The Vital Role of Oxygen

Oxygen in the Environment

**Oxygen** is a crucial element for sustaining life. In the environment, approximately **21%** of the air consists of oxygen. When we inhale, we take in this 21%. However, when we exhale, our bodies use about **5%**, leaving approximately **16%** oxygen in the exhaled air.

Oxygen in CPR and Emergency Situations

When administering CPR to an animal, the air we blow out contains roughly **16% oxygen**, which is more than sufficient to support life. Supplementary oxygen can be provided in cases where an animal has been exposed to smoke, fire, or other illnesses.

Access to Oxygen

While not everyone may have access to oxygen, some do, which is why it's included in this course. Special considerations apply when handling oxygen, as it is a key component of the fire triangle and can combust. Oxygen may be available in certain workplaces, such as those with emergency oxygen kits or veterinary practices with on-site oxygen.

Types of Oxygen

Oxygen comes in different forms, including standard BOC cylinders and piped oxygen systems commonly found in veterinary practices and hospitals. Medical-grade oxygen, which is 100% pure, is used for medical purposes to ensure safety.

When to Use Oxygen

**Hypoxia**, a condition characterized by insufficient oxygen reaching the body's tissues, warrants the use of oxygen. In situations like car accidents or cases of smoke exposure, quickly administering oxygen can increase oxygen saturation in the body, promoting recovery. Oxygen is also valuable in first aid, particularly during CPR or when providing supplementary oxygen to animals in potentially hazardous situations, such as drownings.

Conclusion

**Oxygen** plays a vital role in animal care, aiding in the treatment of various conditions and emergencies. Its timely administration can significantly impact an animal's chances of recovery and well-being.
