L- decomposed by Light
O- vasOdilatOr, brOnchOdilatOr, uterine relaxtant
TH- Thymol as preservtive

Mnemonic for causes of failed intubation is : INTUBATION

Infections of larynx
Neck mobility abnormalites
Teeth abnormalties(loose tooth,protuberant tooth)
Upper airway abnormalties (strictures or swellings)
Bull neck deformities
Ankylosing spondylitis
Trauma/tumour
Inexperience
Oedema of upper airway
Narrowing of lower airway

Mnemonic for differential diagnosis of poor breath sounds after intubation is: DOPE
DOPE stands for:

Displaced tube
Obstruction
Pneumothorax
Esophageal intubation

BURP stands for: Backwards, Upwards, Rightward Pressure
If during intubation, the glottis is not visible readily, the assistant can catch hold of the thyroid cartilage and push it backwards, upwards and towards the right
It greatly improves the view of the glottis and helps intubation

Ketamine causes stimulation of the cardiovascular system
It increases myocardial oxygen demand
The hemodynamic changes include increase in

Heart rate
Cardiac Index
Systemic Vascular Resistance
Systemic and pulmonary artery pressure

Since ketamine produces hypertension, it is rarely used in hypertensive patients

IPPV is invasive and non-physiological, and hence reserved for cases where non-invasive ventilation is not suitable.

Terminology

PEEP: positive end expiratory pressure
Cycling: change from inspiration to expiration or the reverse. It can be volume cycled, pessure cycled, time cycled or flow cycled.
Modes of ventilation: controlled mode, assist controlled mode, assist mode
Controlled mode – every breath by the ventilator; even if the subject wants breath spontaneously, it is not permitted. Volume and pressure controlled modes are available.
Assist control mode – IMV and SIMV (synchronized intermittent mandatory ventilation). SIMV removes the chance of fighting …

Checking for airway patency may be life saving in certain situations which may be mistaken for other conditions like an acute coronary syndrome. Usual cause of airway obstruction in an uncoscious patient is falling back of the tongue. Head tilt and chin lift / jaw thrus will help in this situation. But head tilt should not be used in trauma.
If the oropharyngeal reflexes are not adequate, an oropharyngeal airway is useful. If oropharyngeal airway is not suitable, a nasopharyngeal airway can be used. Advanced airways are considered if even this …
