1. Factors Affecting Pulse Rate

Pulse rate can vary due to several factors. Physical activity increases heart rate to meet oxygen demands. Emotional stress for example anxiety stimulates the sympathetic nervous system, raising pulse. Fever can elevate pulse, while cold lowers it. Medications like stimulants increase it, while beta-blockers reduce it. Heart conditions may also affect pulse rate

2. COPD Explanation and Blood Pressure Impact

COPD is a chronic lung disease that blocks airflow and makes breathing difficult. It's often caused by long-term smoking, as in David's case. Symptoms include chronic cough, wheezing, and breathlessness. Treatment involves quitting smoking, using inhalers, pulmonary rehab, and possibly oxygen therapy. COPD can increase pulmonary artery pressure, potentially leading to high blood pressure in the lungs and right-sided heart strain.
