Respiratory masks are divided into nasal masks, oral and nasal masks, nasal masks (nasal pillow masks), oral masks, full-face masks and helmet masks.
(1) The nasal mask covers the nose and breathes through the nose. It can be used by general patients, but it is not suitable for severe patients or patients who need to breathe through the mouth. Nasal masks should be preferred for patients on a ventilator for the first pressure titration test or with mild respiratory failure.
(2) The mouth and nose mask covers the mouth and nose, and the patient can breathe through the mouth or nose, which is beneficial for patients who are used to breathing through the mouth during sleep. Oral and nasal masks are suitable for patients with nasal congestion, dry mouth and nose, and air leakage from the mouth, and are also the first choice for patients with severe respiratory failure.
(3) Nasal congestion mask only needs to insert the nose pads into the nostrils, which has the least contact with the facial skin. It is light and comfortable, breathes through the nose, and has a wide field of vision. It is suitable for patients with special facial support structures and claustrophobia. Patients with mild snoring are also suitable. Can be used; however, it is not suitable for patients with nasal diseases and those who treat high pressure.
