When someone is dieing and can’t breathe
Hi!to control nose bleeding is to sit down and firmly pinch the soft part of your nose,just above the nose strils,for at lest 10-15 minutes if that doesn't work it is best ot get a doctor.
The P wave causes atrial contraction, QRS causes ventricular contraction, T wave is the ventricular refill period, and a period to prepare for another action potential via refilling electrolytes.
