Techniques for Artificial Breathing and Resuscitation

Artificial respiration techniques are critical in situations where natural breathing has ceased or is inadequate. These methods can be lifesaving during emergencies such as drownings, choking incidents, strangulations, suffocations, carbon monoxide poisoning, and electric shocks. Effective artificial respiration not only helps to maintain an open airway but also facilitates the exchange of oxygen and carbon dioxide in the lungs until spontaneous breathing resumes.

Methods of Performing Artificial Respiration

Several techniques have been developed to artificially inflate the lungs, primarily focusing on the mechanics of breathing. Two notable methods are often employed: one developed by Schaffer and another by Sylvester.

Schaffer’s Technique

This approach requires the patient to lie face down with one arm extended overhead and the other bent at the elbow. The patient's face rests on the forearm, allowing for potential airflow through both the mouth and nose. The rescuer positions themselves on the patient's waist, applying pressure to the abdomen to facilitate expiration. This is followed by a backward tilt to encourage inhalation. Each cycle typically consists of about three seconds for exhalation and two seconds for inhalation. This method has the advantage of being performed in a prone position, allowing for effective drainage of fluids from the abdomen and lungs. It is straightforward and can be sustained over time. However, it has notable limitations, such as the necessity for passive inhalation and active exhalation, which can be counterproductive physiologically. Additionally, it may be ineffective for abdominal injuries.

Sylvester's Technique

In this technique, the patient is positioned face down with their head fully extended and a pillow placed beneath their shoulders. The rescuer kneels at the patient's head and pulls the patient's arms upward to induce inhalation. By placing a hand on the patient’s chest and pivoting forward, the rescuer encourages exhalation. Each inhalation lasts for three seconds, followed by a two-second exhalation. This method allows for good ventilation, provided that both phases are actively managed. However, it is not suitable for patients who have inhaled water, and it may be exhausting for the rescuer, necessitating assistance. It is also contraindicated in cases of fractured ribs or chest injuries.

Mouth-to-Mouth Resuscitation

This technique is among the most effective for artificial breathing. The rescuer kneels beside the patient’s neck, ensuring a straightened airway by placing a pillow under the patient’s shoulders. The rescuer then covers the patient’s mouth with a handkerchief and closes the nostrils with one hand before delivering expired air into the patient’s mouth. This method prompts passive expiration upon removal of the rescuer's mouth, effectively stimulating the patient’s respiratory system with carbon dioxide-rich air, improving oxygenation.

Mechanical Ventilation Devices

Artificial ventilators, or breathing machines, are essential for patients requiring respiratory support. These devices deliver air directly into the lungs, ensuring an adequate supply of oxygen to the bloodstream. Medical personnel typically operate these machines, often requiring intubation—where a tube is inserted through the mouth or nose into the trachea. A tracheostomy may also be performed, allowing direct access to the trachea.

Types of Artificial Breathing Equipment

Various devices are employed depending on the patient’s condition and symptoms. Common artificial breathing apparatus includes:

• CPAP (Continuous Positive Airway Pressure)
• Humidifiers
• Chest Compression Systems
• Oxygen Delivery Devices
• Nebulizers
• Oxygen Regulators
• CPR Pocket Masks
• CPR Devices
• Oxygen Flowmeters and Selector Valves
• Oxygen Fittings

Each device serves a specific purpose in managing respiratory conditions, tailored to the needs of individual patients.
