A condition affecting many people, characterized by difficulty breathing.

In most respiratory emergencies, reversible bronchial constriction is targeted for treatment.

Oxygen is a common medication in pre-hospital care, but its use in respiratory emergencies should be carefully monitored and individualized to each patient.

Medical substances that relax the bronchial muscles to improve breathing.

First-line medications for asthma treatment, used to relax airways during an asthma attack.

Oxygen is stored at high pressure (1800-2400 psi) in cylinders, then reduced to 60 psi for use.

The percentage of oxygen in the air a patient breathes in.

21% in normal room air.

A device that delivers low-flow oxygen through prongs in the nostrils.

1-6 L/min, delivers 24-44% oxygen.

Delivers high-flow oxygen (12-15 L/min) with a reservoir to prevent exhaled oxygen reentry.

Delivers specific oxygen concentrations (24%, 28%, 35%, or 40%) using adjustable inserts.

Uses oxygen or compressed air to convert liquid medicine into a mist for lung treatment.

A group of lung diseases that cause airflow obstruction and breathing difficulties.

A situation where someone's breathing is triggered by low oxygen levels in the blood, rather than increased carbon dioxide levels.

Because COPD patients rely on low oxygen levels to stimulate breathing. Too much oxygen can suppress this drive, leading to respiratory failure.

A common medication used to treat asthma and other respiratory conditions by relaxing the muscles in the airways, opening them up.

A bronchodilator medication used to relax the muscles in the airways, often used in combination with salbutamol to treat asthma and COPD.

When a Metered Dose Inhaler (MDI) is not available, hold it 2 inches away from the patient's mouth.

Asthma can be triggered by factors inside (intrinsic) or outside (extrinsic) the body.

Inhaled beta2 drugs are the first-line treatment for asthma.

Salbutamol (Albuterol) is a commonly used inhaled drug to treat reversible bronchospasm.

If asthma symptoms persist despite bronchodilators, corticosteroids may be considered in the prehospital setting.

PEFR measures the maximum speed of air exhaled, helping assess asthma severity and response to treatment.

In severe or life-threatening asthma, hydrocortisone and adrenaline are administered to suppress inflammation and relieve bronchospasm respectively.

Asthma is a chronic lung condition characterized by reversible airway obstruction due to inflammation and bronchospasm. This means the airways become narrower, making it difficult to breathe.

Bronchospasm is a rapid tightening of the muscles around the airways in the lungs, causing them to constrict and narrow. This can be triggered by allergens, irritants, exercise, or other factors.

Asthma involves three distinct phases: 1) Airway narrowing due to inflammation, 2) Bronchial spasm (muscle tightening), and 3) Increased mucus production. These combined make breathing difficult.

Edema in asthma refers to swelling of the lining of the airways. This swelling adds to the airway narrowing, further restricting airflow and making breathing difficult.

Nonselective bronchodilators act on multiple types of receptors in the body, including alpha, beta1, and beta2. They can cause side effects like increased heart rate and blood pressure.

Selective bronchodilators primarily target beta2 receptors in the lungs, causing relaxation of the airways and improving breathing. They produce fewer side effects.

Nebulization converts liquid medication into a fine mist that can be inhaled. It is a common method for delivering bronchodilators in respiratory emergencies.

A spacer device is used with a metered-dose inhaler (MDI) to slow down the delivery of medication, allowing it to reach deeper into the lungs more effectively.
