Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure01:16

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure

Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue, improving...
Pneumonia V: Nursing management and Prevention01:30

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

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

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

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 III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

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...
Pneumothorax II: Pathophysiology01:08

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

    Summary

    High flow oxygen therapy effectively resolved pneumatosis coli symptoms and imaging findings in patients. However, colonic gas cysts recurred in some, indicating oxygen therapy does not eradicate anaerobic bacteria.

    Area of Science:

    • Gastroenterology
    • Pulmonology
    • Medical Therapeutics

    Background:

    • Pneumatosis coli, characterized by gas cysts in the colon wall, presents a diagnostic and therapeutic challenge.
    • Intermittent high flow oxygen therapy has emerged as a potential treatment modality for this condition.

    Purpose of the Study:

    • To evaluate the efficacy of intermittent high flow oxygen therapy in achieving symptomatic and radiological resolution of pneumatosis coli.
    • To assess the long-term outcomes and recurrence rates following oxygen therapy.
    • To investigate the impact of oxygen therapy on anaerobic bacterial colonization.

    Main Methods:

    • Five patients with pneumatosis coli underwent intermittent high flow oxygen therapy.
    • Disease extent was assessed using colonoscopy and contrast radiography before treatment.

    Published on: December 5, 2025

  • Bacteriological studies of stool and colonic mucosa were performed.

    • Main Results:

    • Symptomatic and radiological resolution of pneumatosis coli was observed in all five patients treated with oxygen therapy.
    • Recurrence of colonic gas cysts was noted in two patients at six months and one year post-treatment.
    • Oxygen therapy did not lead to the eradication of anaerobic bacteria from the stool and colonic mucosa.

    Conclusions:

    • Intermittent high flow oxygen therapy can effectively resolve pneumatosis coli, but recurrence is possible.
    • The treatment's mechanism may not involve complete eradication of underlying anaerobic bacteria.
    • Further research into long-term management and the role of bacterial flora is warranted.
