ABSTRACT
The cardiopulmonary system, also known as the cardiovascular-respiratory system, this system involves the heart, blood vessels, and lungs working together to ensure the body's cells receive oxygen and nutrients while eliminating metabolic waste products. as well as the exchange of gases (oxygen and carbon dioxide) between the blood and the external environment through respiration. Body mass index or BMI is a statistical index using a person's weight and height to provide an estimate of body fat in males and females of any age. For a normal weight the BMI is greater than or equal to 18.5 to 24.9 kg/m2 , an underweight BMI is under 18.5 kg/m2 , an overweight BMI is greater than or equal to 25 to 29.9 kg/m2 , for obesity the BMI is greater than or equal to 30 kg/m2 . This study is aimed is to investigate the correlation between body mass index and some cardiopulmonary function indices in healthy male adults. A total of 15 apparently healthy adult male subjects was used to carry out this study with 5 subjects per age range. The age ranges was between ages 18 – 25, between ages 25 – 35 and between ages 35 – 50. To measure the weight the subjects were meant to remove shoes, bulky clothing and ornaments that could possibly interfere with the measurement and stand with both feet in the center of the weighing scale. To measure the height the subjects were meant to remove shoes, hat and bulky clothing and that could possibly interfere with the measurement and stand against the stadiometer with heels together, leg straight, arms at side and shoulder relaxed. The readings where recorded and the BMI calculated. To measure FVC, PEFR, FEV1, the subjects sat upright and relaxed, wore nose clips to prevent air from escaping through the nose then placed the mouthpiece of the digital spirometer between their lips and sealed tightly, the subjects took deep breaths and exhaled as forcefully as possible for at least 6 seconds. Lastly subjects pulse and arterial pressure were taken, subjects were made to rest in a chair next to a tale for 5 to 10 minutes. Their arm was at rest comfortably at heart level. Afterwards the cuff was placed around the arm. The fabric fastener was used to make the cuff tight. The digital blood pressure monitor was turned on. Participant was made to sit quietly and watched them monitor. Pressure readings were displayed on the screen after this, the cuff was deflated and the record of the date, time, systolic and diastolic pressure was taken. Results obtained from the study showed that at ages 18-25 and 26-35, pulse and systolic blood pressure are correlate negatively relative to BMI though not with a significance (p > 0.05). However, the diastolic pressure was positively correlated relative to BMI though without a significance (p > 0.05). Furthermore, the age group of 36-50 the pulse and systolic blood pressure a showed positive correlation relative to BMI while the diastolic blood pressure showed a negative correlation relative to BMI though not with a significance (p > 0.05). It was observed that as the age group increased, pulse and systolic pressure tends towards a positive correlation while the diastolic blood pressure tend toward negative correlation relative to the BMI. Investigation of the pulmonary function of the lungs relative to the body mass indices showed a positive correlation for PEF, FVC, and FEV1 for the age group of 18-25 though with a significance (p > 0.05). However, as the age increased, the PEF showed a negative correlation while FVC showed a very weak correlation to BMI though without a significance (p > 0.05).
