Abstract:
Contact urticaria is a transient, wheal-and-flare response at the site of contact with a substance. We report a case of a military fighter pilot, with a background history of seborrheic dermatitis and steroid-induced facial skin atrophy, who subsequently developed contact urticaria from an oxygen facemask. Skin protection products such as barrier creams were used to try and minimize the provocation of contact urticaria from the oxygen mask whenever he flew, but without success. He was eventually permanently restricted from flying fighter aircraft.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Hyperpnea and Hyperventilation
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
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,...
