Final answer:
d. Respiratory therapy. Techniques such as pursed-lip breathing and diaphragmatic breathing can increase efficiency in the lungs. Safety precautions when using oxygen equipment include proper ventilation, avoiding heat sources, and regular equipment checks.
Step-by-step explanation:
Efficiency in the lungs can be increased through techniques such as pursed-lip breathing. Pursed-lip breathing involves taking slow, deep breaths in through the nose and exhaling slowly through pursed lips. This technique helps to reduce the work of breathing and improve oxygen exchange in the lungs. Another technique to increase efficiency is diaphragmatic breathing, which involves breathing deeply into the diaphragm rather than shallow breathing into the chest. This technique helps to fully expand the lungs and increase lung capacity.
When using oxygen equipment in the home, it is important to follow safety precautions. Make sure the equipment is placed in a well-ventilated area to avoid the build-up of oxygen. Keep the equipment away from open flames, sparks, or sources of heat to prevent fire hazards. Regularly check the equipment for any signs of damage or malfunction. It is also important to follow the instructions provided by the healthcare provider or respiratory therapist regarding the use and maintenance of the equipment.
