Healthcare Provider CPR, AED, and First Aid

Why Healthcare Provider CPR Matters for Respiratory Therapists

Respiratory therapists (RTs) are among the first clinicians to respond when a patient stops breathing or loses a pulse. Because cardiac arrest can occur in any clinical setting—intensive care units, emergency departments, general wards, or during patient transport—every RT must maintain current Healthcare Provider–level CPR certification before entering clinical rotations. The American Heart Association (AHA) sets the evidence-based standards used in hospitals across the United States, and your program requires you to hold a valid AHA Healthcare Provider CPR card throughout your training.

High-Quality CPR: The Core Standard

High-quality CPR is defined by five measurable elements that the AHA emphasizes:

1. Compression rate: Push at a rate of 100–120 compressions per minute for victims of all ages.

2. Compression depth: At least 2 inches (5 cm) for adults; at least one-third of the chest depth for children and infants (approximately 2 inches for children; approximately 1.5 inches for infants).

3. Full chest recoil: Allow the chest to fully rise between compressions; do not lean on the chest. Incomplete recoil reduces blood flow back into the heart.

4. Minimize interruptions: Keep pauses in compressions as short as possible. CPR fraction (the proportion of time compressions are actually being delivered) should be as high as possible.

5. Avoid excessive ventilation: Deliver each breath over about one second, just enough to see the chest rise. Over-ventilation increases intrathoracic pressure and reduces cardiac output.

Compression-to-Ventilation Ratios

• Single rescuer, any age: 30 compressions : 2 breaths.
• Two rescuers, adult: 30 compressions : 2 breaths (switch compressor roles every two minutes to prevent fatigue-related depth loss).
• Two rescuers, child or infant: 15 compressions : 2 breaths.
• Advanced airway in place (e.g., endotracheal tube): Deliver continuous compressions at 100–120/min while the second rescuer gives one breath every 6 seconds; do not pause compressions for ventilation.

Infant and Child Differences

For infants, use two fingers on the center of the chest just below the nipple line (single rescuer) or the two-thumb–encircling hands technique (two rescuers) to achieve better depth and recoil. For children, use one or two hands depending on the child's size. Head-tilt–chin-lift opens the airway for children; for infants, maintain a neutral or slight sniff position to avoid kinking the airway.

AED Operation

Automated external defibrillators analyze heart rhythm and deliver a shock to correct ventricular fibrillation or pulseless ventricular tachycardia. The AHA sequence is:

1. Scene safety — confirm the environment is safe before approaching.

2. Power on — open the AED and turn it on; follow voice and visual prompts.

3. Pad placement — right pad below the right clavicle; left pad on the left side of the chest, below the armpit. For infants and small children, use pediatric pads or an attenuator if available; if not, place one pad on the front of the chest and one on the back.

4. Analyze — ensure no one is touching the patient; stand clear.

5. Shock — if advised, confirm everyone is clear and press the shock button immediately.

6. Resume CPR — start compressions within seconds of shock delivery; do not wait to recheck pulse.

Target: complete the full AED sequence in under two minutes from arriving at the patient's side.

First Aid: Airway Obstruction, Bleeding, and Respiratory Distress

Airway obstruction (choking):

• Conscious adult or child: deliver five back blows between the shoulder blades, then five abdominal thrusts (Heimlich maneuver). Alternate until the object is expelled or the victim becomes unconscious.
• Conscious infant: five back blows followed by five chest thrusts (not abdominal thrusts, which can injure infant organs). Never perform blind finger sweeps.
• Unconscious victim: begin CPR; each time you open the airway to ventilate, look for a visible object and remove it only if seen.

Severe bleeding control:

• Apply firm direct pressure with a gloved hand and a clean dressing.
• If bleeding is from an extremity and direct pressure fails, apply a tourniquet 2–3 inches above the wound; tighten until bleeding stops and note the time of application.
• Always wear gloves to protect yourself and the patient (standard precautions).

Recognition of respiratory distress:

Signs include increased work of breathing (use of accessory muscles, nasal flaring, retractions), abnormal respiratory rate, abnormal breath sounds, altered mental status, and abnormal skin color (pallor, cyanosis). As an RT, your clinical training will extend far beyond first aid recognition, but prompt identification and activation of emergency response are the immediate priorities.

Safety Reminders for the Lab

• Treat every simulation as a real scenario: practice proper body mechanics to avoid back injury during compressions.
• Clean manikin faces between users according to lab protocol to prevent cross-contamination.
• Use gloves during first-aid scenarios to build the habit of standard precautions.
• Never practice tourniquet application on a living person; use the training limb or manikin provided.
• Report any manikin or AED trainer equipment malfunction to the instructor immediately.

Certification and Clinical Placement

Passing both the AHA skills check (100% on all critical skills) and the written knowledge check (at least 84%) earns you your AHA Healthcare Provider CPR card. This card is a requirement for clinical placement and must remain current—typically renewed every two years. Losing certification mid-program means you cannot legally participate in direct patient care rotations, so renew early.
