Heart rate (HR) is the number of times the heart beats in one minute; normal rates are 60 to 100 beats per minute. Stroke volume (SV) is the amount of blood that the heart pumps out with each beat; the normal amount is 60 to 100 milliliters per beat. A stethoscope is a device that amplifies sounds.hen measuring someone's apical pulse, make sure the patient is rested before trying to count the apical pulse rate. Have the patient lie down and find the apex of the heart. Ask the patient to breathe through his or her nose with normal breaths.
The basic ambient temperature rating point of most motors is 40Â°C. A motor rated for 40Â°C is suitable for installation where the normal surrounding air temperature does not exceed 40Â°C (104Â°F). This is the starting point.
MotorcraftÂ® ambient air temperature sensors are designed for durability and electrical performance. Highlights include: Threads and a seal on the sending unit are precisely matched to the vehicle application. A sensor within the unit features the proper output curve to work with the engine control computer to help prevent misreadings.
