Close the patient's nostrils with a pinch to help create an airtight seal. Completely cover the patient's mouth with your own. Give two breaths after 30 chest compressions.
Close the patient's nostrils with a pinch to help create an airtight seal. Completely cover the patient's mouth with your own. Give two breaths after 30 chest compressions (the 30:2 cycle of CPR) Each breath should last for about a second and be strong enough to cause the patient's chest to rise.
Chest compressions and artificial ventilation are used in cardiopulmonary resuscitation (CPR) to sustain blood flow and oxygenation after cardiac arrest (see the images below). Although patients with cardiac arrest have low survival rates and poor neurologic outcomes, prompt, proper resuscitation—including prompt defibrillation when necessary—and timely post-cardiac arrest care are associated with improved survival and neurologic outcomes.

Answer:
1. Modified formulae for calculating tree height.
.
2. C++ program to calculate tree height.
#include<iostream>
#include<math.h>
using namespace std;
int
main ()
{
double treeHeight, shadowLenghth, angleElevation;
cout << "Please enter angle of elevation and shadow length" << endl;
cin >> angleElevation;
cin >> shadowLenghth;
//Modified formulae to calculate tree height.
treeHeight = tan (angleElevation) * shadowLenghth;
cout << "Height of tree is:" << treeHeight;
}
Output:
Please enter angle of elevation and shadow length
45
12
Height of tree is:19.4373
Explanation:
Since no programming language is mentioned, so solution is provided using C++.
In the above C++ program, first angle of elevation and length of shadow provided by user will be stored in variables angleElevation and shadowLength.
Then using the modified formalue height of tree will be calculated and stored in variable treeHeight. Final result is displayed to user.
The fix to the problem in the code is as follows:
def sum(a, b):
total = a + b
print(total)
sum(1, 0)
<h3>How to determine the problem and the fix to the problem?</h3>
The code is given as:
def sum(a, b):
total = a + b
print(total)
sum(total, a)
sum(1, 0)
When the above code is run, one or both of the following would occur
- An infinite loop because the program cannot end the recursion
- An error when the maximum memory is used
The problem in the code is that, the recursive function do not have a condition to end itself.
The fix to the problem is to remove the recursive definition.
So, we have the fixed code to be
def sum(a, b):
total = a + b
print(total)
sum(1, 0)
