    Study Notes

    Signs and Characteristics of Hypoxia

    • Signs of hypoxia include cyanosis, which is a bluish discoloration of the skin due to inadequate oxygenation.
    • During breathing or cardiac emergencies, the heart rate typically increases in response to decreased oxygen levels.

    Breathing Rates and Oxygen Concentration

    • Normal adult breathing rate ranges from 12 to 20 breaths per minute.
    • Ambient air contains approximately 21% oxygen.
    • Rescue breaths deliver about 16% oxygen to the patient.

    Oxygen Delivery Systems

    • Variable-flow-rate oxygen systems allow for adjustments in flow rate based on patient needs.
    • Fixed-flow-rate oxygen systems provide a preset oxygen flow, typically benefiting consistent delivery.
    • Common features of fixed-flow-rate units include standardized flow settings and ease of use.

    Safety and Handling of Oxygen Cylinders

    • Oxygen containers must have a recognized organization's label, ensuring safety and compliance.
    • Before using an oxygen delivery device, ensure the oxygen flow is active and functioning properly.
    • Lubricating or cleaning regulators should never be done with petroleum-based products to avoid flammability risk.
    • When moving cylinders, do not roll or drag them to prevent damage.
    • Avoid attempting to alter or repair oxygen cylinders.

    Precautions in Emergency Situations

    • When using a defibrillator, be cautious of the presence of oxygen, as it can increase fire risk.
    • For patients already breathing, a nasal cannula should deliver oxygen at 1-6 LPM.
    • A nasal cannula can deliver approximately 22-44% oxygen at 6 LPM.
    • Nasal cannulas should be set to a fixed flow rate for consistent delivery.

    Resuscitation Masks and Oxygen Flow

    • Recommended flow rates for resuscitation masks range from 6 LPM to 15 LPM, providing up to 90% oxygen to non-breathing victims.
    • The main purpose of the oxygen inlet with resuscitation masks is to deliver high concentrations of oxygen during emergencies.
    • A non-rebreather mask should be used at a flow rate of 10-15 LPM, capable of delivering nearly 100% oxygen.
    • The one-way valve on a non-rebreather mask prevents exhaled air from re-entering the bag.

    Bag-Valve-Mask Resuscitators

    • Bag-Valve-Mask (BVM) devices should be used at a flow rate of 15 LPM, delivering a maximum of 100% oxygen.
    • BVMs allow for effective ventilation; their size helps create a seal around the patient's airway.

    Pulse Oximetry

    • Pulse oximetry sensors can be placed on fingers, earlobes, or foreheads to measure oxygen saturation.
    • The function of pulse oximetry is to monitor blood oxygen levels non-invasively.
    • There are two types of pulse oximetry: handheld and bedside units.
    • Pulse oximetry can misread oxygen saturation if carbon monoxide is present in the bloodstream.

    Oxygen Saturation Levels

    • Oxygen therapy is indicated for patients with saturation levels below 90%.
    • Normal oxygen saturation levels range from 95% to 100%.

    Airway Adjuncts and Suctioning

    • Common airway adjuncts facilitate maintaining patent airways, assisting in ventilation, and improving patient outcomes.
    • Patent airways are clear, unobstructed, and permit air passage.
    • Suctioning removes blood, fluids, and other material from the airway to assist breathing.
    • Two types of mechanical suction: electric and manual.
    • Hand-powered suction units are suitable for emergencies without electrical access.

    Suctioning Protocols

    • Indications for suctioning include visible obstructions or excessive secretions.
    • Contraindications for suctioning include severe facial trauma that could cause further injury.
    • Suction should not exceed 15 seconds for adults and 5 seconds for infants to minimize oxygen deprivation.
    • Position the patient on their side to allow for gravity to assist in draining fluids during suctioning.

    Safety Precautions

    • Turn the patient's head to the side during suctioning to prevent aspiration.
    • If oxygen saturation levels drop during suctioning, immediately pause and reassess the airway and suctioning technique.
    • There is a direct correlation between prolonged suction duration and the risk of oxygen deprivation, necessitating caution.
