Inhaled Medications01:23

Inhaled Medications

936
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen01:16

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

2.9K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

2.1K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

4.2K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

7.4K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Cardiopulmonary Resuscitation II: ACLS Airway Management01:22

Cardiopulmonary Resuscitation II: ACLS Airway Management

861
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Area of Science:

  • Pulmonary Medicine
  • Pharmacology
  • Medical Devices

Background:

  • Physicians often overlook inhaler device properties when prescribing inhaled corticosteroids (ICSs).
  • Little attention is paid to how different inhalers and formulations impact treatment efficacy and patient adherence.

Purpose of the Study:

  • To examine the influence of inhalation devices and user technique on asthma management outcomes.
  • To highlight the importance of device selection and proper technique for improving efficacy, safety, and adherence.

Main Methods:

  • Review of relevant publications to support the discussion on inhalation devices and techniques.
  • Analysis of factors influencing aerosol particle deposition and drug delivery.

Main Results:

  • Inhaler device choice impacts drug deposition, with optimal particle size ranging from 1 to 5 μm.
  • High rates of misuse exist for pressurized metered-dose inhalers and dry powder inhalers.
  • Patient education, technique correction, and device selection based on patient ability are vital for adherence.

Conclusions:

  • Inhaler device selection should prioritize cost-effectiveness, patient preference, and correct usage ability.
  • Regular checking and correction of patient inhaler technique are essential for optimizing asthma management.
