moment and these can include Emotion Exercise Respiration Heavy meal Smoking Alcohol intake Temperature Pain Bladder problems Link Text Age Gender Race When having their blood pressure taken, the person should be relaxed and if possible sat in a quiet room with the temperature set at a comfortable degree. If possible the person should have had a period of relaxation before their blood pressure is taken.
There are currently many options in orthopedic (bone) surgery for people with arthritis. Joint replacement is the most common option. According to the National Joint Replacement Foundation, (NJRF) over 435,000 Americans underwent this procedure last year. These numbers have boosted joint replacement to one of the most successful medical discoveries and the absolute most significant surgery in the field of arthritis treatment. Joint replacement is the process of removing ones entire joint as well as any damaged tissue and replacing it with a metal prosthesis.
Joints can handle heavy pressure. For example, knees handle a force of three to four times a persons total body weight on average just talking a walk. The force of a deep knee bend during a squat can increase to nine times the body weight. So just imagine multiplying weight of more than 150 pounds times a minimum of three or four, and then even more. That can sure add up to a lot of heavy work on knee joints over time.
To check if a person has a sleeping disorder, a diagnosis is made by a physician specially trained in sleep medicine. After a physical examination of the upper airway and an interview with lots of questions, if it the tests have determined that the patient has a sleeping disorder, one will have to undergo a polysomnogram (sleep test). Most sleep centers and labs monitor 16 different sleep parameters including EEG, EKG, eye movement, chin movement, air flow, chest effort, abdomen effort, SaO2, snoring and leg movement.
The amount of sleep a person needs actually depends on the age and amount of physical and mental activity a person engages to. For example, an infant who does not perform any strenuous task and undergoing a period of rapid growth needs 16 to 18 hours of sleep. The same thing applies to teenagers who are experiencing the biological challenges of puberty. More often than not they require at least 9 hours of sleep every night for that matter.
Sleep apnea is a health condition far more serious than what most would think of. Sleep apnea is a health condition that happens when one’s breathing during sleep stop for a while, usually 10 seconds or even longer. Sleep apnea could happen 5 to 45 times per hour. Sleep apnea is usually associated with choking sensations and often leads to headaches and sleepiness during the day. Its moderateness or severity is measured with respect to the frequency of episodes per hour, whether you have no breathing (apnea) or slower breathing (hyponea).
