Intracranial pressure

Imagine you’re out to lunch with a couple of friends from work when your stomach starts to cramp. Oh no, not now, you start to think. You start looking around the room looking for the closest bathroom. You politely excuse yourself from the table and sprint to the bathroom only to find a line. You’re sweating because of the pain, nauseous, and anxious you’re going to have an accident right here in front of everyone. This is how it can feel for someone suffering from irritable bowel syndrome. The…

angina (Darovic, 2002). The IABP will reduce the resistance to the left ventricular ejection and improve coronary perfusion as well as systemic blood flow (Darovic, 2002). During diastole, the balloon inflates to increase diastolic pressure higher than systole pressure while displacing blood volume equivalent to its inflation volume (Darovic, 2002). IABP will enhance…

system eliminates or keeps the excess or shortage solutes or water. When water intake is not enough, blood volume decreases, blood pressure goes down, and this leads the renin secretion which promotes releasing of angiotensin II for increasing osmotic pressure to stimulate hypothalamus. Also water loss is regulated by ADH with water reabsorption mechanism. When osmotic pressure increased ADH also secreted to promotes absorbing water from the collecting ducts causing the produce of concentrated…

Angiotensin Converting Enzyme (ACE) inhibitors lower blood pressure and produce vasodilation by inhibiting ACE – blocking the conversion of angiotensin I to angiotensin II, key mediators of the Renin-Angiotensin-Aldosterone System (RAAS). RAAS is the main mechanism for controlling BP. Angiotensin II is a vasoconstrictor and works by binding to angiotensin I receptors on smooth muscle – these are joined to a Gq protein and the IP3 signal transduction pathway. ACE usually breaks down bradykinin.…

experience a spike in their heart rate and blood pressure. In a recent study on the effects of epinephrine on the heart (Fuenmayor and Gomez 2016) the results showed that when the hormone epinephrine was directly injected into the system there were no harmful effects, however the systolic blood pressure and heart rate of the patient increased to up to 10% higher than the basal reading. This study would…

Clinical signs are caused by damage to the grey matter and white matter of the spinal cord. Pain, temperature, vibration, proprioception and dermatomal sensations all may be diminished, which will depend on the exact area of the cord or nerve-root which is compromised. Patients may also complain urinary urgency, hesitation and frequency but infrequnetly of urinary incontinence and retention. Fecal incontinence is very rearly present. Decreased tendon reflexes (hyporeflexia), muscle weakness and…

Tiffany, I really enjoyed reading your discussion post. I especially liked the way that you incorporated the topic and influence of heredity on an invidual's attitudes and beliefs. One of the major arguments and/or debates within the psychological community is whether individuals are mostly influenced by nature or nurture. I happen to believe that there is a symbiotic relationship between the two influences; whereas the environment can either foster or suffocate those actions, behaviors, and…

To diagnosis AS a transthoracic echocardiogram (TTE) is completed, with two dimensional doppler (2D). An Echocardiogram is a diagnostic study that uses ultrasound waves transmitted through a transducer using a conducting gel to create an image of the heart. Ultrasound waves are cyclic in nature and at a frequency that are not audible within the parameter of human hearing (Fridman, V., 2013). The transthoracic approach provides visualization of the heart and its structures. Throughout TTE the…

Evelina Hospital I was able to witness a lot of these and see how the work. The stress tests work by monitoring your heart whilst you preform various exercises, this can include running on a treadmill or going on an exercise bike while your blood pressure is taken as well as an electrocardiogram to measure your heart…

are objective measures of physiological function that are used to monitor acute and chronic disease and thus serve as a basic communication tool about patient status.1 Vital signs consist of the measurements of heart rate, respiratory rate, blood pressure, and body temperature. Vital signs are used to monitor patient’s health status and also to monitor their recovery from certain diseases. Numerous physiological and pathological changes may occur with age and alter vital signs.1 Respiratory…
