What is the value of monitoring pulmonary artery pressure in the ventilated patient? What factors would create unreliable results?

Expert Solution

Pulmonary blood pressure reflects the pressure the heart exerts to pump blood from the heart through the arteries of the lungs.

Normal pulmonary artery pressure is 8-20 mm Hg at rest. If the pressure in the pulmonary artery is greater than 25 mm Hg at rest or 30 mmHg during physical activity, it is abnormally high and is called pulmonary hypertension.

Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure (P̄pa) ≥25 mmHg at rest on right heart catheterisation (RHC).

Factors that create unreliable results-

While pulmonary hypertension has no cure, you can live an active, fulfilling life by working with your doctor to manage your symptoms. Talk to your doctor before taking over-the-counter medicine, as some can worsen symptoms of pulmonary hypertension or interfere with prescriptions and keep a list of medicines with you. Ask whether you should get a pneumonia vaccination or flu shot. Additionally, pregnancy can pose serious risks for women with pulmonary hypertension, so be sure to discuss birth control options with your physician.

Create a matrix of hemodynamic values including systemic blood pressure, central venous pressure, pulmonary artery pressure, pulmonary wedge pressure, mean arterial pressure, right atrial pressure, right ventricular pressure, left atrial pressure, stroke volume, cardiac output, systemic vascular resistance, and pulmonary vascular resistance, indicating for each the following data: normal values, causes of increased values, and causes of decreased values.

What are factors that affect pulmonary ventilation

What are factors that affect pulmonary ventilation Direction of diffusion of gasses Pulmonary volumes and capacities Methods of gas transport O2-Hemoglobin saturation curves - what determines O2 saturation; what affects O2 satura What is Infant Respiratory Distress Syndrome? How are the chest wall and lung coupled during ventilation What is respiratory acidosis? Alkalosis? What is the strongest signal stimulating respiration? How does the body compensate for a ventilation-perfusion mismatch?

Imagine a pulmonary embolus breaking up and entering the pulmonary artery supplying blood to an entire lobe of the left lung, blocking 75% of the pulmonary arterioles in that lobe. Describe the effects on the arterioles and bronchioles in this lobe in response to this event.

12) Imagine a pulmonary embolus breaking up and entering the pulmonary artery supplying blood to an entire lobe of the left lung, blocking 75% of the pulmonary arterioles in that lobe. Describe the effects on the arterioles and bronchioles in this lobe in response to this event. 13) Elevated potassium levels in the body (hyperkalemia) is a serious condition, resulting in a severely decreased ability for muscle fibers and neurons to reploarize. The adrenal cortex can respond to this. However,...

3. A blood pressure monitoring device records patient blood pressure (in mmHg) twice per minute. It is set to alert the doctor whenever the patient's systolic blood pressure falls below 75 mmHg. The measured signal includes some Gaussian noise: that is, at each measurement, the measured blood pressure PM equals the true blood pressure P, plus some noise. This noise has a Gaussian distribution about zero with a standard deviation equivalent to 2.8 mmHg. a. What is the probability that...

If a patient has renal artery stenosis (narrowing of the renal artery) due to atherosclerosis, what is the impact of this on GFR? Specifically, be sure to discuss the impact on the afferent and/or efferent arterioles as well as effects on hydrostatic and/or oncotic pressure.

A common heart defect is the “d-Transposition of the Great Arteries” in which the pulmonary artery and the aorta are attached to the opposite ventricles. Veins attach correctly, only arteries are switched. Given what you know about how blood circulates, indicate specifically how blood flow would be different (trace a path of blood flow) and what specific types of health problems it would each cause for an individual with that defect.
