Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
YES
Explanation:
When they first hit the ground, the impact makes them forget about the pain. Some people might not feel the pain due to them hitting their head at a certain spot which is dangerous. Breaking a bone is like cracking a part of your body, but instead of stopping the crack it continues till you feel a hard like object penetrating the inside of your skin.
Feedback loop
- feedback means telling whether it was good or bad or in this case, works or not.
Answer:
The asnwer is C) flush with water for 5 or more minutes.
Explanation:
When treating a patient with chemical burn in the eyes, the first thing to do is wash the eyes for 5 minutes or more. Once in the emergency department the patient must continue washing the eye and remove any chemical residue. It is coordinated with the application of natural tears and the obstruction of the affected eye. Be medicated analgesic, antibiotic, corticosteroid and cycloplegic drugs.
