Breathing In (Inhalation)
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs).
Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin (HEE-muh-glow-bin) helps move oxygen from the air sacs to the blood.
At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery.
Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues.

Breathing Out (Exhalation)
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs.

Advise Mr. Walker to call 911 and be seen in the emergency room. SOA, pressure in the chest and sweating (diaphoresis) are i indicators of heart attack. I would suggest a low dose of baby aspirin too to thin the blood in the event it is a heart attack.
Answer:
3. "It is all right to use an electric razor for shaving only if I leave it plugged in for a short time."
Explanation:
Oxygen therapy refers to the administration of supplemental oxygen in order to increase or maintain oxygen saturation above 90%, thus correcting the damage caused by hypoxemia. This technique has as its main objective to increase the oxygen level that is exchanged between the blood and the tissues.
Home oxygen administration is a very important item to guide patients and families. This is because most of the time the use of oxygen is done through the use of torpedoes that will be inside the patient's home. Thus, all procedures related to the torpedo location in the patient's home, contact with heat, solutions and fire, in short, all the risks involved with home oxygen administration are fully demonstrated and directed to all those who remain in the patient's home. patient, including nursing.
Electronic braces used near the patient's face with oxygen therapy should also be avoided, as they can cause damage to the tube that is close to the patient's face, as their use causes them to become hotter and this is very dangerous for those who undergo treatment with oxygenation. For this reason, a patient who says "It is all right to use an electric razor for shaving only if I leave it plugged in for a short time" shows that he is not well informed about oxygen therapy and needs more information.
